China Positive Pressure Air Breathing Apparatus Fire Equipment

Part 1:Product Introduction
Air respirator is a kind of self open respiratory protective equipment, the respirator use masks and around the wearer's face and make the wearer respiratory organs, eyes and facial canister or completely isolated anoxic environment with the outside world, to bring their own supply of compressed air source used by the wearer to breathe clean air, breath directly discharged into the atmosphere. Any respiratory cycle, the pressure in the mask is greater than the environmental pressure, can effectively prevent the external toxic and harmful gas invasion mask, ensure the safe use of personnel.

This product adopts the knapsack structure, using a single 6.8L gas cylinder, equipped with the pressure flat vision device and a half ball type full cover. Respirator overall accord with human body engineering design, reasonable structure, safety performance is high, the operation is convenient, has a wide field of vision, air supply economic, functional and practical, and the advantages of stable performance, for all kinds of poison gas or anoxic environment in high-risk operations personnel.

Air respirator cylinders can be used for up to 90 minutes. In the use of breathing apparatus, please economize on gas, the exhalation frequency is controlled about 10-15 times/min.

Please read this manual carefully before using the product.
Part 2:Use for
Positive pressure fire air breathing apparatus is mainly used for fire officers and soldiers in the fire fighting or rescue to prevent inhaling harmful gases, smoke harmful pollutants, suspended in the air, or used in anaerobic environment. The respirator cannot be used underwater.
Part 3:Main structure

The respirator consists of five parts: cylinder assembly, pressure reducer assembly, full cover assembly, supply valve assembly, and back - back assembly, with a kit, receiving bag and equipment box.
