HTF-A型軸流消防排煙風(fēng)機(jī)用于有消防要求的建筑物，如地鐵、隧道、高層建筑、體育館、地下商場、車間、烘箱等場合的消防排煙和通風(fēng)換氣。一般采用雙速電機(jī)，平時(shí)低速運(yùn)行作通風(fēng)換氣用，如一旦發(fā)生火災(zāi)，通過電控系統(tǒng)自動切換成高速運(yùn)行，在半小時(shí)內(nèi)迅速排除煙氣，使火場內(nèi)人員安全撤離，保護(hù)國家和人民的生命財(cái)產(chǎn)安全。 輸送空氣和其它不自燃,對鋼材無腐蝕性氣體，氣體內(nèi)不允許有粘性物質(zhì)，所含的塵土及硬質(zhì)顆粒物不大于150mg/m3，作通風(fēng)換氣時(shí)進(jìn)氣溫度不得超過80℃，作消防用時(shí)，煙氣溫度應(yīng)在280℃時(shí)能連續(xù)運(yùn)30分鐘以上。
Htf-a axial flow fire smoke exhaust fan is used for fire smoke exhaust and ventilation in buildings with fire protection requirements, such as subway, tunnel, high-rise building, gymnasium, underground shopping mall, workshop, oven and so on. Generally, the two speed motor is used to operate at low speed for ventilation. In case of fire, it will be automatically switched to high-speed operation through the electric control system to quickly remove the smoke within half an hour, so as to safely evacuate the personnel in the fire site and protect the life and property safety of the state and people. Conveying air and other non spontaneous combustion, no corrosive gas to steel, no viscous substances are allowed in the gas, and the dust and hard particles contained in the gas shall not be greater than 150mg / m 3， During ventilation, the inlet temperature shall not exceed 80 ℃. When used for fire fighting, the flue gas temperature shall be 280 ℃ and can be operated continuously for more than 30 minutes.
