These are the finest high-performance, synthetic diester fluids available for lubricating all types of compressors. They offer extended drain intervals many times longer than the best mineral-based fluids. They also extend compressor life and reduce routine maintenance of the compressor. They leave minimum deposits on valves of reciprocating compressors, and have excellent antiwear properties. JAX Syncomp-D fluids are especially effective in sliding vane and rotating screw compressors operating under severe conditions.
