The GEOVENT dust filter is used as a supplement for existing filter plants. The filter is designed for being built into the ducting system, where separate filtration is required to protect the extraction fan - for example at grinding machines, belt sanders, etc. As standard, the filter material is EU3 with a separation efficiency of 85%, but it is also available in EU5.

The filter is fitted into a retractable cassette with a built-in brush system for cleaning. The dust can be emptied into a bin or a bucket via a sliding damper.
