The dirty liquid, channelled through a distributor that prevents turbolences, flows through the nonwoven fabric and after being cleaned, flows into the under tank and put it back into circulation by a delivery pump. The deepness of the filtering bed allows to reach a high hydrostatic delivery head and consequently a high flow rate. A tubular gasket, resistant to all common coolants available in the market, separates the collecting dirty chamber from the clean one. The dirty particles accumulate onto the fabric building up an additional layer of high quality that improves its filtration degree. The solid particles that built up clog the filter causing the raising of the liquid. When the set maximum level is reached, the floating switch starts off the advancing belt. The dirty fabric is conveyed into a dust bin whereas the clean fabric is ready again for filtration. Thanks to the short fabric advancing, only a small part of it is renewed so as to take advantage from the optimization of the fabric consumption and the better filtration result as the liquid goes through the layer created. The fabric advancing stages do not interrupt the filtration process. An end-of-roll mirco switch signals the end of the fabric roll.
