Domestic water filter type

The KÖPP MSM normal water filter is fitted as standard with a depth filter cartridge made from VYON® low pressure polyethylene, Type A 70/223 mm, filtration rating 80 my. This filter cartridge is also available with a filtration rating of 25 my.

The domestic water filter is also available with a Type G  70/223 mm, spun nylon, filter cartridge with filtration ratings of 80 my, 250-300 my and 700 my.

The standard version of the MSM water filter has a transparent filter bowl. A version with a brass bowl and a 1/2” sealing plug is also available.

The MSM normal water filter can be fitted with two pressure gauges with a 0-10 bar scale range. The gauges measure differential pressure and thus provide an indication of how dirty the filter cartridge actually is.

Maintenance

The filters should be serviced at regular intervals in order to ensure trouble-free operation. The intervals at which you should actually service a filter unit depends on operating conditions and how dirty the filter is. For reasons of hygiene the filter cartridge should be changed at least once every six months or whenever the pressure drop is more than 0.5 bar.
