Bag Air Filters

MANN+HUMMEL's range of bag air filters (or pocket filters as they are known in some regions) offers the ideal solution for a number of applications. Innovative frame and pocket designs mean our bag filters offer industry-leading performance and quality assurance you can rely upon. What's more, through the careful selection of different media types (from inherently antimicrobial to the latest nanofibre technology) there is a bag filter below to meet your individual clean air needs.

Revo DuoSorb


Removing particles and odours from the air is typically a two-stage process, requiring separate filter elements for each task. Revo DuoSorb changes this by delivering effective particle and odour separation in one filter element – removing the need for an additional stage.

This is thanks to Revo DuoSorb’s synthetic filter media, which provides particle filtration to class M6 (EN779), whilst efficiently removing all odours and other dangerous gases.

A strong gas adsorption performance makes Revo DuoSorb ideally suited to applications experiencing problems with emissions from traffic, combustion or other odorous processes.

Ventilation systems are usually designed with a limited number of particle filters in mind. With Revo DuoSorb, you can introduce high performance gas filtration without having to rebuild the facility.

* Notes

Revo DuoSorb is manufactured in a number of sizes and specifications. The data above refers to a filter 592 x 592 x 635 mm, with 8 bags. If the maximum relative humidity is exceeded gas adsorption performance may be impaired. Gas adsorption will return to normal when the humidity drops below the maximum value.
