　　HYZ4Isolated positive pressure oxygen respiratorFair quality, attractive price,HYZ4 positive pressure oxygen respirator for coal minesSatisfactory harvest, my promise, HongyiHYZ4 isolated positive pressure oxygen respiratorWinning by quality benefits mining enterprises. It can be used in any toxic and oxygen deficient environment and hazardous area.

　　1、 HYZ4 isolated positive pressure oxygen respiratorMain purposes:

　　Main purpose: This respirator is mainly used to protect the respiratory organs of mine rescue team members from harmful gases during rescue work; It can also be used for personnel who have received specialized training in fire protection, petroleum, chemical, metallurgical, transportation, shipbuilding, subway, power and other departments to engage in accident handling work in toxic gas environments.

　　2、 HYZ4 isolated positive pressure oxygen respiratorEnvironmental conditions for use:

　　Toxic and harmful gas components in the environment: CO 0-10%; SO2 0～2%； H2S 0～1%； NO2 0～1% CO2 0～； CH4 0～； N2 0～； Floating dust 10g/m3

　　Atmospheric pressure: 70-125KPa;

　　Relative humidity: 0~;

　　Environmental temperature: -20 to+40 ℃

　　3、 HYZ4 isolated positive pressure oxygen respiratorBy fully absorbing the advanced technological characteristics of foreign countries and combining them with the current usage status of coal mines in China, the product structure highlights the advantages of small size, light weight, reliable performance, comfortable wearing, and convenient use and maintenance. Thus, it is more suitable for the needs of rescue team members in narrow underground tunnels. Passed the inspection by the National Coal Mine Explosion proof Safety Mining Equipment Testing Center and obtained the Mining Product Safety Mark Certificate.

　　4、 HYZ4 isolated positive pressure oxygen respiratorThe working principle is that the compressed clean air stored in the gas cylinder is first depressurized by a pressure reducer, and then further depressurized by a gas supply valve to enter the full face hood for the wearer to breathe and use. Its advantages are: adopting an open structure, the exhaled gas is directly discharged into the atmospheric environment, and due to the large gas supply flow, the wearer feels more comfortable breathing; The HYZ4 isolated positive pressure oxygen respirator adopts a positive pressure structure, and the pressure inside the mask is always greater than the external atmospheric pressure, which prevents harmful gases from entering the wearer's respiratory organs and has a high safety factor; It can be repeatedly inflated for use, and the HYZ4 isolated positive pressure oxygen respirator has a relatively low operating cost.

　　5、 HYZ4 isolated positive pressure oxygen respiratorIt consists of four major systems: oxygen supply system, positive pressure respiratory circulation system, safety and alarm system, and shell harness system.

　　6、 HYZ4 isolated positive pressure oxygen respiratorFeatures:

　　The HYZ-4 isolated positive pressure oxygen respirator is a new generation product used for personal respiratory protection. In isolation from the outside world, it can ensure that the supply of oxygen matches the human lung capacity perfectly, with smooth circulation of oxygen, stable and sufficient oxygen supply, timely tracking and capture, comfortable use and wearing, etc. Its characteristics include low respiratory resistance, small weight and volume, long protection time, high stability and reliability, simple structure, and easy disassembly and maintenance, which have been widely recognized.
