OIL KILLER Oil-free Purification System

An oil-free purification system for compressed air includes: an oil-based air compressor which provides compressed air; The low-temperature filtration and drying system comprises a nano glass fiber filter and a first heat exchanger, wherein the first heat exchanger reduces the temperature of compressed air, increases the viscosity of oil by using low-temperature deceleration, enlarges water molecules, and is easy for water droplets to collide with oil mist to be coated, so that the condensation speed is accelerated to reach oil droplets, which are filtered and assembled by nano glass fibers and recovered into large oil droplets to be actively taken out by an electronic automatic blowdown device, so as to output clean oil-free air.
