Atlas Copco Oil-Injected Rotary Screw Compressor GA22VSD+

Atlas Copco's Roto-Foodgrade Fluid is a unique high quality synthetic lubricant, specially created for oil- injected screw compressors that provide air for the food industry.

This lubricant keeps the compressor in excellent condition. Roto-Foodgrade Fluid can be used for compressors operating at ambient temperatures between 0 ̊C (32 ̊F) and 40 ̊C (104 ̊F)

If the compressor is regularly operating in ambient temperatures above 35 °C (95 °F), oil lifetime is reduced
