1. Positive pressure air respirator is a self-contained open respirator. It is widely used in firefighting, chemical industry, shipbuilding, petroleum, metallurgy, gas, oil storage, laboratory, mining and other industries, for firefighters or emergency rescue personnel to safely and effectively carry out firefighting, rescue and rescue work in environments such as thick smoke, toxic gas, hypoxia or toxic and harmful substances.

2. During use, the pressure inside the mask is always higher than the ambient atmospheric pressure, so its use is not limited by the concentration of harmful gases in the environment, nor by the concentration of oxygen in the environment. It is a very adaptable respiratory protection equipment.

3. The equipped mask has a wide and bright field of view, good air tightness, and can be quickly connected or disassembled with the supply valve. The radial and axial dimensions of the configured supply valve are small, so that the field of view under the mask can be expanded. The supply valve adopts a wear-free mechanism, which prolongs the service life and reduces the amount of maintenance.

4. It is equipped with a residual gas alarm, which can send a sound signal to the wearer under the specified gas cylinder pressure. After the residual gas alarm sounds, the product can still be used for 5-8 minutes, which is convenient for users to evacuate the scene in time.

5. The residual gas alarm is on the chest of the wearer. Even in a noisy scene or where several staff members work together, the alarm whistle can be clearly heard to distinguish whose instrument has sounded the alarm.

6. The mask and supply valve can be quickly combined and disassembled, so the wearer's dressing and use and disassembly and maintenance are simple and convenient.

7. The rated working pressure of the respirator is 30Mpa. The gas cylinder has a carbon fiber composite gas cylinder with a volume of 3.0L, 6.8L, and 9.0L, and the webbing is made of flame retardant material.

8. The respirator is suitable for environments with hypoxia and high concentrations of toxic and harmful substances. Users must read the instructions carefully before use and can only be put into use after systematic training! Failure to properly inspect and maintain the respirator may cause injury or death to personnel.
