The Filter Test System for gas adsorption/desorption of air filters for passenger compartments (DIN 71460-2, ISO 11155-2). The Adsorption Test Stand for air filters for passenger compartments is used for quantification of adsorption capacity or desorption behaviour of filters.

The design of the Adsorption Test Stand, the test procedure and data acquisition have been based on the draft standard DIN 71460-2 and ISO 11155-2 standard for measuring the dynamic gas adsorption.

The test section and associated ductwork are fabricated from stainless steel. Different sizes of filter media samples and elements can be tested and are mounted in a special adapter. A window in front of the test section allows visual observation of the sample during the test. A pair of mass flow controllers is used for dosing gaseous components from gas cylinders and a new, sophisticated, dosing unit for liquid gas components has been developed specifically for this application. This is based on evaporation of a droplet spray atomized by means of a two-stream nozzle fed from a µl-dosing pump. The gas concentration can be measured downstream of the filter. An exhaust system bypassing the test channel facilitates maintaining a very stable gas dosing.
