Masks Particle Filtration Efficiency Tester
Face masks particle filtration efficiency (BFE) tester is device to determine the particle filter penetration and filtration efficiency for respiratory protective devices and face masks. The tester with particle generator can provide sodium chloride particles and paraffin oil particles. It can measure the particle penetration, filtering efficiency and the breathing resistance delta P. It is widely used in quality control, research and development, certification, manufacturing or testing industry, etc.
