QG-HYZ2001 Isolated Positive Pressure Compressed Oxygen Respirator HYZ series 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-playing breath for the workers to rush to deal with an emergency and provide disaster relief. It adopts \"positive pressure” principle to supply oxygen, which makes the pressure in the face mask exceed the atmopheric pressure, so it can efficiently stop harmful gas outside from flowing into the face mask, which assure rescue corps’ safety. Features: (1). Structure is logical, use comfortable and reliable, the installation,test and maintenance are convenient for quick use (2). The design of cases is logical, it is able to endure impact, hermeticity best, performance variable and safe. (4). HYZ2 coolant canister housing equipped with ponding drainage: it avoids engendering resistance. (5). The cooling performance is the best , comfortable. (6). Regulable constant flow unit (patent) : it is regulated according to users’ requirements, invariable for a long time. (7). Demand valve (patent) :oxygen supplied more timely and fully, performance safer. (8). Facemask is equipped with a speaking unit and drainage(patent), use convenient and easy.
