Adsorption filters are made in a casing made of a galvanized metal frame and material pleated under the influence of 180º C. Thanks to this design, the filter is characterized by high mechanical strength. The thermosetting pleat technology ensures also long service life (the filter is resistant to tearing). Filtration medium, made of activated carbon, removes gaseous odor compounds from the air unpleasant smells, odors. Thanks to the use of carbon (adsorptive) filters, we can eliminate unpleasant odors coming from the environment and introduced into buildings, as well as those that come from processes occurring inside buildings e.g. from smoking rooms, restaurants, dining rooms.
