It can provide compressed air for more than 15 minutes, and is supplied by a gas supply valve. The mask is always positive pressure to prevent intrusion of toxic and harmful gases.
The constant current emergency escape respirator consists of a compressed gas cylinder, a pressure reducer, a pressure gauge, a gas conduit, a hood and a backpack, and can provide a constant flow of gas for more than 15 minutes. A pressure gauge on the cylinder always shows the pressure inside the cylinder. The hood or the full cover is equipped with an exhalation valve to discharge the gas exhaled by the user out of the protective cover. Since the gas pressure in the protective cover is greater than the atmospheric pressure of the external environment, the ambient gas cannot enter the protective cover, thereby achieving the purpose of respiratory protection. The device is small in size and can be carried by pe
rsonnel without affecting the normal activities of the person.
