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。由于排煙管道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，值得信賴的排煙管道從排氣(qi)口排出(chu)。因氣(qi)體(ti)在葉(xie)(xie)輪(lun)內(nei)的流(liu)動主要是(shi)在徑向(xiang)平面內(nei)，故又稱(cheng)徑流(liu)風(feng)機。離(li)心風(feng)機主要由葉(xie)(xie)輪(lun)和機殼組(zu)成，小型風(feng)機的葉(xie)(xie)輪(lun)直接(jie)(jie)裝在電動機上中、大(da)型風(feng)機通過聯軸器或皮帶輪(lun)與電動機聯接(jie)(jie)。離(li)心風(feng)機一般為單(dan)側(ce)進(jin)氣(qi)，用單(dan)級葉(xie)(xie)輪(lun)；流(liu)量大(da)的可雙側(ce)進(jin)氣(qi)，用兩個(ge)背靠背的葉(xie)(xie)輪(lun)，又稱(cheng)為雙吸式(shi)離(li)心風(feng)機。
