GPL Ester is a full synthetic ester-based gas compressor lubricant that has been formulated for use in air and gas compressors with high discharge temperatures. GPL Ester is a highly stable formulation and will resist degradation and oxidation even at extremely high temperatures. GPL Ester offers excellent resistance against carbon and varnish formation and and will continue to combat carbon and varnish buildup throughout the life of the oil.
The excellent cleaning capabilities of GPL Ester make it the ideal lubricant for co-generation applications (methane recovery)
