Our stainless and special steels filters are ideally suited for de-dusting hot exhaust gases. A typical application is product cleaning after wood gasification. Depending on the quality of the raw materials used, the product gases contain condensate (tar), ash, and dust. If polymeric filter media are used, the gases must be cooled before filtration. Consequently abrasive or adhering particles enter the heat exchanger, which may cause operational problems. 

High temperature resistant filters enable hot gases to be de-dusted and consequently protect all following components.
