POSOTIVE PRESSURE RHZYN240HYZ4

Product introduction:

The positive pressure oxygen respirator is a long-term working personal protective equipment developed and produced by the scientific researchers of our company according to the physiological conditions of Chinese mine rescue team members and the geological conditions of mine production. It is suitable for the coal mine and mine disaster relief environment. It is a closed circulatory device for human respiration and protection with carbon fiber cylinder carrying compressed oxygen as the gas source. It can provide internal circulatory oxygen supply for more than 4 hours for the operators who wear it, completely isolate the external ambient air, and play an absolute role in respiratory protection.
This product fully absorbs the advanced features of similar products at home and abroad. The main outstanding features in the design are: compact structure, comfortable wearing, small volume, large air chamber, light weight, simple disassembly, convenient use, etc. And the enterprise has applied advanced production technology and management mode, thus ensuring the beauty and durability of this product. It is an essential human protective equipment for mine rescue team members, special fire service officers and special engineering technicians to carry out rescue work under the harsh environment of severe pollution, unclear type of toxic gas or oxygen deficiency.
