Application
The Primus-FK backwashable filter combination has a backwashable fine filter and pressure reducer integrated into one device. They ensure a continuous water supply with filtered water. The fine filter prevents foreign particles such as rust particles, hemp residue and grains of sand from being washed in. The pressure reducer prevents pressure damage and reduces water consumption. Primus-FK filter combinations are especially suitable for retrofitting or modernizing existing domestic water systems in which an existing filter needs to be replaced. The rotating connection piece DA74C must be used for new installations (see accessories).
