HYCOM PGE Air compressor lubricants have been specially designed for use in rotary screw air compressors. HYCOM PGE compressor lubricants are a fully formulated, fully synthetic blend of polyalkylene glycol (PAG) and polyol ester and thus, take advantage of the excellent performance attributes of both classes of compound. In addition, due to the inherently high viscosity index of HYCOM PGE lubricants, no additional VI improvers are required in the formulation and so the products remain stable to shear forces and do not suffer any irreversible effects.
