風機廣泛地應用于各個工業部門，一般講，離心式風機適用于小流量、高壓力的場所，而軸流式風機則常用于大流量、低壓力的情況，防火閥價格應根據不同的情況選有不同的風機分類。1鍋爐用風機,鍋爐用風機根據鍋爐的規格可選用離心式或軸流式。又按防火閥它的作用分為鍋(guo)爐(lu)風機(ji)—向鍋(guo)爐(lu)內輸(shu)送空(kong)氣(qi)；鍋(guo)爐(lu)引風機(ji)把鍋(guo)爐(lu)內的煙氣(qi)抽走。2通(tong)(tong)風換(huan)氣(qi)用風機(ji),這類風機(ji)一(yi)般是供工(gong)廠及各種建筑物通(tong)(tong)風換(huan)氣(qi)及采(cai)暖通(tong)(tong)風用，要求壓力(li)不(bu)高(gao)，但噪聲要求要低，可(ke)采(cai)用離(li)心式或軸流式風機(ji)。
