Positive pressure air respirator is a personal protective equipment used to provide clean air in hazardous environments. It is widely used in fields such as fire protection, chemical engineering, mining, emergency rescue, etc., ensuring safe breathing for users in toxic, oxygen deficient, or heavily polluted environments.
working principle
Positive pressure air breathing apparatus reduces the pressure of high-pressure gas in the gas cylinder through a pressure reducing valve, and then delivers the air to the face mask through a gas supply valve. The inside of the mask always maintains positive pressure to prevent the entry of toxic gases or particles from the outside, ensuring that the user can breathe clean air.
advantage
High safety: The mask always maintains positive pressure to prevent pollutants from entering.
Strong adaptability: suitable for various hazardous environments, such as fires, chemical leaks, etc.
Easy to use: Automatic adjustment of gas supply, no manual operation required.
Precautions for use
Regular inspection: Ensure that the gas cylinder pressure is sufficient and all components are intact and undamaged.
Proper wearing: Ensure that the mask is well sealed to avoid air leakage.
Training usage: Users need to undergo professional training, familiarize themselves with equipment operation and emergency response.
Timely replacement of gas cylinder: When the pressure gauge shows insufficient pressure in the gas cylinder, it should be immediately evacuated and replaced.
