CPI 4100 Series Air Compressor Oils are manufactured with a high-quality diester base fluid, enhanced by an advanced anti-wear additive package. These oils provide exceptional thermal and oxidative stability, allowing them to function effectively across a broad temperature range without leading to varnish, sludge, or carbon deposits.

The CPI 4100 Series is also designed with extremely low volatility, reducing maintenance needs and significantly lowering lubricant consumption. Ideal for reciprocating compressors operating under high compression ratios and elevated temperatures, the CPI 4100 Series fluids are also well-suited for rotary vane and screw compressors, vacuum pumps, and other applications demanding a thermally and oxidatively stable lubricant.

Applications and Compressor Types:

Reciprocating compressors (crankcase and cylinder)

Rotary vane and screw compressors

Vacuum pumps

Other applications requiring thermal and oxidative stability
