Syndustrial Rotary Compressor Oil is a premium quality synthetic lubricant developed for use in oil-flooded rotary screw, rotary lobe and rotary vane air compressors. It is particularly recommended for use in applications where operating conditions are unfavorable or too severe for conventional mineral oil-based compressor oils.

Syndustrial Rotary Compressor Oil is available in two intermediate viscosity grades: ISO 32/46 and 46/68. It is formulated with a blend of synthetic polyalkylene glycol (PAG) and synthetic ester base oils and carefully selected additives. It has outstanding oxidation resistance and thermal stability at high temperatures to help minimize deposit formation and provide long service life. It has high film strength to protect against wear, and also protects against rust and corrosion.

Syndustrial Rotary Compressor Oil is formulated to outperform conventional paraffinic or naphthenic compressor oils in oxidation resistance and deposit control. It has better thermal stability at high temperatures to minimize the buildup of sludge and varnish. It also has lower volatility for lower oil consumption. These benefits result in longer service intervals and less maintenance than with petroleum oils.

Note: Syndustrial Rotary Compressor Oil is not compatible with petroleum compressor oils. Care should be taken to avoid mixing the two products. When switching over from mineral oil to Syndustrial Rotary Compressor Oil, a complete flush, drain and refill should be performed.
