Filter efficiency testing device of mask
The particulate filter performance tester is applicable to test the filter efficiency of the 0-99.999% level mask, and test the mask according to the standard. The design of the whole tester is compact and portable, and the test air volume corresponds to the required flow on the fixture during the operation test. The aerosol produced by the aerosol generator is adjusted, and then neutralized by static electricity, and then mixed with the filtered test air evenly, and then enters the test area through the filter material. In order to measure the efficiency, a separate stream of air is drawn upstream and downstream of the mask. Use a photometer to measure the concentration of particles in the sampling air stream, and then obtain the measured efficiency through the ratio of upstream and downstream. In addition, the resistance of filter material during the test can be measured and the flow can be adjusted and controlled.
