Compresyn HD PLD Series compressor oils are made from high-quality, shear-stable 100% synthetic base oils. They provide long compressor life through reduced component wear, corrosion protection, water resistance and lubricant breakdown resistance. This design helps reduce maintenance costs by extending drain intervals and lowering labor and used product disposal requirements. This multi-functional synthetic oil is recommended for use in single and multistage rotary screw, vane, centrifugal and reciprocating compressor crankcases and cylinders, vacuum pumps, and other compressor applications. It is highly resistant to rust and oxidation with drain intervals of over 8,000 hours in properly maintained equipment.
