Backwash filter with pressure reducer

permaster black

Reduce water consumption. And enjoy full comfort.

Filter-pressure reducer combinations of the permaster black series are characterised by all the advantages of the permaster black backwash filters. In addition, the inlet pressure can be reduced and the integrated pressure reducer compensates for pressure fluctuations from the supply network. This effectively protects valves and equipment from damage. Reducing the water pressure to the desired level reduces water consumption without loss of comfort.

  • Protects the drinking water installation from alluvial dirt particles
  • Particularly durable and stable thanks to high-quality materials
  • Light protection against algae formation through tinted filter cup
  • Double cleaning effect for filter sieve and filter cup due to specially developed strip brushes
  • Integrated pressure reducer protects valves and equipment from pressure surges
  • Reduction of water pressure reduces water consumption without loss of comfort
  • Available in connection sizes from DN 25 to DN 50

The permaster black backwash filter effectively prevents the ingress of dirt and – thanks to its optimized design – is now even more comfortable. The new black-tinted filter cup not only impresses with its particularly elegant appearance, but also offers additional protection against light and algae formation. The transparent cup also allows you to see at any time when the filter needs to be backwashed. According to DIN EN 806-5, the filter must be backwashed every six months at the latest. This can be done easily and practically in the blink of an eye. By turning the drain funnel, the patented belt brushes clean the stainless steel filter and the filter cup without interrupting the water supply. There is no need to replace the filter element.
