Improved Efficiency
AMSOIL PC Series Synthetic Compressor Oil reduces friction and resists viscosity increase from oxidation to help improve operating efficiency.
Controls Foam and Reduces Wear
AMSOIL PC Series Synthetic Compressor Oil contains anti-foam and anti-wear additives to reduce heat, oxidation and wear for increased oil and compressor life and lower maintenance costs.
Resists Water Contamination
Condensation causes unwanted oil/water emulsions that lead to rust and corrosion. AMSOIL PC Series Synthetic Compressor Oil is anti-rust fortified and hydrolytically stable. It readily separates from water for easy drainage and increased oil life.
Superior Varnish Resistance
Varnish is a major problem in high-temperature compressor applications, reducing efficiency and causing mechanical breakdowns. A leading competitor compressor oil and AMSOIL PC Series Synthetic Compressor Oil (PCI) were run in industrial rotary-screw compressors with a 200°F oil discharge temperature and compared using the Membrane Patch Colorimetry Test (ASTM D7843).
The competing oil showed critical varnish potential after only 6,228 hours of service. AMSOIL PC Series continued to show ultra-low varnish potential after 8,000 hours, indicating superior resistance to varnish.
Resists Heat and Oxidation
AMSOIL PC Series Synthetic Compressor Oil combines the inherent stability of premium synthetic base oils with specialized antioxidant additives to resist varnish, carbon and acid formation. It protects compressors better and lasts longer in service than petroleum oils, especially at high temperatures.
Safety Advantage
AMSOIL PC Series Synthetic Compressor Oil is an ashless, high-flash-point formulation with very low carbon-forming tendencies that minimizes ignition-promoting “hot spots.” While it can provide improved fire safety, it is not a fire-resistant oil.
Reduced Oil Consumption
Excessive oil consumption requires frequent top-offs, wasting time and money. A leading competitor synthetic compressor oil and AMSOIL PC Series Synthetic Compressor Oil (PCI) were each run for 8,000 hours in an industrial rotary-screw compressor under the same operating conditions.
The excellent foam resistance and air-release properties of AMSOIL PC Series Synthetic Compressor Oil helped reduce oil consumption 35%.
APPLICATIONS
Use the appropriate viscosity of AMSOIL PC Series Synthetic Compressor Oil in single and multistage rotary screw, vane, centrifugal and reciprocating compressor crankcases and cylinders, vacuum pumps, pressure washer pumps and other applications such as gears, bearings, blowers and pumps.
Drain intervals of up to 8,000 hours can be expected under normal operation in rotary screw compressors, subject to operating conditions and maintenance practices. Monitoring by oil analysis is recommended. Consult the equipment manufacturer or AMSOIL Technical Services for specific application info.
COMPATIBILITY
AMSOIL PC Series Synthetic Compressor Oil is compatible with petroleum oils and most synthetic oils, seals, paints and materials. For best performance, flush the compressor of old oil, remove any carbon deposits present on internal components following the compressor manufacturer recommendations and change all filters prior to installation.
Not recommended for “breathing air” or refrigeration compressors or for use with polycarbonate or PVC plastics and butyl, ethylene-propylene or SBR rubber.
Not compatible with polyalkylene glycol or silicone oils.
