Shops, construction sites, cold storages and manufacturing facilities all rely on compressed gas systems, with air compressors playing a critical role. Proper lubrication is key to maintaining equipment performance, reducing downtime and energy consumption. Compressed air systems are major power consumers, making energy-saving lubrication practices a valuable improvement opportunity. 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.
