風機是依靠輸入的機械能，提高氣體壓力并排送氣體的機械，它是一種從動的流體機械。風機是我國對氣體壓縮和氣體輸送機械的習慣簡稱，通常所說的風機包括通風機，鼓風機，壓縮機以及羅茨鼓風機，離心式風機,回轉式風機,水環式風機,但是防火閥價格不包括活塞壓縮機等容積式鼓風機和壓縮機。氣體壓縮和氣體輸送機械是把旋轉的機械轉換為氣體壓力能和動能，并將氣體輸送出去的機械。風機主要由風葉、百葉窗、開窗機構、電機、皮帶輪、進風罩、內框架、機殼、安全網等部件組成。開機時由電機驅動風葉旋轉，并使開窗機構打開百葉窗排風。防火閥停機時百葉窗自(zi)動關閉。風機廣泛(fan)用(yong)于(yu)工廠、礦井(jing)、隧道、冷(leng)卻塔、車輛、船(chuan)舶和(he)建筑物的通風、排塵和(he)冷(leng)卻；鍋(guo)爐(lu)和(he)工業爐(lu)窯的通風和(he)引風；空氣(qi)調(diao)節設(she)備(bei)和(he)家用(yong)電(dian)器(qi)設(she)備(bei)中的冷(leng)卻和(he)通風；谷(gu)物的烘干和(he)選送；風洞風源(yuan)和(he)氣(qi)墊船(chuan)的充氣(qi)和(he)推進等。
