Spin-on filter
minimaster spin-on filter
perfect entry-level
First-class materials and mature technology for a long service life and therefore: the obvious favourite for a cost-effective entry into filter technology. Our high-quality spin-on filter protects fittings and drinking water installations against alluvial dirt particles. As the filter head can be used as a universal connection piece, it is always open to upgrade to a Permaster black backwash filter.
- Protects fittings and valves from dirt particles
- The degree of contamination is visible at all times thanks to the transparent filter cup
- For hygienic reasons, the filter cartridge should be replaced every 6 months
- Can be easily upgraded at any time to the more comfortable Permaster black backwash filter
- Available in DN 25 to DN 32

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.
