该产品是在刮板排屑器的基础上的改进型产品，适合于切屑量较大的机床。具有高效，寿命长和低运行成本等优点。可以通过更换不同的过滤网来满足不同客户、不同的过滤精度的要求。
脏液进入过滤箱以后，较大的颗粒直接沉淀在过滤箱的底部，干净的液体进入净液箱，而附着在过滤网的外部小颗粒杂质被冲洗水泵冲落在过滤箱的底部，由刮板刮进污物箱。由于过滤网自动清洗，可持续工作，所以这是一种低消耗、高效率的高档产品。
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.
