High-efficiency Filter Scanning Test Bench
Category：Filter Cartridge Filtration Tester
Introduction
The high-efficiency filter scanning test bench (referred to as the test bench) is designed and manufactured in accordance with the principles and requirements of the European standard EN1822-4 and in reference to relevant standards. Under the determined air volume conditions, test the efficiency and resistance of the filter and use the automatic scanning method to detect leaks in the filter. The location of the leak point can also be repeatedly detected manually. The foundation and core of the test bench is the particle counter. The aerosol medium used in the test bench is liquid aerosol (DEHS), with a particle size of ≥0.3μm(0.1μm can be selected according to customer requirements).
