YYE032 Facial Particle Filter Tester (PFE)
Product Introduction Description
Particulate Filtration Efficiency Tester is suitable for fast, accurate and stable detection of particulate filtering efficiency of various medical and daily protective masks, respirators, etc.
With clean compressed air, the prepared NaCl solution or a similar solution such as DEHS/PAO are sprayed from the aerosol generator. After passing through a classifier (inertia principle), unneeded large particles are collected into the collection bottle, and particles meeting the requirements enter into the test system from the nozzle of aerosol generator
