Evenly distribute the dust into the suction pipe with a diameter of 100mm through the dust distributor, and then suck the dispersed aerosol into the test hood by the standard suction pipe. A standard-diameter exhaust duct and a related dust particle sampling device are installed on the top of the test hood. The filtration efficiency is analyzed and calculated through the upstream and downstream sampling devices and control systems. The main components of the dust filtration efficiency testing equipment are: central control system, servo-controlled distribution conveyor track, distribution suction system, air inlet channel sampling tube, test hood, exhaust channel sampling tube, and laser particle size analyzer.
