Product Details

The new high efficiency filter material filtration performance tester uses the current international mainstream particle counting method, the high efficient large flow laser particle counter to test the basic filtration performance parameters of filter material, such as filtration efficiency, particulate transmittance, pressure drop curve, residual pressure drop, filtration/cleaning cycle, etc. The alternative patented horizontal and vertical structure achieves a comprehensive test for filtration material, compatible with more testing requirements. Combined with the life span testing module, the testing system can make cyclic test for filtration material so as to obtain the dynamic filtration performance of the filtration material as well as the information on efficient filtering life span.

The unique alternative vertical dirty gas pipe can simulate the actual use process of filtration material. It is applicable to test the basic static filtration efficiency and to provide actual simulation test for research and development, achieving the verification of versatile function performance of filtration material. The bottom is equipped with a dust collector, to avoid the dust re-dispersion to the air upstream of the tested filtration material, which lead s to the uncertainty of the dust concentration and invalidity of the measurement (especially important parameter: residual pressure drop value). The design of the instrument achieves long term operation with zero error, and there is no need of frequent full suspension of the measurement for cleaning the dust deposition.
