HYZ series oxygen breathing apparatus is a closed-circuit SCBA used in the contaminated or oxygen-deficient atmosphere, such as mine, fire fighting, chemical industry, petroleum and tunnel and so on. It provides long-time breath for the workers to deal with an emergency and provide disaster relief. It adopts positive pressure principle to supply oxygen, which makes the pressure in the facemask exceed the atmospheric pressure, so it can efficiently stop harmful gas outside from flowing into the facemask, which assure rescues corps safety.
