該產品是在刮板排屑器的基礎上的改進型產品，適合于切屑量較大的機床。具有高效，壽命長和低運行成本等優點。可以通過更換不同的過濾網來滿足不同客戶、不同的過濾精度的要求。
臟液進入過濾箱以后，較大的顆粒直接沉淀在過濾箱的底部，干凈的液體進入凈液箱，而附著在過濾網的外部小顆粒雜質被沖洗水泵沖落在過濾箱的底部，由刮板刮進污物箱。由于過濾網自動清洗，可持續工作，所以這是一種低消耗、高效率的高檔產品。
The equipment is the advanced product of the chip conveyor （scraped type）. The equipment is fit for the filtration of the heavily contaminated coolant, with the advantage of high efficiency, long life service and low operating cost. The equipment can meet the different requirement of precision from the customers by the different web.
After the dirty coolant flow into the dredged tank, the large solid particles fall onto the bottom of the tank, the clean coolant flow into the clean tank, the filtered coolant is pumped to wash the particles attached to the outer side of web, the small particles fall onto the bottom. The dirt is scrapped into the dirt box. The filter is a low consumption, high efficiency and high-grade product, because the web is auto-washed, operate continuously and not to clear by man.
