The cost-saving, environmentally friendly SMC Series FN1 filter for machine tool and general machinery industries generates no industrial waste, as it has no replaceable filter elements, and requires little maintenance. The filter element is constructed of grooved filter plates and wave washers compressed by a compact cylinder on top of the filter. When the element is compressed, foreign matter in the fluid is trapped in between the plates and washers. Decompress- ing the element allows the foreign matter to be back-flushed and washed away for collection. Filtration and back-flushing can be carried out manually or automatically. The filter operates in tandem with the FNR reservoir, which stores the fluid required for back-flushing, and the FND dust recovery filter for collecting the debris. All three units are constructed primarily of stainless steel SUS304 and form an integrated circuit for industrial waste removal. The filter is compatible with water, and water-soluble and oil-based coolants.
