Compressor Oil Cross Reference Guide

Product Description
AMSOIL PC Series Synthetic Compressor Oils are longlife, premium compressor lubricants based on novel, proprietary technology. They incorporate the highest quality, thermally-stable PAO synthetics fortified with premium non-detergent, ashless additives for maximum protection at high temperatures and pressures. They last up to eight times longer than petroleum oils, effectively reducing maintenance and waste oil disposal costs.

Improves Compressor Efficiency
AMSOIL PC Synthetic Compressor Oils have low friction properties and they resist viscosity increase from oxidation. They help improve operating efficiency and save money on electrical energy consumption.

Controls Foam and Reduces Wear
AMSOIL PC Compressor Oils contain anti-foam additives and, unlike other compressor oils, they are anti-wear fortified. Good foam control reduces heat, oxidation and wear. High contact regions are protected against wear for increased compressor life and efficiency.

Resists Water Contamination
Water from condensation builds up in compressors that can cause unwanted oil/water emulsions, environmental discharge hazards and rust. AMSOIL PC Synthetic Compressor Oils are hydrolytically stable. They resist acid formation, readily separate from water and are anti-rust fortified. Water can be easily drained off for simplified environmental discharge and increased oil life.

Resists Heat and Oxidation
AMSOIL PC Series Compressor Oils combine the inherent stability of premium synthetic base oils with specialized anti-oxidant additives to resist varnish, carbon and acid formation. They protect compressors better and last longer in service than petroleum oils, especially during hot operating conditions.

Safety Advantage
AMSOIL PC Series Synthetic Compressor Oils are ashless, high flash point formulations with very low carbonforming tendencies that minimize the incidence of ignition-promoting “hot spots.” While PC Synthetic Compressor Oils can provide improved fire safety, they cannot be considered non-flammable.

Application Recommendation
The appropriate viscosity of AMSOIL PC Series Synthetic Compressor Oil is recommended for use in single and multistage rotary screw, vane, centrifugal and reciprocating compressor crankcase and cylinders, vacuum pumps and other applications such as gears, bearings, blowers, pumps and handheld pneumatic tools. In compressor applications, drain intervals of 8,000 hours or more can be expected under normal operation. Drain intervals are subject to operating conditions and maintenance practices. Monitoring by oil analysis is recommended. For best performance, AMSOIL recommends the compressor be drained prior to the installation of PC Synthetic Compressor Oil. If carbon deposits are present on the internal components, it is recommended they be removed following the compressor manufacturer recommendations.
