Large lubricated air compressor

The Titus Company offers a wide range of air compressors to meet the different needs of various industries and companies. One choice you can make when deciding on an air compressor is whether you want a lubricated air compressor or an oil-free air compressor. What is the difference between the two, and which is right for you and your business?

What Is a Lubricated Air Compressor?

The general mechanism of an air compressor is a piston or rotary element (e.g. rotary screw or vane) that draws in air, which is compressed into a storage tank. Naturally, since the piston or rotary element needs to move consistently and smoothly for this to work, it generally needs to be lubricated.

In a lubricated air compressor, there is lubricating oil which keeps the piston or rotary element running smoothly without damaging the mechanism. The lubricant also helps to dissipate heat and maintain air compression efficiency.

What Is an Oil-Free Air Compressor?

Oil-free air compressors also use a piston or rotary element, but they get around the lubrication problem by coating the compression element with a pre-lubricating material like Teflon. Some oil-free compressors may also use water in place of oil for the lubricating and cooling process. These alternate materials protect the pump and allow the mechanism to move smoothly without the need for any oil-based or synthetic lubrication.


What Are the Differences Between Lubricated and Oil-Free Air Compressors?

There are several differences between lubricated and oil-free air compressors, beyond the presence or absence of oil. Lubricated air compressors require more routine maintenance. Specifically, you have to change the oil every now and then. Lubricated air compressors also require more air filtration such as separators & coalescing filters to remove the oil and protect downstream equipment and processes from contamination.

However, in comparison to lubricated compressors, oil-free varieties require more major repair work and don’t tend to last as long. They can also be much louder in operation.

For this reason, when you are in an industrial environment where your air compressors are getting heavy use, lubricated compressors are often a better choice. If you’re in an industry that requires very high purity air, however, such as pharmaceutical, food processing or electronics, you may want to opt for the oil-free version.
