Rotary Screw Compressor Lubricants

The CPGRS & CPGRI products have excellent separation capabilities allowing the use of the industry standard float type Oil / Water condensate separators.

SILICONE SERIES: COMPSIL
COMPSILl is a super premium synthetic silicone compressor fluid designed specifically for replacement of OEM silicone fluids. It is completely compatible with these fluids and can be mixed in any ratio. COMPSIL is formulated with the Complete advanced technology additive system for improved anti-corrosion performance. It protects against oxidation, wear, rust, and corrosion. COMPSIL provides extremely long fluid life in machines requiring this type of fluid.

Series 7 lubricants are blended from several synthetic base stocks, have the Complete advanced technology additive system, and provide outstanding performance. Series 7 lubricants combine the best characteristics of these base stocks to form a synergistic blend of fluids and additive systems. These lubricants are extremely high quality replacements for many OEM lubricants in rotary screw compressors.


PGR compressor lubricants are 100% synthetic non-glycol replacement fluids for polyglycols. Polyglycols (also called PAG's or polyalkylene glycols) are supplied as OEM compressor fluids in many compressors.

The PGR series products have good biodegradability and are environmentally neutral. They also exhibit much better oxidation and thermal stability, longer fluid life and mix perfectly with polyglycols. This ability to mix with PAG's means flushing of compressors is not necessary to change to Amerilube PGR's. This provides the added benefit of allowing topping off of compressors containing Polyglycol fluids until scheduled change intervals.
