Screw Air Compressor Oil

The most common lubricants used for industrial air compressors. Paos are derived from ethylene (from natural gas or petroleum). They are engineered for high stability, low volatility and uniform flow across a wide temperature range. This is a good multi-purpose air compressor oil.

The second most common air compressor lubricant. They are derived from an alcohol and carboxylic acid rather than petroleum sources. They offer outstanding thermal stability, excellent longevity and mix readily with other additives and lubricant stocks. Poes also act as dispersants, which can help keep lubricated parts clean.

Another group of non-petroleum synthetic lubricants. Their chief advantage is that, unlike most air compressor oils, they do not oxidize to create “varnish” on the inside of the air compressor. (more on varnish below.)

Many air compressors use a blend of poa and mineral oils. This is a more cost-effective alternative to a pure poa base. Blends are often used for applications that require frequent oil changes (for example, environments in which oil is contaminated quickly by particulates at the air inlet).

Food-grade air compressor oils are synthetic oils that are non-toxic and appropriate for use in applications where compressed air May come in contact with food, such as food packaging lines.
