When your process is exposed to oil, it becomes increasingly difficult to keep air clean, increasing the costs you'll face -- especially as you use more and more air. To address this concern, many companies are turning to oil-free or oil-less air compressors. Today, oil-free compressors are becoming more common because they offer cost savings.

These purity and environmental benefits will often translate into other savings that may reduce your overall ownership costs. Here are a few of the things to consider if you've been wondering: How do oil-free air compressors work? There's no need to collect or dispose of oil-ladened condensate. Downstream filters have reduced replacement needs, because they're not filtering oil. Energy costs are minimized because there's no need to increase force -- some fluid-flooded units can see a downstream pressure drop due to filtration. Reduced oil costs, because there's no need to continually refill your compressor. Typically, these units can unload within two seconds of the command to unload, and will use about 18% of their full load horsepower when unloaded. Those savings can be very tempting.

To see if you can make use of the oil-less compressors, you'll need an understanding of how the compressors work and in which applications they work best. Functional Steps of How Oil-Less Air Compressors Work.

Understanding how oil-free air compressors work and why they last as long as they do is best illustrated by reviewing each function in a step-by-step method. Let's walk through how a compressor starts working and provides you with the compressed air that you need. Oil-less air compressors start by bringing in outside air through their unloader valve and passing it through an inlet air filter (or filters) in order to ensure that the air is clean.

The filter will limit damage to your compressor and its internal components. These filters are typically fine enough that they keep out dust, dirt and small debris. The unloader valve opens to help the compressor pump air into its chamber, placing it in the "loaded" position.

When the valve closes, the compressor enters the "unloaded" condition and begins running. When your compressor is running and actively delivering compressed air, it typically won't be able to draw in any more air. When you turn on your compressor and it starts to draw in air through an open unloader valve, the first destination for the air is the low-pressure compressor element. You've probably noticed that your air compressor can create heat, and this often has to do with the low-pressure compressor element, because it's working without any oil.

The average compressor element will operate at around 2.5 bar, and compressing air alone can make the unit operate at a temperature of up to 180 degrees. That can be more than twice as high as the temperature that oil-lubricated compressors reach, due to the lack of a flowing medium that whisks away heat. Oil-free elements will begin compressing the air and then move it through your compressor to cool the air down so it can be used in your applications. After it's initially compressed, pistons will push the air through an intercooler, where the air can cool so it can be further compressed.

This will either move it to the second phase of compression or the final one, depending on the nature of your compressor. Compressing air generates heat that limits the oxygen content of the air, thus reducing its density. Cooling the air essentially acts as a simple method for allowing denser and more oxygen-rich air to be again used by the engine, which in turn provides more fuel and improves the power output when the air compressor is working with a combustion engine. Intercoolers are essential for two reasons.

First, they cool the air down to a proper temperature to minimize the risk of any damage related to heat. Second, intercoolers allow air to be compressed at much higher PSI's in two-stage pumps, and the cooling process means the second stage will face less wear. Cooling air can lead to some condensation, and intercoolers will come with standard filters designed to remove moisture and water from the air. You'll typically see this filter listed as a moisture trap. The air will move back into the main chamber of your air compressor -- or the second chamber, depending on its design -- and will be further compressed by a high-pressure element.

The maximum pressure you'll achieve typically ranges from 116 to 145 psig. The air again becomes very hot due to the lack of lubrication in the surrounding elements, so it will need to be cooled once more.

Air Prep and Aftercooler Access. During its second phase of compression, the air will reach temperatures of around 150 degrees, requiring additional cooling before it can be used in other equipment. The aftercooler is the destination for air after its final compression stages, and this cooling allows it to be properly stored. As air flows to the aftercooler, it will pass through a check valve that is designed to prevent any backflow, ensuring that air continues to compress and fill your tank.

Backflow will damage your equipment and cause a major failure of the air compressor. Many compressors -- especially reciprocating compressors -- are fitted with pulsation dampeners, and these are located just before the aftercooler. The dampener is designed to reduce pulsations and vibrations caused by the air compressor when it uses suction and opens discharge valves. Pulsations can reverberate through the piping system, and these vibrations will make it difficult for your tools and machinery to measure air pressure and use it properly. The air is finally stored or sent to your equipment for use.

Detection equipment in your air compressor tank will monitor the level of air you have. When it falls below a specified level, the air compressor will turn back on and start working to rebuild the pressurized air in the tank. The pressure switch is what is used to monitor and turn the compressor off and on. Pressure switches are typically attached to the unloader valve, though sometimes the valve is internal.

Pressure switches are set by the factory and arrive at predefined levels. The Oil in Oil-Free Air Compressors. When you think about how oil-less air compressors work, you'll need to realize that there is oil in the device, but that it won't come into contact with the compressor. There is oil in the gearbox of your oil-less air compressor. The gearbox of your air compressor is used to drive the two compressor elements via the electromotor. Gearboxes need lubrication to operate properly, and can be costly to replace, so maintenance checks should review them on a regular basis. The oil in your gearbox will lubricate the internal gears and bearings, as well as the bearing and timing gear located inside of each compressor element. Oil will be pumped from an oil sump inside the gearbox, and it's cooled via an oil cooler and oil filter before it is used to cool compressor or gearbox parts. The filters are used to remove debris during its action.

The main difference is that internal elements and parts of the gearbox will be treated with long-lasting lubrication. This puts more of a strain on the engine overtime, but requires less day-to-day maintenance. Understanding the general pressurization of air compressors is pretty straightforward and often operates the same across oil and oil-free units. For the oil-free compressors we're looking at, there are two main methods for cooling the compressor itself: Water and air.

Air-cooled compressors, which tend to be rotary screw compressors, use outside air to cool the compressed air and the oil used in the gearbox. Air circulates and moves heat away from internal components as well as from the parts that house the oil, which helps remove heat from your compressor elements. Water-cooled machines will have a two-part cooling system. Water moves near each element, heats up and flows away from the components, condenses and cools, and then moves back toward the equipment (often via gravity).

These systems will have a water-cooling circuit used for the oil, intercooler and low-pressure element. The second circuit works to cool the high-pressure element and the aftercooler.
