This cools the airend and reduces thetemperature of the compressed fluid must withstand heat and pressure, and absorb the contaminations en-countered in every informationKAESER cooling fluid intended for fluid injected airends must be stored according to environ-mental regulations and protected such that contamination and hazards are is imperative that national legislation covering transport, storage,use (especially regulations for oil changes)
