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.

AFP-AZ Comfort


AFP-AZ Comfort gas adsorption filters are an excellent, inexpensive method for removing odours and improving indoor air quality in air-conditioned buildings – an important contribution to the cure of “sick building syndrome” (SBS). AFP-AZ Comfort are designed to remove contaminations which can cause unpleasant physical reactions of the occupants, e.g. headaches and nausea.

Gaseous, odourous compounds can be fed into room air from a car or airplane exhaust, or alternatively they may occur due to material emissions and processes indoors. AFP-AZ Comfort removes such compounds and purifies the air by making use of a high-quality activated carbon composite material. The composite material is based on fine grain granular adsorbents embedded into a synthetic textile matrix.

Fitting into standard fine dust filter frames, AFP-AZ Comfort can be used to supplement current mechanical particulate filters.
