風機分類可以按氣體流動的方向，分為離心式、軸流式、斜流式和橫流式等類型。這種風機分類的機器有：離心風機工作時，動力機(主要是電動機)驅動葉輪在蝸形機殼內旋轉，空氣經吸氣口從葉輪中心處吸入。由于電動防火閥葉片對氣體的動力作用，氣體壓力和速度得以提高，并在離心力作用下沿著葉道甩向機殼，高品質電動防火閥從排氣口(kou)排出。因(yin)氣體在(zai)(zai)葉輪(lun)內的(de)流(liu)(liu)動(dong)主(zhu)要是在(zai)(zai)徑向(xiang)平面(mian)內，故又稱(cheng)徑流(liu)(liu)風(feng)機(ji)。離心風(feng)機(ji)主(zhu)要由葉輪(lun)和(he)機(ji)殼組成(cheng)，小(xiao)型(xing)風(feng)機(ji)的(de)葉輪(lun)直接裝在(zai)(zai)電動(dong)機(ji)上中(zhong)、大型(xing)風(feng)機(ji)通過聯軸器或皮帶輪(lun)與電動(dong)機(ji)聯接。離心風(feng)機(ji)一般(ban)為單側進氣，用單級葉輪(lun)；流(liu)(liu)量大的(de)可雙側進氣，用兩個背(bei)靠(kao)背(bei)的(de)葉輪(lun)，又稱(cheng)為雙吸式離心風(feng)機(ji)。
