While also reducing or eliminating the servicing procedures necessary with conventional filters to clean or replace the filter cartridge.
In SeIf—CIeaning filters, the trapped impurities are removed by means of a backwashing action provided by an impeller with holes of calibrated size fitted inside the filter cartridge itself, which sprays a jet of pressurised water across the entire cartridge surface and drives the trapped deposits to the drain outlet.
In Easy filters, the filter maintenance is reduced to simply draining the water off by hand using a foot valve. This procedure takes just a few seconds and removes the coarse dirt trapped in the filter cartridge. Culligan Self—CIeaning and Easy filters use high quality non—toxic materials and are available in automatic, semiautomatic and manual versions.
