RF600-S air pressure oil filter is mainly composed of gross oil barrel, air compressor, tank card and other components, which is suitable for filtering all kinds of crude oil extracted by the screw oil press machine, but it can also filter other oil containing solid impurities. The air compressor presses the gas into the gas storage tank through the gross oil bucket, and the gross oil permeable filter cloth flows out. The solid particles in the gross oil encounter the filter cloth, which is blocked outside to form the filter slag, so as to get a clear filter oil.
