Mask particle protection device

Mask particle protection device

Product Introduction:

The particle protection effect tester for masks is equipped with a national standard head mold placed in a 500L self-cleaning detection chamber. The mask to be tested is worn on the head mold, and the median diameter of the mass produced is 0.6 μ m. Salt aerosol with a concentration of 25mg/m3 and a median mass diameter of 0.3 μ m. An oily aerosol with a concentration of 25mg/m3 is inputted into the self purification detection cabin. The head model is simulated with a sinusoidal curve to simulate respiration. The concentration of salt and oil aerosols before and after the mask is sampled and detected using upstream and downstream photometers, and the filtration efficiency of mask particles is calculated. The mask to be tested can be worn on the national standard head mold to automatically detect respiratory resistance. Applicable to medical device inspection institutes, disease prevention and control centers, hospitals, high-efficiency filter manufacturers, mask R&D and production manufacturers, etc., to test the filtration efficiency of particulate matter such as masks and filter media.
