Product Description
Positive pressure fire fighting air respirator (equipped with communication mask + intelligent pressure gauge and pressure leveling device) can prevent firefighters and emergency rescue personnel from inhaling toxic and harmful gases and dust particles during fire fighting or emergency rescue. It can also be used in oxygen-deficient environments such as chemical accident leakage, chemical industry, petroleum, cold storage, shipbuilding, smelting, electricity, laboratory, mining, gas mining and transportation, so as to effectively carry out fire fighting, emergency rescue and special labor operations. Two of the advantages are combined in dual mode. The communication function can be connected to an external intercom to achieve long-distance communication of at least 1,000 meters, with clear and loud sound quality and smooth conversation. The fast charging device reduces the frequency of gas cylinder replacement, shortens the emergency response time, and greatly improves the rescue efficiency.
Product Advantages:
1. Gas cylinder and self-locking cylinder valve:
Gas cylinder: Made of high-strength aluminum alloy liner and fully wrapped carbon fiber composite material, it is light and strong and not easy to burst. Self-locking gas cylinder valve design, right-hand self-locking double-sided with meter, can ensure that it will not be accidentally closed after opening, and can avoid closing the gas cylinder valve due to accidental collision or misoperation during use.
Gas cylinder flame retardant protective cover: Made of high-grade flame retardant fabric, flame retardant and wear-resistant, with fluorescent strip design and quick pull rope design, and the continuous burning time is ≤5S.
Right-hand self-locking double-sided with meter cylinder valve: The opening direction of the gas cylinder valve is counterclockwise. The gas cylinder valve can be guaranteed not to be accidentally closed after opening. The gas cylinder valve must be rotated twice to open, which can avoid closing the gas cylinder valve due to accidental collision or misoperation during use. The hand wheel needs to be pressed when the gas cylinder valve is closed. The gas cylinder valve is equipped with a safety diaphragm with a bursting pressure of (37-45) MPa, which can prevent the gas cylinder from deforming or bursting due to excessive internal pressure.
2. HG800b2 full face mask:
Polycarbonate spherical full face mask, strong and impact-resistant, wide and clear field of vision, anti-fog and high light transmittance, the light transmittance can reach more than 90%, providing the wearer with clear visual effects and convenient for use in toxic gas environments.
The mouth and nose mask is made of safe silicone material, which is wear-resistant, soft and skin-friendly, and more comfortable to wear.
The full face mask is equipped with laces and lace clips, which can make the wearer's face fit with the double-sheet sealing ring to protect safe and reliable airtightness. The hood is mesh-shaped and connected to the face window in a four-point support manner, providing it with a very comfortable and convenient feeling, and the wide and tight belts can be adjusted.
3. Air supply valve:
Small size, easy operation, large flow, easy to breathe. The air supply valve is equipped with an automatic balancing system, which automatically tracks the breathing action of the person, realizes on-demand air supply, and ensures that the pressure in the mask is higher than the ambient pressure. The square red button on the front of the air supply valve can close the output airflow of the air supply valve and stop the air supply. The circular green button at the bottom of the air supply valve has the following functions:
A If the air supply valve does not open automatically when you inhale hard, press this button to supply air;
B When the mask is fogged, press this button to defog;
C When the wearer feels that the gas supply is insufficient, press this button and the air supply valve will increase the gas supply;
D It can release the residual gas pressure in the medium-pressure pipe, which is convenient for detection and quick disassembly of the quick connector.
4. Decompression assembly:
The decompression assembly (ordinary version) is mainly composed of seven parts: pressure reducer, safety valve, medium-pressure pipe, high-pressure pipe, alarm device, quick connector, and pressure gauge;
| Pressure reducer performance |
Input pressure 0~30Mpa |
Output pressure: 0.5-0.9MPa |
| Safety valve performance |
Opening and full discharge pressure: 1.0-1.53MPa |

Air leakage under 20MPa ≤25L/min |
5. Electronic pressure gauge and HUD display device: The electronic pressure gauge integrates a mechanical pressure gauge, an electronic digital display, an electronic alarm, and a pressure head-up transmitter. The pressure head-up transmitter is an electronic system composed of a pressure sensor and electronic components, which can detect the pressure of a gas cylinder and transmit wireless signals to the pressure head-up display device.When there is air pressure input, the pressure head-up transmitter will automatically turn on and wake up the HUD to start pairing. When the use ends or there is no air pressure input, the pressure head-up device will automatically turn off. The display content of the LCD screen is: gas cylinder pressure display, breathing pressure display, temperature display, battery level display, pairing signal display, timer display, etc. Pressure head-up display device: referred to as HUD, which is installed in a full-face mask and can transmit data such as the pressure of the empty exhalation bottle, the remaining air volume, and the use time displayed by the smart pressure gauge to the HUD pressure head-up device via Bluetooth for light prompts, effectively avoiding the delay in rescue time due to looking down at the pressure gauge, which affects attention.
| 10-30Mpa: The green light is always on |
6-10MPa: the yellow light is always on below |
6MPa: the red light is shining |
