Compressor & Vacuum Pump Lubricants
The PGWS Series of synthetic oils are polyglycol-based for use in compressors, vacuum pumps, enclosed gears, bearings, and other applications where the unique properties of these fluids are necessary. The use of the PGWS oils in gas compression preserves the unique viscosity-temperature relationships of these unique products by resisting thinning out by hydrocarbon dilution. Contact your Ultrachem representative for specific recommendations, due to the variability of gases and pressures involved in these applications.
Characteristics
- Resists hydrocarbon washout/dilution.
- Extended drain life.
- Reduced sludge and deposit formation.
- Excellent oxidative and thermal stability.
- Not compatible with petroleum oils and synthetic hydrocarbons.
