Prepared by the cotton fiber or polypropylene fiber, the system has avoided filtration effect. The initial filtering accuracy is lower. The pressure is gradual lyincreased, and he filter accuracies gradually improved.

    So this filter is particularly suitable for occasions of loop filter. The disadvantage is that the backwashing could not recycled, and in the use process is easy to dropafibermixed with oil, and the use of WLX type composite stainless steel filter combination, the advantage of filtering precision is high, the price is cheap.
