Drinking water filter with replaceable filter cartridge
Although drinking water is clear when it leaves the water plant, it can absorb various particles such as rust particles and grains of sand on its one-kilometre journey to the consumer. For the protection of drinking water installations, there are therefore technical regulations concerning the installation of a mechanical filter..
DIN 1988-200, 12.4 Mechanical filters
A mechanical filter must be installed directly behind the water meter system.
DIN 806-2 B.4.2 Scope of application
The washing of small solid particles such as rust particles or grains of sand in the drinking water system must be prevented. These particles can impair the proper functioning of, for example, water heaters, shower heads, etc. or cause corrosion damage in the installation due to pitting.
DIN EN 806-5 Maintenance intervals for mechanical filters
For hygienic reasons, a filter cartridge replacement interval of 6 months must be observed for filters that cannot be backwashed and a backwash interval of 6 months must also be observed for backwashed filters. A backwash interval of 2 months is recommended.

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.

High quality manual backwash filters
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.
