The air cleaner, uses in the motor car engine air admission filtration, is mainly composed of the outer covering and the filter element. By filter element with under shell looping cavity room, this cavity room side has a tangential air inlet. The filter element swollens the pine by the thin tinsel woven mesh to circle the system to become, places in filter element fixed. Underneath the filter element is equipped with an oil sump, the filter selects the method which the centrifugal separation and the lubricant film adsorption unify to carry on filters thickly, fine filters using the oil bath type wire netting filter element, therefore has the filtration efficiency to be high, the intake resistance is small, not loses the oil, Chu Huiliang is big and life long merit. |
