消防排煙機一般是采用離心式風機和軸流式風機兩種重要的型式。從消防排煙風機風量、風壓考慮來看，消防排煙風機是高比轉高效率的風機，更加的適合選用軸流風機。軸流式消防排煙風機有兩種設計型式，一種為電機與主氣流分離型式，另一種為電機置于主氣流之中。成都通風管道根據煙氣溫度的不同，采用不同型式的消防排煙風機，溫度大于400℃時，采用電機與主氣流分離型式，溫度小于400℃大于150℃，兩種型式的電機都可以選擇，在溫度小于150℃的時候，采用電機置于主氣流之中。 軸流消防排煙風機的流量范圍從7200m？/h至110000m？/h，有不同型號的編制，通風管道用(yong)來滿足(zu)(zu)不(bu)同(tong)通(tong)風(feng)(feng)(feng)排(pai)(pai)(pai)煙(yan)流(liu)量(liang)(liang)的(de)需求。消(xiao)(xiao)防(fang)排(pai)(pai)(pai)煙(yan)風(feng)(feng)(feng)機(ji)可以(yi)根據(ju)壓力(li)(li)情況的(de)不(bu)同(tong)分為(wei)兩種(zhong)類型，一類為(wei)軸流(liu)式消(xiao)(xiao)防(fang)排(pai)(pai)(pai)煙(yan)機(ji)，其各機(ji)號(hao)的(de)壓力(li)(li)在600Pa左(zuo)右，另一類為(wei)斜(xie)流(liu)消(xiao)(xiao)防(fang)排(pai)(pai)(pai)煙(yan)風(feng)(feng)(feng)機(ji)，各機(ji)號(hao)的(de)壓力(li)(li)在1000Pa左(zuo)右。為(wei)了(le)滿足(zu)(zu)排(pai)(pai)(pai)煙(yan)量(liang)(liang)和通(tong)風(feng)(feng)(feng)換氣的(de)要求，消(xiao)(xiao)防(fang)排(pai)(pai)(pai)煙(yan)風(feng)(feng)(feng)機(ji)一般都(dou)設計了(le)雙速(su)型的(de)結構模(mo)式。低(di)速(su)可以(yi)通(tong)風(feng)(feng)(feng)使用(yong)，高速(su)可以(yi)排(pai)(pai)(pai)放(fang)煙(yan)霧，這樣不(bu)但可以(yi)節約能源(yuan)同(tong)時又降低(di)了(le)噪聲污染。
