A low maintenance filter, series FN1 eliminates the need for element replacement. SMC's unique element construction is composed of a series of grooved filter plates and wave washers placed one above the other. When compressed, the gaps between the filter plates and wave washers filter foreign matter. When decompressed, the element widens the gap between the filter plates and wave washers, allowing dust and foreign particles caught between the plates to be washed away. The gaps between the filter plates are equally maintained by the wave washers to allow stable back-flush operation.
Quick change filter series FQ1 requires no tools for replacement of the element. Element replacement, including removing liquid, can be accomplished in less than 2 minutes. Element sizes include 125mm, 250mm and 500mm. Materials include PP, cotton, SUS304 (epoxy resin) and SUS316 (nickel solder). Other elements are available as made-to-order.
