AIR COMPRESSOR LUBRICANT

To help lubricate, cool and seal the moving parts within the air end, special oil or ‘coolant’ is injected into the rotating air end. The coolant also has a tough life. Its role is not just to lubricate but also has to withstand the high temperatures created by the compression process and carry this heat away from the air end. It also picks up water, which comes out of the compressed air, and carries this away too. The coolant is then spun to separate it from the compressed air, filtered to remove water and contaminants and the cooled before being injected back into the air end. No wonder the coolant needs to be a specialist screw compressor, high specification grade of oil.

Lubricated screw compressors come in a range of sizes ranging from 5 to 250kW motor power.
