Compact design meets system safety with simplex strainers

Simplex strainers are especially advantageous in situations where systems or filters can be deactivated using additional shut-off mechanisms. Their primary purpose is safeguarding system components against contamination.

BOLLFILTER simplex filters not only fulfill rigorous technical filtration and reliability criteria but also align with the performance standards of our switch-over duplex filters and automatic filters. Depending on your application, a diverse range of options for housing materials and filter element designs is at your disposal. Our simplex filters are characterized by their compact design, minimal component count, and user-friendly cleaning process, catering to both liquid and gas filtration requirements.

Simple steps to clean your filter

Cleaning these simplex filters is a straightforward procedure. To initiate the cleaning process, depressurize the filter chamber and remove the housing cover. The filter element can then be easily removed, flushed with a cleaning fluid, and thoroughly cleared of contaminants using compressed air.
