How do I Choose an oil-free air compressor?

The first step in selecting any compressor is assessing your facility’s needs. There are instances where the consequences of oil contamination are too high, therefore having an oil-free air compressor is a must.

Why is oil free air compressor better than oil lubricated air compressors?

Since there is no lubricating oil splashing inside the compressor, the air is drier and much cleaner. Instead, oil-free compressors utilize non-friction coatings (such as Teflon) on the surface of moving parts to reduce friction. Oil-free air compressors require a lot less maintenance than their oil-lubricated counterparts.

Do oil-free air compressors use oil?

Oil-free air compressors do not use oil for compression. However, oil is used in other parts of the compressor, such as for cooling and lubrication. Sealing systems are integrated into the compressor to prevent oil from entering the compressed air system.

Are oil-free air compressors worth it?

But with oil-free compressors, the parts are made differently so they don’t need oil to run. And because of that, they don’t need to be serviced as often. So, in a nutshell, oil-free compressors = no oil, less maintenance. Got it? Cool. Let’s first discuss what are the advantages of getting an oil free air compressor:

How do I choose the best air compressor?

The first step in selecting any air compressor is assessing your facility's needs. The majority of manufacturing, industrial, and small workshops utilize oil injected compressors. With these machines, oil is used to lubricate, seal, and cool compressed air. Due to this process, slight oil contamination occurs in air delivery.

What type of oil does an air compressor use?

The vast majority of air compressors are the oil-lubricated type. Most oil air compressors used this added oil in a function known as splash lubrication. The oil added flows into an oil sump, from which a dipper on the piston rod dips into the oil in the sump and splashes it onto the moving parts as the piston moves.
