消防排煙風機首先應該滿足溫度和時間的特性，即國家規定280℃/0.5h；其次，在一般環境溫度下，可以保證有效的排煙控制量。此外還要求消防排煙風機能夠進行周期性的實驗，能夠發現其中的不足，并加以改進；可以適用各種通風要求的管道，便于安裝與使用。消防排煙風機的性能優良、耐高溫性能良好、效率高、占地比離心風機少、高溫性能優良。消防排煙風機能在300℃高溫條件下連續運行60分鐘以上，100℃溫度條件下連續20小時不損壞，高品質配件應用范圍廣，可根據高級民用建筑的不同要求，采用變速或多速的驅動型式，消防排煙風機廣泛應用于高級民用建筑、烤箱、地下車庫、隧道等場合。配件批發安裝(zhuang)(zhuang)方便，可直接和墻(qiang)壁安裝(zhuang)(zhuang)，安裝(zhuang)(zhuang)可采用垂直式(shi)(shi)、水平(ping)式(shi)(shi)或吊裝(zhuang)(zhuang)式(shi)(shi)，很大程(cheng)度上(shang)節省了占(zhan)地面積。

在(zai)空調送風(feng)系(xi)(xi)(xi)(xi)統(tong)中，空調送風(feng)機(ji)送出(chu)的(de)(de)風(feng)必須通(tong)過主干管(guan)(guan)分(fen)配到(dao)(dao)支管(guan)(guan)中；在(zai)排(pai)(pai)煙(yan)(yan)(yan)(yan)系(xi)(xi)(xi)(xi)統(tong)中，煙(yan)(yan)(yan)(yan)氣(qi)由支管(guan)(guan)到(dao)(dao)主干管(guan)(guan)后，進入排(pai)(pai)煙(yan)(yan)(yan)(yan)風(feng)機(ji)排(pai)(pai)出(chu)。當(dang)(dang)建筑物內(nei)發(fa)生火(huo)災(zai)時，在(zai)通(tong)風(feng)、空調系(xi)(xi)(xi)(xi)統(tong)中，為(wei)了(le)(le)防止火(huo)勢通(tong)過送風(feng)系(xi)(xi)(xi)(xi)統(tong)蔓(man)(man)延(yan)，當(dang)(dang)送風(feng)系(xi)(xi)(xi)(xi)統(tong)中氣(qi)體溫(wen)度(du)達(da)到(dao)(dao)70℃時，防火(huo)閥(fa)(fa)機(ji)構(gou)上(shang)(shang)熔斷(duan)器動(dong)(dong)作，閥(fa)(fa)門(men)亦迅速關閥(fa)(fa)，切(qie)斷(duan)煙(yan)(yan)(yan)(yan)氣(qi)與火(huo)勢沿風(feng)管(guan)(guan)蔓(man)(man)延(yan)的(de)(de)通(tong)路。同樣，在(zai)排(pai)(pai)煙(yan)(yan)(yan)(yan)系(xi)(xi)(xi)(xi)統(tong)中，發(fa)生火(huo)災(zai)時，排(pai)(pai)煙(yan)(yan)(yan)(yan)閥(fa)(fa)開啟(qi)，進行排(pai)(pai)煙(yan)(yan)(yan)(yan)，為(wei)了(le)(le)截斷(duan)高(gao)溫(wen)煙(yan)(yan)(yan)(yan)氣(qi)在(zai)排(pai)(pai)煙(yan)(yan)(yan)(yan)管(guan)(guan)路中流動(dong)(dong)，防止火(huo)勢蔓(man)(man)延(yan)到(dao)(dao)另一(yi)防火(huo)分(fen)區，當(dang)(dang)排(pai)(pai)出(chu)的(de)(de)煙(yan)(yan)(yan)(yan)氣(qi)溫(wen)度(du)達(da)到(dao)(dao)280℃時，排(pai)(pai)煙(yan)(yan)(yan)(yan)防火(huo)閥(fa)(fa)、排(pai)(pai)煙(yan)(yan)(yan)(yan)口(kou)上(shang)(shang)熔斷(duan)器動(dong)(dong)作，閥(fa)(fa)門(men)必須自(zi)動(dong)(dong)關閉，阻止排(pai)(pai)煙(yan)(yan)(yan)(yan)。由此可見，防火(huo)閥(fa)(fa)、排(pai)(pai)煙(yan)(yan)(yan)(yan)閥(fa)(fa)做(zuo)到(dao)(dao)了(le)(le)該通(tong)則通(tong)，該斷(duan)則斷(duan)的(de)(de)隔煙(yan)(yan)(yan)(yan)阻火(huo)作用(yong)。
