Simplex Filter

Advantages of the Simplex Filter

Simplex filters are the basic model of filtration technology. They have a compact design and are extremely easy to clean. The simplex strainers are preferably used where systems or the filter can be switched off with additional shut-off devices. They serve to protect the system parts from soiling and siltation.

The simplex filters meet technical filter and reliability requirements to the same level as switch-over duplex filters or automatic filters from BOLL & KIRCH. Depending on the application various options for housing materials and filter element designs are available and can be used. The simplex filters from BOLL & KIRCH provide a compact design and minimum number of parts, as well as the simple cleaning. Both liquids and gases can be filtered.

Cleaning of Simplex Filters

Cleaning of the simplex filters is very simple. To do so, the filter chamber is depressurized, the housing cover is removed, the extracted filter element can than flushed in cleaning fluid and blown out with compressed air.
