AMSOIL PC Series Synthetic Compressor Oils

Product Code: PCH, PCI, PCJ, PCK, PCL

Synthetic PC Series Compressor Oil

A HE CORRECT MANUFACTURER-RECOMMENDED VISCOSITY GRADE of AMSOIL PC Series compressor oil is recommended for use in rotary screw, rotary vane, reciprocating and other compressor applications. Compatible with PAO-, ester- and petroleum-based compressor oils. They are not compatible with glycol- or silicone-based compressor oils. Consult AMSOIL for further information.

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.

AMSOIL Synthetic Base Oil Technology

AMSOIL’s unique formulation of synthetic base oils combine the advantages of esters and polyalphaolefins (PAO's) into one balanced product. The high viscosity indices, low pour points, low volatility and prolonged thermal stability allow for use in a wide operating temperature range. These oils minimize carbon build-up, provide clean performance and exhibit low frictional characteristics. This superior formulation has demonstrated increased operational efficiency, reduced energy consumption and lower operating temperatures.

AMSOIL Compressor Oil Additives - A Thorough System for Top Performance

The anti-foam agents stop unwanted foaming and air entrainment. Corrosion inhibitors prevent rust and corrosion caused by water and process contaminants, and oxidation inhibitors extend lubricant life and prevent carbon formation. The PC Series is fortified with ashless, non-detergent additives designed to increase the length of compressor serviceability.

Stable in the Presence of Water

AMSOIL PC Series exhibit very good hydrolytic stability, and they readily separate from water. This prevents acid formation and unwanted oil/water emulsions. These features allow water to be easily drained from the sump and extends the life of a lubricant.

Safety Advantage

AMSOIL PC Series Compressor Oils have higher flash, fire and auto-ignition points than competitive petroleum oils. Also, their resistance to carbon formation and the ashless additive system minimize the incidence of deposits acting as ignition-promoting hot spots. Although AMSOIL PC Series Compressor Oils have high fire points, they cannot be considered non-flammable.

  • Anti-foam, anti-wear protection
  • Rust and oxidation inhibited
  • Suitable for use in rotary screw, vane, centrifugal and reciprocating compressors
  • Combines advantages of ester and PAO technology
  • Excellent compatibility with components and other oils

The manufacturer's recommended viscosity grade of AMSOIL PC Series Oils is recommended for use in single and multi-stage rotary screw, vane, centrifugal and reciprocating compressor crankcases and cylinders, vacuum pumps and other compressor applications. In addition, the correct viscosity may be used in light duty gear and bearing applications, blowers, pumps and hand-held pneumatic tools. 

  • PC Series Synthetic Compressor Oils are recommended for use in a wide temperature range, from 20F above the pour point to 275F discharge temperature.
  • The PC Series may be used up to 8000 hours for many compressor applications.* This drain interval is subject to operating conditions and maintenance practices. Monitoring by oil analysis at 500-hour intervals is recommended.
  • PC Oils are compatible with petroleum oils, most synthetic oils,** and almost all seals, paints and materials commonly used in compressors. It is suggested that the compressor be thoroughly drained and cleaned if warranted, and the filter be changed prior to filling with the new lubricant. Cleaning should be done in accordance with manufacturer's recommendations. Consult AMSOIL technical department where further recommendations are needed.
