ROYCO 889 is a synthetic-based lubricant formulated for use in gas compression applications that require wide operating temperature ranges and minimum interaction between the lubricant and the process gas.ROYCO 889 is intended for the lubrication of flooded rotary screw and vane-type compressors processing natural gas, carbon dioxide, or other hydrocarbon gases. ROYCO 889 may also be used as a cylinder lubricant for reciprocating compressors processing natural gas, carbon dioxide and other gases that require chemical resistance in an ISO 150 viscosity grade.
