The test rig APM 2003 was constructed and supplied by Palas® especially for investigation of particle penetration through fabrics and other permeable materials.
With this test rig concept, the flow over the material under testing is designed in a realistic manner and is made up – as required either fully or optionally (through replacement of the inflow module) – of different angles.
The particularly versatile test rig is equipped with a removable sample holder, which can be modified for various applications. Another advantage is the option of operating the APM 2005 with various aerosol generators. The test material can be tested as required with droplets, salts or dusts.
As a result, with this test setup it is also possible to test filter media or entire filters instead of the protective clothing fabric.
