Compressor / Refrigeration Oils

For every 18 F above the maximum discharge temperature listed, the expected lubricant life will be reduced by half.

Air compressors are constantly subjected to adverse conditions such as dust, moisture, heat, high speeds, long operating intervals and high pressures. Each of these factors affects the ability of the compressor to provide maximum output when needed. Bearing, ring, vane, gear, rotor and cylinder wear are very common. Carbon, gum and varnish buildup lead to reduced efficiency and failure. Oil deterioration results not only in excessive wear, but higher energy costs and more downtime.
