Application
The product is an isolated positive pressure respiratory system protection device made of compressed medical oxygen. It is mainly used by mine rescue personnel when they are engaged in rescue and relief work. The shell adopts PA material, which is heat resistant and wear resistant, durable. The mask is made of anti-fog spherical silica gel, with wide vision and comfortable to wear. The cylinder is made of carbon fiber composite material with high strength and good quality, and has the characteristics of pressure relief before crushing. Adopts imported integrated type pressure reducing valve, with stable performance, safe and reliable. The respiration loop adopts blue ice physical cooling, with low breathing temperature and good comfort.
