Positive pressure oxygen respirator is a respiratory protective apparatus used by firefighters and emergency ambulance personnel to carry out emergency relief or engage in disaster treatment in harsh environments such as toxic, hypoxia, smog and harmful pollutants suspended in the air.

Closed-circuit positive pressure oxygen respirator is mainly used in special occasions such as fire fighting or emergency rescue to prevent the inhalation of harmful gas, smoke, harmful pollutants suspended in the air or used in hypoxic environment.Oxygen respirator gas cylinders full of gas, and filled with CO2 absorbent time to reach more than 240 minutes, to meet the ga632-2006 standard.

? Technical Specifications: Quantitative Oxygen supply: 1.52 l/min; automatic supply valve gas supply: 100 L/min, Manual supply valve gas supply: 110 L/min, airbag Volume: 5.2 Liters.

? Mask: Suitable for Asian face, with anti-impact, anti-fog and other functions. Wear a mask to make sure the call is good.

? Cylinder Water Volume: 2.4L, working pressure 200Pa.

? Alarm device: Automatic high pressure air tightness test, quantitative oxygen supply test, at the same time need to have gas cylinder residual pressure alarm and hypoxia alarm. In low-light environments, background light background display is required. A high voltage sensor is required on the pressure relief valve to ensure that an alarm signal can still be issued in the event of a failure of the airway system.

? Each set of oxygen contains four kg of special CO2 adsorbent and cooling agent.
