It’s great significant for Dynamic Filter Tester and filter media test system bench to optimize and develop filter materials, ensure quality assurance of the production process. Dust capacity and filtration efficiency are the most interesting properties of filter material properties, depending on the pressure difference between the upstream and downstream of the filter and the test particle size.
In order to test these properties, the Filter test bench bench tests the filter materials according to international standards. The entire test bench is compact and lightweight, and only requires additional single-phase power and compressed air during the test. It is suitable for the laboratory.
Air filtration material test bench Standards
