Application

The Primus-FK backwashable filter combination integrates a backwashable fine filter and pressure reducer into a single unit. This ensures a continuous supply of filtered water. The fine filter prevents the ingress of foreign particles such as rust particles, hemp remnants, and sand grains. The pressure reducer prevents damage from excessive pressure and reduces water consumption. Primus-FK filter combinations are particularly suitable for retrofitting or modernizing existing domestic water systems where an existing filter needs to be replaced. For new installations, the DA74C swivel connector must be used (see accessories).
