Positive pressure oxygen breathing apparatus is a respiratory protection device worn by firefighters and emergency rescue personnel when they are used for disaster relief or disaster relief in toxic, anoxic, smog and airborne hazardous pollutants.

Closed-circuit positive pressure oxygen breathing apparatus is mainly used for fire-fighting fighters in special occasions such as fire fighting or rescue, to prevent inhalation of harmful gases, smoke, harmful pollutants suspended in the air or used in anoxic environment. Oxygen breathing apparatus cylinders are full of gas, and the time required to fill the CO 2 absorbent is 240 minutes, meeting the GA632-2006 standard.

●Technical specifications Quantitative oxygen supply: 1.55 liters / minute Automatic supply valve air supply: 105 liters / minute Manual supply valve air supply 87 liters / minute, airbag volume: greater than 5 liters.

● Mask: Suitable for Asian face type, with anti-shock, anti-fog and other functions. Wear a mask to ensure a good call.

●The volume of the cylinder water is 2.4L and the working pressure is 200MPa.

●Alarm device Automatic high-pressure air tightness test, quantitative oxygen supply test, and need to have cylinder residual pressure alarm and hypoxia alarm. In low light environments, a background light background is required. A high-pressure sensor is required on the pressure reducing valve to ensure that an alarm signal can still be issued in the event of a malfunction of the pneumatic system.

● Each set of oxygen contains four kilograms of special CO 2 adsorbent and cooling agent.
