消防排煙風機及排煙風機：是由風機(ji)(ji)筒子(zi)，電(dian)(dian)(dian)機(ji)(ji)筒子(zi)、葉(xie)輪、電(dian)(dian)(dian)機(ji)(ji)組成(cheng)；現(xian)在(zai)許多客戶買風機(ji)(ji)詢報價，有的(de)同(tong)類(lei)型的(de)風機(ji)(ji)差幾百元(yuan)不等(deng)；那是由于現(xian)在(zai)有些廠家省掉了電(dian)(dian)(dian)機(ji)(ji)筒子(zi)，立式(shi)電(dian)(dian)(dian)機(ji)(ji)改為臥(wo)式(shi)電(dian)(dian)(dian)機(ji)(ji)，直接在(zai)風機(ji)(ji)殼(ke)上焊接個底座，拼(pin)裝而成(cheng)。其次是選用臨清電(dian)(dian)(dian)機(ji)(ji)。故而出現(xian)現(xian)在(zai)同(tong)等(deng)級類(lei)型價位間隔甚大的(de)現(xian)象(xiang)
