Pleated filter element: Commonly made of high molecular materials such as PP andPTFE,it increases the filtration area through a pleated design.Polyester fiber has ex-cellent mechanical properties and high-temperature resistance. The filter layer,cen-tral rod and end covers at both ends are integrally injected with rubber.
It features high filtration accuracy, capable of removing tiny particles, microorgan-sms,etc.,and has excellent air permeability and waterproof performance. Folded PPs gradually replacing melt-blown PP cotton. Its features include high flow rate, lowpressure loss, strong dirt-holding capacity, and strong controllability in foldingheight, number of folds, precision and thickness.
