4 hours HYZ4 Isolated Positive Pressure Oxygen Breathing Apparatus
HYZ4 Isolated Positive Pressure Oxygen Breathing Apparatus
Application
It is mainly applicable to coal mine, fire protection, chemical industry, and tunnel, scientific research fields where there is noxious gas or oxygen insufficient emergency.
Main Characteristics
1. Antifog spherical silica gel mask, wide field of vision, more comfortable on the face when contacting with mask.
2. It adopts carbon fiber composite cylinder, has the characteristic of high strength, good quality, light weight, and pressure relief before breaking up.
3. Adopting imported French integrated pressure reducing valve, it is much more safe and reliable.
4. It adopts blue ice to give physically cooling to breathing circuit, to guarantee the comfort of breathing temperature.
