GEA Deichmann Bag Jet filters

In close collaboration with leading manufacturers of filter media, Air Treatment applies the filter material that is optimal for the respective applications. As a result, use is primarily of needle felt made of synthetic fibers such as polyester, polypropylene, polyacrylonitrile, and poly­phenylen­sulfide. At higher gas temperatures, the filter hoses are made of Teflon© oraramids. In temperature ranges above 260°C, the use of woven fabric hoses made of stainless steel is effective. Gaseous pollutants are absorbed from the exhaust gas with the aid of additives, and are separated by GEA Deichmann hose jet filters.

Filter hoses with diameters of 120 or 150 mm are installed in chambers with modular configuration. The dust that has been removed from the filters by pulse-jet cleaning is collected in troughs or funnels, where it is removed. Large service hatches with weight relief at the filter cover simplify the access to the clean-air zone. The filter hoses are secured and sealed in the hose mounts by snap rings. The pulse-jet nozzles, which are mounted above the filter hoses, are easily installed with plug-in connectors with O-ring seals.
