Over view
Positive pressure air breathing apparatuses is a device for breathing and protection of human body by using compressed air as a gas source. It is mainly used in fire fighting, chemical, petroleum, metallurgy, shipbuilding, mining, laboratories, oil depots, warehouse and other departments for rescue and disaster relief. For the firefighters and emergency rescue personnel to carry out firefighting, rescue, disaster relief and rescue work safely and effectively in smoke, toxic gass, dust or oxygen-deficient environments.
