Premium Rotary Air Compressor Oil

PremiumSynthetic Blend Lubricant

Phillips 66®Premium Rotary Air Compressor Oil is a premium quality, part-synthetic lubricant developed for use in rotary air compressors operating under moderate to severe service conditions. The part-synthetic formulation provides enhanced thermal and oxidative stability at high temperatures to minimize the formation of sludge and varnish.

Features & Benefits

• Part-synthetic formulation for enhanced performance benefits

• Excellent resistance to thermal breakdown at high temperatures

• Excellent oxidation resistance to minimize sludge and varnish formation

• Good wear protection

• Natural detergency

• Protects against rust and corrosion

• Good low-temperature properties

• Good water-separating properties

• Good foam resistance

• Low carbon-forming tendency


• Oil-flooded rotary screw, rotary lobe, and rotary vane air compressors

• Circulating systems requiring a part-synthetic lubricant

• Industrial equipment operating over a wide temperature range where an inhibited mineral oil is recommended

• Industrial equipment where operating conditions are too severe for conventional mineral oil based R&O-inhibited circulating oils
