Roof exhaust fan wholesale, Ling of air conditioning (certified), exhaust fan

[Fans] new exhaust fan the smoke machine frame using a standard made of steel, and the use of common SCBA cylinders as the main gas source, install the bottom bracket made of spring steel cylinder fixed to avoid friction with the metal cylinder or collision hazard. In using titanium alloy seamless set of gas transmission pipeline turn, is equipped with four high-temperature, high pressure, explosion-proof, waterproof material coupling cylinder valve, the valve is installed on the links integrated modular vacuum , a high pressure switches, pressure gauges, alarm. Use, easy to observe single cylinder pressure is sufficient. If it is found inadequate pressure, high pressure switch can be closed to facilitate the complete replacement of individual cylinders, avoiding downtime replacement cylinders. Compared with the current conventional smoke machine, the biggest advantage of this smoke machine is a fan before and after each of refractory material, before and after the fan interaction, after the blades during rotation, not only played a row smoke effects, also played a role in supercharging, in order to achieve positive pressure exhaust, negative effects of smoking. By testing exhaust fan, the smoke machine maximum flow of positive pressure exhaust 12000m3 / h, the amount of negative pressure smoking 6000m3 / h. Especially for a long time fire and rescue scene smoke or toxic gases for field use, the smoke machine equipped with a special external air supply gas source as a subsidiary. External air supply and exhaust air can be used separately from the machine body, in addition to providing adequate gas supply, but also to avoid direct contact with the firefighters and harmful gases, to ensure the safety of firefighters. HTF fire temperature exhaust axial fan in its basic form is the axial-flow exhaust fan HTF structure, using high temperature motor, arranged a special motor cooling system products by the National Fire Equipment Quality Supervision and Inspection Center GA211-1999 "fire smoke fan high temperature test method "high-temperature test at medium temperature conditions of high temperature 300 ℃ continuous operation more than 60 minutes at a temperature of 100 ℃ continuous operation 20 hours / time is not damaged, can be dual exhaust ventilation. Causes of the fire temperature exhaust fan installed in the well-known two-speed motor, fire temperature exhaust fan generally use the two-speed motor, then what is the reason to install two-speed motor is it? Advantageously survey showed that installation of fire temperature exhaust fan two-speed motor allows for low-speed operation peacetime abstract air ventilation available, such as a fire, once produced, will automatically switch to high-speed run through the electronic control system, within half an hour rapid lifting of smoke gas, so fire inside the safe evacuation of personnel, protect life and property safety of the national and folk. Fire temperature exhaust fan conveying air and other combustion, no degenerate gases for steel exhaust fan special for the inner gas does not promise a sticky substance axial-flow exhaust fan, contained in dust and hard particles is not a rule When to 150mg / m3, for ventilation intake air temperature shall not exceed 80 ℃, when used as a fire, when the flue gas temperature at 280 ℃ can continue to run more than 30 minutes.
