Applications:
The PGWS series fluids are full synthetic lubricants formulated with premium polyalkylene glycol (PAG) base oils. The PGWS lubricants are designed for use in compressors, vacuum pumps, enclosed gears, bearings, and other applications where unique properties of these fluids are necessary. The use of the PGWS oils in gas compression preserves the unique viscosity-temperature relationships of these premium products by resisting thinning out by hydrocarbon dilution. PGWS lubricants yield a compressor service life of 8,000 – 10,000 hours under good operating conditions.
Typical Industrial Applications:
Rotary Screw Compressors, Rotary Vane Compressors, Centrifugal Compressors, Reciprocating Compressors, Vacuum Pumps, Enclosed gears and bearings.
Performance Benefits:
Resists hydrocarbon washout/dilution, Extended drain life, Reduced sludge and deposit formation, Excellent oxidative and thermal stability.
