Innovative protection filter to remove suspended particles, sand and metal particles. Manufactured with Delrin body, 360° rotating brass Inlet-Outlet connection plate, transparent SAN bowl, plastic drain valve. The filter is supplied complete with nylon filtering element. The water enters the filter and flows down to the cartridge from inside to outside.
A simple turning counter-clockwise of the knob activates high speed-wash with water, by the “Venturi” functioning principle of the interior plastic slot cylinder. Dirty water goes out by the drain valve. To finish cartridge cleaning operation turn clockwise the knob. No interruption of filtered water supply during cartridge-washing operation.
