The Fk series quick coupling filtering cartridge containers are made from transparent PET (Polyethylene terephthalate) and a brass ring nut that comes with an interposed seal. The cartridge can be selected in various materials such as pleated paper, pleated polypropylene mesh and AISI 304 stainless steel mesh. It has a working pressure that ranges from 0.5 to 9,000 mbar abs.
The temperature of sucked fluid ranges from -10 to 45 °C. The filtering cartridges, once installed on the container, are able to retain the impurities and dust contained in the sucked fluid, interfering with the vacuum pump or generator capacity in a negligible manner.
