Cabin Air Filter Test System For Gas Adsorption

Cabin Air Filter Test System For Gas Adsorption

Skype / Email

  
Since 1995 our company has been developing test stands for measuring the adsorption capacity or desorption behaviour of adsorptive filters. The design of the test stand, the test procedure and data aquisition have been based on the DIN 71460-2 standard and ISO 11155-2. 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 metering 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 by-passing the test channel facilitates maintaining a very stable gas dosing even when the filter must be inserted or removed. This technique of a continuous exhaust also meets stringent safety requirements.
