Why Use Genuine Spares in an Air Compressor

by vemcoblogs -
ELGi Air Compressor Dealers in Mumbai

The market is flooded with unbranded air compressor spare parts. If you’re an air compressor owner, you could be tempted to procure these inexpensive but substandard spares for it. While this may save you some quick bucks and get your air compressor up and running, it could prove to be rather expensive in the long run. VEMC is one of the leading ELGi Air Compressor Dealers in Mumbai, and in this blog, we tell you why you must only stick to genuine spare parts for your air compressor. 

Genuine spares mean optimal performance

Genuine spare parts are specifically designed for a certain make or model of air compressors and are therefore perfectly compatible with it. This reduces wear and tear, and risks of malfunction, while improving its efficiency. Genuine spares thus ensure that your air compressor performs at its optimum best with a minimum incidence of breakdown.

Quality and reliability

Genuine spares are made from high-quality durable material and are put through stringent quality assurance tests. The Original Equipment Manufacturer (OEM) of air compressor parts often sets high standards of quality for their parts. This means the compressor can offer greatest possible resistance to various environmental pressures and ensure utmost reliability.

Reduced safety risks

Since air compressors often operate at high temperatures and pressures, safety is always a concern for owners and operators alike. Installing non-genuine spares can put the safety of operators at serious risk due to failures and accidents. The best defence against such incidents is using genuine spare parts only. These are made by keeping in mind the highest safety standards and regulations.

Compressor warranty

Many air compressor manufacturers will void your warranty on finding out that you have used non-genuine spare parts. This is because non-genuine spares offer lower levels of compatibility and rather than improving performance can cause damage to other parts. Besides, non-genuine parts may not comply with the regulatory standards set by the OEM. On the other hand, they offer full warranty coverage for a specified period for genuine spare parts. 

Efficiency and energy savings

Air compressors have critical parameters like flow rate, pressure and consumption. Only genuine spare parts are constructed to ensure the perfect fit and maintain these parameters at optimum levels. This enables you to operate your air compressor at the highest possible levels of efficiency, thus accruing plenty of savings on your energy bills. This also means your air compressor has a lower lifespan costs and a lesser impact on the environment.
Quite clearly, if you are an air compressor user, there are multiple reasons why you must only trust a genuine spare parts manufacturer for replacement.

5 key benefits of installing a screw air compressor over a reciprocating air compressor

by vemcoblogs -
Screw Compressor

If you’re planning to buy a new air compressor, you must wonder which one suits your requirements better. Air compressors are after all a hefty investment in your operations and the decision must be made after careful planning. While both screw and reciprocating air compressors find utility across industries, the former has some well-established benefits over the latter. VEMC is the leading ELGi Screw Compressor dealer based in Mumbai, and in this blog, we take you through 5 key benefits of installing a screw air compressor over a reciprocating air compressor.

Working principle of screw air compressor vs reciprocating air compressor

First, let us look at how a screw compressor is different from a reciprocating air compressor. 

Rotary screw compressors simply work by compressing air using helical screws known as rotors. This forces the air through the chambers and compresses it into a smaller space. With this mechanism, as the rotors turn, the air gets continuously compressed. Reciprocating compressors on the other hand work by using pistons which move back and forth. This reduces the air mechanically, leading to an increase in pressure. 

Benefits of screw air compressors over reciprocating air compressors

  1. Consistent output and high volume: Screw compressors operate continuously unlike reciprocating compressors. This gives a smooth output that can be crucial in tasks that need consistent air pressure. For tasks which require higher volumes of compressed air, screw air compressors are better suited than reciprocating air compressors.
  1. Efficient, compact and silent: When it comes to energy consumption, screw compressors are more efficient than reciprocating air compressors. This helps reduce operation costs over time. Screw compressors are also more compact which makes them adaptable to various environments. They’re usually noiseless and are thus better suited for residential areas and other noise-sensitive settings.
  2. Lower maintenance needs and longer lifespan: Screw air compressors do not have pistons, valves or any other moving parts. This reduces the levels of friction, wear and tear, maintenance needs, and downtime. Due to this, screw air compressors tend to have a longer working life than reciprocating air compressors. Their downtime is also lesser and lifespan costs are under control.
  3. Higher quality of air: Since screw air compressors operate with sealed chambers and have better filtration systems, they tend to offer a higher quality of air as compared to reciprocating compressors.
  4. Adaptable: Using Variable Speed Drives (VSDs), screw air compressors can easily adapt the supply of compressed air to the fluctuating demand. This saves energy and ensures efficient operations.

Due to the above-mentioned benefits, screw air compressors are used in a diverse range of industries and applications. These are usually preferred in industries like manufacturing, construction, oil and gas, food and beverage, pharmaceuticals, power generation, mining, chemicals and petrochemicals.

5 reasons to choose LD series direct drive reciprocating air compressor

by vemcoblogs -

While most people are aware of rotary screw compressors and piston air compressors, there is another classification on the basis of how these are driven: Belt-driven and Direct Drive air compressors. The former has a V-shaped belt to drive the compressor through a pulley system while the latter are pulled directly by a crankshaft connected to the motor. VEMC is a leading air compressor dealers in Mumbai, and in this blog we talk about the 5 top reasons to choose the LD series Direct Drive reciprocating air compressor. 

  1. Direct drive compressors are better any day

For starters, direct drive air compressors have fewer component parts as compared to the belt-driven compressors. This means lesser wear and tear, lower costs of maintenance and a longer lifespan. These can also handle a much wider range of temperature as compared to belt-driven air compressors.

  1. ELGi LD series offers longer lifespan

The ELGi LD series is known for its long lifespan, thanks to its robust construction. It has a unique integrated drive with compact top block design and is built with cast iron and forged steel components. The optimised design of piston and wings offers a longer life. Its stainless steel valve plates are maintenance-free and ensure the pump is highly reliable.

  1.  Energy savings 

The pump has a common cooling fan which improves the efficiency and saves energy significantly. With the provision of running the top block independently, the pump is able to provide compressed air based on demand. The low operational speed produced using the highly efficient IE2 6-pole motor also contributes significantly to energy savings.

  1. Better safety and heat management

ELGi LD series compressors ensure safety by using the ASME designed receiver tank. It is also equipped with a starter and pressure switch with proven reliability. The larger aluminium inter and after coolers offer 44% more heat transfer and thus better cooling of the air compressor.

  1. Sustainable and environment-friendly

ELGi LD series compressors are in tune with the spirit of sustainability in a number of ways. Longer lifespan, energy efficiency and lower service costs are some prime features which substantiate its sustainable claims. However, the compressors also produce low noise levels which makes these a favourite, whether on the factory floor or in residential areas.

ELGi’s LD series compressors are clearly a pathbreaking innovation in the evolution of air management. These are highly suited for applications in rubber, metal, garage, plastics and woodworking industries, which typically required high-performing piston compressors to meet fluctuating air needs.

Difference between oil lubricated and oil-free piston and screw compressor

by vemcoblogs -

If you wish to purchase an air compressor, you could be faced with choosing between and oil-lubricated and oil-free compressor. Both have their pros, cons and suitabilities for different types of tasks and industries. VEMC is the leading ELGi screw compressor dealer in Mumbai, and in this blog, we tell you about the major differences between these two types of air compressors.

Piston vs screw air compressors

Before we go to the oil-lubricated and oil-free compressors, lets first talk about the difference between piston and screw compressors. The main difference lies in the way these compress the air. While a piston compressor use a piston driven by a crankshaft, a screw compressor uses two meshing helical screws. 

Role of oil in air compressors

Primarily, oil in air compressors acts as a coolant to dissipate the heat generated in the process of compression. It also acts as a lubricant as an air compressor has lots of moving parts which constantly rub against each other, causing friction and wear and tear. Thirdly, air compressor oil seals the compression chamber, thus also acting as a sealant. 

Pros and cons

Now that we know the role oil plays in an air compressor, lets jump to the pros and cons that oil-lubricated and oil-free compressors bring to the table.

Oil-lubricated compressors

ProsCons
1. These require very little maintenance and resolving technical issues is usually quite simple.1. These leave traces of oil which can cause problems in certain sensitive operations.
2. These tend to have a longer lifespan.2. These are often bulky, take up a lot of space, and are difficult to move around.
3. They produce very little heat or noise.
4. These are capable of performing heavy duty work and can be used in extreme conditions.

Oil-free compressors

ProsCons
1. They’re usually smaller in size and thus quite easy to move around.1. These generate more heat and noise.
2. They can deliver clean compressed air without any traces of oil.2. These compressors have more maintenance requirements.
3. These compressors require zero manual lubrication.3. They have a short lifespan as compared to oil-lubricated compressors. 
4. They are less costly than oil-lubricated air compressors.4. Unlike oil-lubricated compressors, these are not suited for heavy duty operations.

Which type of air compressor is best suited for your industry?

In operations and industries where slightest contamination can be problematic, oil-free compressors are the best choice. These include industries like:

  1. Paper
  2. Food and beverage
  3. Pharmaceuticals
  4. Electricals

However, in case there is no contamination risk as such, oil-lubricated compressors are any day a great choice, as these have low maintenance, longer lifespan, and produce less noise and heat.

Still not sure which compressor is the right choice for your business? Free free to get in touch with VEMC by calling us on 022 43436655 or emailing us at marketing@vemc.co.in. We are the leading ELGi screw compressor dealer based in Mumbai.

Selecting the Right Air Compressor for Tire Inflation: Balancing Power and Portability

Selecting the Right Air Compressor for Tire Inflation: Balancing Power and Portability

Air compressors are multi-purpose equipment and are put to a wide range of uses at home, businesses and factories. For instance, given the power they generate, they can be used for inflating your car tires to maintain an optimum air pressure. However, it is important to know which air compressor is right for which type of tire. VEMC is the top compressor dealer in Mumbai, and in this blog, we tell you how to select the right air compressor for inflating your car tires.

Factors to consider when choosing a tire inflator

  1. Flow rate: This refers to the volume of air that will be compressed and pushed into a tire during a certain span of time. If your vehicle has large tires, it is advisable to use an air compressor with a higher flow rate. Pick-up trucks and SUVs typically require inflators with higher flow rates.
  2. Maximum pressure: Bigger tires can take too long to inflate if your air compressor isn’t generating enough air pressure. Look for a compressor that can offer a pressure of 100-150 PSI to fill your tires fast. This is especially helpful if you’re running a car workshop or a tire factory. 
  3. Portability: Air compressors that operate wirelessly are more handy and portable as compared to the wired ones. These run on rechargeable batteries and do not require any external power supply. These are the best choice and provide a lot of freedom to users if they need to move around too much to inflate a number of vehicles.
  4. Power source: Inflators can either be electric or battery-operated. The latter are more flexible to use as they can be moved around without hassles. However, for longer operations at one location, some users may prefer an electric tire inflator.

Selecting the right balance between power and portability

When it comes to selecting the right air compressor, power and portability appear to be the most visible trade-off. For instance, what typically determines the output of an air compressor is its tank. Bigger the tank, more air it can store and greater will be its productivity. However, it will lower the portability of the air compressor as it may make it bigger and heavier. 

In case you wish to move or travel around with your air compressor, portability becomes an important feature to consider. However, if most of your operations are stationary, it would be much better to look for higher capacity and power.

Safety precautions for tire inflation

Tire inflation can be a slightly dicey task if the right precautions aren’t taken:

  1. It must only be performed by trained personnel.
  2. Read and follow all the product warnings and procedures on your inflator.
  3. Always use inflation cages/restraining devices.
  4. Always center the wheel in an upright position inside an inflation cage.
  5. Wear adequate protective gear while inflating the tires.
  6. Never stand in the trajectory zone.

For more on using your air compressors for inflating your tires, feel free to call us on 022 43436655 or email us at marketing@vemc.co.in. VEMC is the leading ELGi dealer in Mumbai with a rich experience of over 70 years in the industry.

Air Compressor Noise Reduction: Strategies for Quieter Operation in Residential and Industrial Settings

While air compressors are a great source of power across industries and business facilities, these could often disturb the tranquility of a residential house. In these settings, it is necessary that the right strategies for noise-free operation are put in place. VEMC is the leading ELGi compressor dealer in Mumbai and in this blog, we tell you all about reducing the noise produced by your air compressor.

Understanding the sources of noise in air compressors

Before we take action against the noise, it is necessary to understand where it is coming from. The most common sources of noise in an air compressor are:

  1. Intake: The intake of air by a compressor can produce noise due to shifts in pressure or turbulent torrents entering your air compressor.
  2. Discharge: Just as air entering your compressor forcefully produces noise, the compressed air pushed out through the discharge valve can also produce a significant amount of noise.
  3. Motor: Over a period of time, due to friction, wear and tear, or lack of lubrication, the motor of your air compressor can also start making noise.
  4. Vibration: An air compressor is a system of moving parts which can rub against each other during operations, creating a lot of vibration and noise. It may also be caused by simpler reasons like unsteady floor where the compressor rests.

Strategies for reducing air compressor noise

  1. Enclosures: If your compressor is producing noise beyond your tolerance levels, you can simply cut it off from the rest of your home or factory floor by building a physical enclosure around it. Soundproofing the walls of the enclosure can also go a long way in absorbing the noise.
  2. Silencers: Air compressor silencers or mufflers are effective devices available in the market which greatly help reduce the noise produced by an air compressor.
  3. Sound-absorbing material: Unlike steel or concrete, sound-absorbing material absorb rather than reflect the noise produced by a compressor. These include acoustic panels, foam or wood. 
  4. Proper installation location: Installing the compressor in a separate dedicated room can help prevent the noise from affecting the rest of the house or factory. Place the compressor away from walls and corners to prevent the noise from rebounding and amplifying.

Regulations and standards for noise levels

Noise pollution is a massive concern when you’re investing in an air compressor for your home or factory. When buying a compressor in India, you must be aware of the regulations and standards set as per the Noise Pollution (Regulation & Control) Rules, 2000. Here are the noise levels acceptable in various settings as per the rules:

Area codeCategory of Area / ZoneLimits in dB(A) Leq
Day TimeNight Time
(A)Industrial area7570
(B)Commercial area6555
(C)Residential area5545
(D)Silence Zone5040

Understanding Air Compressor Duty Cycle

by vemcoblogs -

Table of Content

Understanding Air Compressor Duty Cycle

If you plan to procure a new air compressor, you will inevitably come across a specification called Duty Cycle in percentage terms. While a 100% duty cycle may be emphatically advertised by a seller and even seem alluring, you will require a more nuanced and in-depth understanding of the concept. VEMC is one of the leading ELGi air compressor dealers in Mumbai and in this blog, we tell you all you need to know about air compressor duty cycles.

Defining a Duty Cycle

The duty cycle of an air compressor simply refers to the time taken to fill its air tank. Every time the tank of an air compressor is full, the pump stops and then starts again. This is known as the run-time versus rest time of a compressor. However, in case a compressor doesn’t have a tank, then its duty cycle will always be 100%.

A compressor with 25% duty cycle means the compressor will have 45 minutes of downtime every hour and be active for only 15 minutes. Likewise, for a compressor with 50% duty cycle will have a downtime for 30 minutes and be active for 30 minutes.

Factors influencing duty cycle selection

  • Air demand: If your air demand is high, you will require an air compressor with longer duty cycle.
  • System size: A larger system will require a longer duty cycle and vice versa.
  • Pressure requirements: Duty cycle also depends upon the pressure required for your task. This means more the pressure required, more should be the duty cycle.

Selecting the right compressor based on duty cycle

Air compressor with intermittent duty cycles

Applications like filling a tyre, powering mechanical tools like wrenches and nailers, or DIY home projects can make use of compressors with intermittent duty cycles.

Air compressor with continuous duty cycles

Applications like powering tools in electronics, furniture and automobile industries, and operating conveyor belt systems use compressors with continuous duty cycles.

A duty cycle can be a critical determining factor when it comes to selecting the right compressor. However, you must be mindful of a few considerations.

  • Avoiding overloading: While it may be quite tempting to select a compressor with highest possible duty cycle, over-cycling can be problematic. Over-cycling could seriously impact the health of your system and reduce its lifespan significantly due to wear and tear. It also reduces the efficiency of the system as quick cycling consumes more energy.
  • Ensuring sufficient capacity for peak demand: When the demand of compressed air is high, you must have adequate capacity to match it. You can use a larger storage tank or try a wide pressure band to ensure this.

Duty cycles are clearly a significant factor to determine the right air compressor type for the right task.

Compressed Air System Piping: Design Considerations for Pressure Drop Reduction

by vemcoblogs -

Compressed air is a major source of power in an industrial setting. But to get the most out of your air compressor system, you need to make sure all the ancillaries are well-designed and installed. Piping is an essential support system which plays a huge role in how well your compressed air system performs overall. We at VEMC are a top-notch ELGi dealer in Mumbai and in this blog, we tell you all you need to know about the design consideration of your piping to reduce the pressure drop in your air compressor system.

Factors contributing to pressure drop in piping

  1. Pipe diameter: This is one of the most obvious factors that impacts the pressure of the compressed air in the piping. Pipe diameter impacts the velocity of the air moving through the pipes. To put it simply, larger the pipe diameter, lesser will be the pressure for a given volume of air.
  2. Length of the pipe: Longer the pipe, greater will be the friction loss and hence lesser will be the pressure exerted by the compressed air. Pressure drop is thus directly proportional to the pipe length.
  3. Material: The friction that the moving air particles experience against the walls of the piping also contributes significantly to the drop in pressure. Thus, the material of the piping walls will also determine the extent of pressure drop.
  4. Fittings: How the piping is designed and fitted is an important factor that affects the drop in pressure. A highly complicated design with too many bends will reduce greater amount of air pressure as compared to a more straightforward one.

Strategies to minimise pressure drop

Now that we have understood what factors cause drop in pressure, let’s take a look at how to avoid or at least minimise it.

  1. Appropriate pipe sizing: Make sure the pipes are of the right size in terms of both length and diameter. Both long as well as broad pipes can cause unnecessary drop in pressure.
  2. Avoid unnecessary bends and restrictions: As much as possible, the piping design should be simple and straightforward. Too many bends and restrictions can also cause a drop in pressure due to greater friction.
  3. Use smooth-surfaced pipes: As mentioned above, friction of air particles with the internal surface of the pipes can also reduce the pressure of the compressed air. It is therefore advisable to use smooth-surfaced material for your piping.

It is quite clear that not only does the power and capacity of your air compressor matter but also the overall system and piping design. With the right piping design and installation, you can maintain optimum performance by reducing drop in pressure.

Understanding Air Compressor Discharge Pressure

by vemcoblogs -

If you’re an air compressor owner, you must be acquainted with some of the basics of your equipment. Discharge pressure is one of the most relevant notions that significantly impacts how your air compressor performs. VEMC is one of the leading air compressor dealers in Mumbai, and in this blog, we take you through all you need to know about discharge pressure.

Definition and importance of discharge pressure

Discharge pressure simply refers to the air pressure at the output end, that is, the discharge flange of your compressor. Maintaining optimum discharge pressure is necessary to ensure maximum levels of efficiency and productivity. However, higher than required discharge pressure could cause wastage of energy as well as damage to the system. This is because of the rise in temperature leading to metal fatigue of valves and thermal stress on lubricants.

Factors affecting discharge pressure

Discharge pressure of an air compressor is quite dynamic and a number of factors affect it. Some of these are:

  1. Size and speed of the condenser fan
  2. Size of the discharge line
  3. Condition of the condenser coil
  4. Leakage of air
  5. Cooling effect by oil, water , etc.
  6. Rotational speed in case of a screw compressor
  7. Voltage and frequency of the power grid
  8. Suction temperature and pressure

Impact of discharge pressure on system performance and efficiency

For starters, discharge pressure directly impacts the air flow of a compressor, and the simple Boyle’s Law equation can substantiate this. 

P1 x V1 = P2 x V2

However, compressed air isn’t free and with every unit rise in discharge pressure, there is a proportionate rise in energy consumption as well. In fact, it is widely believed that for every 2-psi increase in pressure, the energy consumption increases by 1 percent. So while increase in discharge pressure does boost your performance significantly, it also reduces the efficiency due to overconsumption of energy. Besides, higher levels of discharge pressure can also cause leaks in the system and reduce the distribution of the compressed air, while reducing the lifespan of the air compressor in the long run.

Optimal discharge pressure settings for different applications

It is quite clear that operating an air compressor and deciding the right discharge pressure requires  some amount of nuance. There is no on-size-fits-all for every application that you use your compressor for. Industrial applications usually require a pressure of 100-200 psi while if you’re using the compressor for domestic use, anything between 90-150 psi should be enough. Pneumatic tools like nail guns require a pressure of 90-100 psi while sandblasters and spray painters would typically need 120-150 psi.

Discharge pressure seems to be a straightforward notion. However, to ensure you get the maximum out of your air compressor without wasting energy, you must operate it at the right levels of discharge pressure.

Air Compressor Dryers: Why They are Essential and How to Choose One

by vemcoblogs -

Air compressors find use in a number of industrial applications such as spray painting, packaging and drilling. But a common issue in air compressors is the accumulation of moisture which could be problematic for a number of reasons. This issue can be dealt with using the right kind of air dryer. VEMC is one of the leading air compressor dealers in Mumbai and in this blog, we tell you everything you need to know about air compressor dryers.

Why moisture in air compressors is problematic

Condensation of humidity inside an air compressor is a common issue and can appear in pipes, filters and other machinery. This can cause malfunction and breakdown of the equipment using the compressed air. Over the longer time horizon, it can be a cause for corrosion in the metallic parts. It is especially worrying if you are using the air compressor in packaging as the moisture can lead to the growth of moulds and cause spoilage of packaged items. To get rid of the moisture, air compressor dryers are essential accessories for your equipment.

Types of air dryers

Air compressors dryers are available in a number of variants each suited for a certain set of operations:

  1. Refrigerated air dryers: 

These air dryers condense the moisture in the air to very low temperatures, thus removing it and allowing the compressed air to proceed ahead to the attached tool.  These are available in cycling and non-cycling variants. The former supply variable cooling to match the demand while the latter supply constant cooling irrespective of the demand. Refrigerated air dryers are best suited for manufacturing and service applications but not for highly sensitive ones where even a little moisture can be problematic.

  1. Desiccant air dryers: 

These operate by desiccating the air using hygroscopic materials like silica gel or activated alumina. A twin-tower drying system is typically used both chambers of which contain desiccant materials. These air dryers are best suited for moisture-sensitive industrial applications such as healthcare, packaging, fabric manufacturing , etc.

  1. Membrane air dryers: 

These use specialised membranes to filter moisture out of the compressed air. The microtubules present in the membrane retain water while the dried air is allowed to pass through to the required application. These types of air dryers are best suited for applications such as food processing, dehumidification and gas separation. 

Choosing the right air dryer

Your choice of air dryer depends upon your specific needs as listed above and also your budget. For standardised functions, say in manufacturing, cost-effective air compressors like non-cyclic refrigerators are good enough. However, if your business applications are extremely moisture-sensitive, it is best to use slightly more expensive but highly effective desiccant air dryers.

The ABCs of Air Compressor Accessories

by vemcoblogs -

Air compressors are the go-to equipment to generate power for a number of tasks in industrial as well as domestic settings. These include spray painting, drilling, cleaning etc. However, air compressors can offer optimum performance only when the accessories are functioning well. VEMC is the leading air compressor supplier in Mumbai, and in this blog, we acquaint you with the ABCs of air compressor accessories.

Types of accessories

  1. Filters: 

Air compressor filters are important to remove dust and debris and push out only clean compressed air. Their role is even more important in case you are using your air compressor in sensitive work environments like food processing. Rotary screw air compressors have three filters: an oil filter, an inlet filter and air/oil separator. While on an average, filters must be replaced every 2000 hours of service, they may need even more frequent replacement in dirtier conditions. Replacement helps prevent the oil from becoming contaminated and also the premature failure of the parts.

  1. Regulators: 

Air compressor regulators help control the air pressure in a pneumatic system. This ensures that the air compressor operates safely and at optimum levels of efficiency. 

  • General purpose regulators: These are best suited for use in industrial settings and operate above the atmospheric pressure.
  • High pressure regulators: These have an inlet pressure of 1000 psi.
  • Dual stage regulators: In these regulators, the liquid flows through a succession of chambers to deliver constant pressure.
  • Point-of-use regulators: These regulators are attached at or near a tool such as a pneumatic drill.

3. Lubricators: 

Air compressor lubricators help reduce friction between parts of an air compressor and dissipate the extra heat generated. An air compressor lubrication system comprises of a crankcase sump, strainer, filter and cylinder lubricator. The lubricating oil is contained in the compressor crankcase. A preset mark on the crankcase indicates the level of lubricating oil that must be present in it and thus helps at the time of replenishment. 

4. Valves: 

Air compressor valves control the in and out-flow of air or oil in a compressor.

  • Intake valve: As the name suggests, an intake valve enables the air to enter the compressor. This air is then directed to the compressor head where it is compressed.
  • Minimum pressure valve: It is located at the outlet above the oil-gas separator. It acts as a buffer to control the flow rate of the gas and prevent damage due to high-speed airflow.
  • Safety valve: This is important for the safety of the air compressor as it discharges some gas as soon as the pressure exceeds a certain level.

Choosing the right accessories

If you are looking for accessories for your air compressor, make sure you only choose the original ones. Only original accessories can guarantee optimum performance and a long service life.

Top 5 Tips to Elevate your Air Compressor’s Productivity

by vemcoblogs -

An air compressor is one of the most useful equipment both at home and in the industry. It uses the power of compressed air to perform wide ranging tasks such as drilling, inflating tyres, refrigeration, air conditioning and spray painting. As an air compressor owner, you would like to get the maximum out of your equipment with the consumption of minimum possible energy.

VEMC is one of the leading air compressor dealers in Mumbai, and in this blog, we share 5 tips that will help you elevate your compressor’s productivity significantly.

Conduct air checks regularly

When using an air compressor, carry out regular air checks as part of routine maintenance and inspection process. With the help of a data recording device, you can take precise readings without obstructing the operations. The air check shows the pressure and volume, thus ensuring optimised use and minimum possible energy consumption.

Recover the dissipated heat

A substantial portion of energy that is generated by an air compressor is lost in the form of heat. This accounts for up to 90% of the energy. By making use of this dissipated heat in warming your facility or heating water, you can avoid wastage of this significant amount of energy which is anyway released by your compressor.

Plug leakages

Air leakage can cause a significant amount of leakage and must therefore be frequently inspected and plugged. Apart from the compressor piping, make sure valves, couplings and flanges are properly checked for leaks. You may need a qualified and experienced service-provider such as VEMC –– a top air compressor dealer in Mumbai, for this. 

Stop off-load running

No-load running of your air compressor is another problem area. It consumes energy while not producing any compressed air. Besides, when the compressor is stopped and restarted, it causes extra wear and tear, leading to higher maintenance costs. To ensure the system is suitably configured, proper sizing of the system or having an intelligent control system in place is necessary.

Use only genuine spares

Long service life and efficiency in operations can be guaranteed only by original spare parts. This doesn’t just apply to the valves, seals and compressor stages, but also to lubricants. Original spare parts are manufactured keeping in close view the design and configuration of the air compressor. The same cannot be said of non-genuine spare parts which may seem marginally cheaper but may end up costing much higher in the long run due to low efficiency, more wear and tear, and higher maintenance costs.

If you are an air compressor owner, you must look for possible areas of poor efficiency and wastage of energy, and take suitable corrective measures. For more information on how to prevent wastage and ensure your air compressors run at maximum efficiency, feel free to get in touch with our experts by calling us on 022 43436655 or emailing us at marketing@vemc.co.in.

The Role of Pumps and Air Compressors in the Circular Economy

by vemcoblogs -

As opposed to a linear economy which proceeds through the stages of ‘take-make-waste’, a circular economy is restorative and regenerative. The economic activity in a circular economy builds and rebuilds the overall health of the system. It aims at decoupling growth from the consumption of finite resources. The three most significant features of a circular economy are resource efficiency, waste reduction and closed-loop systems. A circular economy offers enduring benefits like environmental sustainability, economic growth and job creation.

VEMC is the leading air compressor dealer in Mumbai, and in this blog we take you through the role of pumps and air compressors in a circular economy.

Industries that rely on pumps and air compressors

A range of industries such as manufacturing, wastewater treatment and energy production rely on water pumps and air compressors. Here are some of the major functions performed by them:

By pumps:

  1. Transporting fluids such as chemicals, oil, water etc. from one place to another
  2. Removing pollutants and contaminants from fluids
  3. Providing the necessary pressure required for industrial processes
  4. Mixing and blending liquids

By air compressors:

  1. Pushing and propelling gases through pipelines
  2. Blow cleaning and spray painting operations
  3. Powering pneumatic tools such as drills, abrasive blast equipment etc.
  4. Shifting AC refrigerants

All the above-mentioned functions consume energy. To create and sustain a circular economy, it is important that energy efficient pumps and compressors are used, so that operations are performed at peak levels without wastage of energy.

Recycling and remanufacturing pumps and air compressors

Air compressors and pumps that are in use for a very long time will inevitably undergo wear and tear. This will affect their performance and energy efficiency. However, if these equipment are procured from trusted manufacturers like VEMC, you can expect longevity and consistent performance. This is not just great for your business as it avoids sudden breakdowns, loss of business and unexpected capex investments, but also for the circular economy as it avoids wastage of resources and lowers the carbon footprint. Besides, techniques like retrofitting can offer a second life to your equipment while enhancing their performance and efficiency.

Role of compressors and pumps in a circular economy

One of the most important aims of a circular economy is to reduce wastage and lifespan costs of equipment. This is ensured in three main ways:

  • Products like compressors and pumps which are designed keeping the concept of circular economy in mind, aim to extract maximum value out of resources. As soon as the products reach the end of their service life, their parts are salvaged and re-processed to leave as little waste as possible. 
  • Product design also ensures that as little wastage of material during operations (through friction) takes place. The simplicity of design to avoid as much metal-to-metal contact can help reduce lifetime costs of the equipment significantly. 
  • The product designs also ensure minimal consumption of energy and enhanced operational efficiency. This contributes to lower carbon footprint and energy savings throughout the service life of the product.
