Brief introduction to positive pressure fire-fighting oxygen breathing apparatusRHZYN240 positive pressure fire-fighting oxygen breathing apparatus meeting GA632-2006 standard that we research and develop fully takes up advantages of similar products at home and abroad and particularly reflects small volume, light weight, reliable performance and comfortable to adorn on product mix design combining the physical truth of our country’s ambulance corps. In addition, it’s suitable for ambulance members to be use under mine, tunnel and strait conditions. Positive pressure oxygen breathing apparatus can operate at any poisonous and anoxic surroundings and danger zone.

Traits and purpose of positive pressure oxygen breathing apparatusTrait: RHZYN240 positive pressure fire-fighting oxygen breathing apparatus is a new generation of product that is used for personal breathing protection. Under the condition that is being isolated from outside world, it can ensure that supply quantity of oxygen matches human’s pulmonary perfectly. It has such traits as smooth cycling air circuit, stable and sufficient air supply, timely following supply and comfortable adorning etc. small breathing resistance, small volume and weight, long protection time, high stability and reliability, simple structure, convenient to dismantle and repair, being widely accepted.
