Filtration medium B/220, KS B/290 Technical information (PDF 54,5 kB)

The filter media consist of at random arranged twisted non-woven synthetic fibres of various thickness, fortified with a plastic binder (or thermally) into a solid and stable filter lap. Due to the progressive structure of fibres, the materials have extremely low pressure losses and a high dust accumulation capacity.

Field of application: They are used as pre-filters or the 1st stage of filtration in air conditioning and ventilation units.
Waste disposal: Landfilling or incineration in authorised incineration plants.
