ROYCO® 889 Synthetic Compressor Lubricant
ROYCO® 889 synthetic compressor lubricant is designed to be used in gas compression applications within a wide temperature range, where a key requirement is minimal interaction with the process gas. ROYCO 889 lubricates vane-type and flooded rotary screw compressors that process carbon dioxide, natural gas, and other hydrocarbon gases. It can also be used as a cylinder lubricant. It has an ISO viscosity grade of 150 for chemical resistance. See the ROYCO 889 safety data sheet (SDS) on this page.
- Recommended: Acetone, Alcohol, Asbestos, Butyl Dioxtol, Chlorinated Solvents, Glycol Ether, Neoprene, Epoxy Paint, Silicone Rubber, Toluene, Torlon (AMOCO), Vespal (DuPont), and Viton (DuPont).
- Questionable: Ethylene Glycol, Triethanolamine, and Water.
- Not Recommended: Gasoline, Glycerol, Heptane, Kerosene, Leather, Methanol, and Oil-based paint.
FeaturesResists wash off by hydrocarbon gases and liquidsResists absorption into the gas phase and carry-over of the lubricant downstreamMinimizes dilution effects due to insolubility of the lubricant with hydrocarbonsHigher film-strength that traditional lubricantsProtects against corrosionFully compatible with most compressor component materials, including: seals, gaskets, hoses, etc.
