Gas Adsorption Filters

Available in a variety of formats, MANN+HUMMEL's gas adsorption filters utilise a variety of materials including the latest impregnated and activated carbons. Designed for the elimination of odours and toxic or harmful gases, these carbon filters provide the ideal solution for preserving comfort air, and protecting people and processes in cleanroom environments.

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.
