RHZFK Positive Pressure Fire Oxygen Respirator

1 Overview

RHZFK positive pressure fire oxygen breathing apparatus ( see Figure 1), also known as positive pressure fire oxygen breathing apparatus. The oxygen breathing apparatus adopts a new-type normal-temperature refrigerant efficient cooling system, an integrated modular rapid filling of a carbon dioxide absorbent, and a smart multifunctional electronic alarm and the like, as compared with the conventional domestic and foreign similar oxygen breathing apparatus. The performance has been improved and the structure of the whole machine has been optimized. This ensures that the user can work in a hazardous environment for more than 4 hours of breathing , the suction temperature does not exceed 34~C , and the oxygen supply is adequate, and it is lightweight and comfortable to use. It is easy to use and maintain.

RHZFK positive pressure fire oxygen breathing apparatus as an important respiratory protection equipment, a wide range of uses, can successfully replace the current sales and use of similar traditional oxygen breathing apparatus products in China, upgrading our country in this field of technical equipment level.

2 product features

(1) The whole set of equipment passed the high-temperature explosion-proof test, and the 1 000 % flame was intact after 8 s .

(2) The optional intelligent digital display electronic pressure Gauge system can fully protect the safety of fire officers and rescuers. The system includes: digital display of residual cylinder pressure, sound and light alarm, movement status monitoring and active call for help, environment Temperature monitoring; safe and reliable testing in simulated combat environments.

(3) The whole filling technology of the clean can absorbent is convenient and quick, which solves the problem of slow filling speed, powdered absorbent, and dust blowing in the current filling of similar products, reducing the respiratory resistance and increasing the suction. Gas comfort.

(4) It adopts spherical large-field anti-fog and wear-resistant mask, which has clear vision, and the visual field rate is more than 93 % without deformation. The anti-fogging, high-temperature and abrasion-resistant treatment is adopted to effectively solve the current anti-fog spraying of similar products. Agents and installation of anti-fog brush defrost drawbacks.

3 Scope of application

The breathing apparatus is mainly used for fire or rescue personnel at the scene of smoke, gas, steam and oxygen deficiency hazardous environmental disasters, long engaged in disaster relief, rescue, personal respiratory protection when searching for T exploration and so on.

4 working principle

The oxygen breathing apparatus utilizes the gas exhaled by the wearer to enter the clean can through the expiratory hose to react with the absorbent, remove the carbon dioxide, enter the air bag, mix the oxygen released from the oxygen bottle in the air bag, and then cool the new cooler. After using the suction hose for the wearer to breathe. The entire respiration process is always in a one-way cycle and completely isolated from the outside world. It effectively protects firefighters and accident rescuers in the fire, toxic and harmful gases and Other dangerous environments, up to 4 hours of respiratory life safety requirements, and its principle See Figure 2 .
