EN149 2019 N95 Respirator Leakage And Walk Testing Equipment

 

Breathing mask leak test equipment is used to detect the filtering efficiency and protective effect of breathing masks and protective masks.

 

 

Product Description:
1.The environmental test chamber for inspection consists of a size of 2000W×2000D×2500H m and a volume of 10m 3. The cabin is made of stainless steel frame and tempered glass.
2.The stable flow net on the top of the test chamber makes the gas form an irregular swirling flow, accelerates the gas mixing, and keeps no dead angle in the chamber, and reaches the pollutant uniformity required by the experiment after several cycles.
3 The overall structure of the environmental test cabin is mainly composed of the cabin body, the air purification system, the exhaust air duct, and the air sampling system
