Using regenerable filter cartridges with filter media of filter class H13, the residual dust values of the former HEPA filtration can be achieved with only one filter stage. Expensive process interruptions during filter replacement of the second filter stage are thus a thing of the past. In particularly sensitive areas, such as the chemicals or pharmaceutical industries, the two-way-filter can be used as plug-in or top filter. Depending on the application, it serves as the first or second filter stage.

The Two-way-filter can be used for aspiration, for venting pneumatic conveyors, as a safety filter and for many other applications. The filter apparatus is integrated autonomously into the process or inserted in the bypass as a police filter on the exhaust side for process control and thus, contributes to a controlled ventilation of the process. It can also be used for the controlled course of an explosion in a pressure-resistant housing.
During filtration, the dust-laden raw gas flows from the outside to the inside through the filter element. The dust forms a growing dust cake on the outside of the filter element. The filter element is regenerated from time to time by means of compressed air pulses. Due to the mounting by means of a clamping connection, the filter element can be changed without tools. Due to the metallic design of the filter element, additional cleaning can be carried out at higher temperatures as well as using the ultrasonic cleaning method.
