1. Application: It is used to determine the leakage rate of particles in masks, face masks, respirators and gas masks.
Second, meet the standards
GB 2626-2019 Respiratory protective equipment Self-priming filter anti-particulate respirator 6.4 Leakage
GB 2890-2009 Respiratory protection Self-priming filter gas mask and other standards.
3. Product features:
1. The size of the detection chamber is 2000mm long, 2000mm wide, 2500mm high, and the volume is 10m³. The silo body is made of stainless steel frame and tempered glass.
2. The stable flow net at the top of the detection chamber makes the gas form an irregular swirling flow, accelerate the gas mixing, so that no dead angle is left in the cabin, and the pollutant uniformity required by the experiment is reached after several cycles.
3. The overall structure of the inspection chamber is mainly composed of cabin, air purification system, exhaust duct and air sampling system.
4. Sampling (inlet) sample hole: 304 stainless steel material, a total of four, ball valve control, with hose.
5. Guardrail: Install guardrail on the sampling hole surface.
6. Lighting: 2 LED fluorescent tubes (lighting lamps and fans are installed on the top of the test cabin, fixed inside and outside with Teflon material, and sealed with non-releasing imported glass glue).
7. Air exhaust system (external purification system): ensure that the air discharged from the sewage outlet can meet the emission standards.
8. A set of particle concentration detection device.
