1、葉輪采用寬葉片大弦長、空間扭曲、傾斜式葉形，可在低速時達到所需風量、風壓，降低風機噪聲，風機機殼外層方形，內(nèi)層為多孔消聲板，夾層為消聲棉，可進一步降低風機噪聲。風機安裝于墻體內(nèi)，靠墻側(cè)裝有鋁合金防雨百葉，可以防止室外雨水和自然風向室內(nèi)倒灌。

2、根據(jù)電機不同可分為A型和B型，A型為普通電機，風機葉輪直徑為250~710mm共10規(guī)格，每一規(guī)格風機聽片數(shù)者都為4片，風量600~15000m3/h，風壓40~160Pa；B型為外轉(zhuǎn)子電機，具有更小的噪聲和重量，見機葉輪直徑由250~630mm共9個規(guī)格，每一規(guī)格風機葉片數(shù)都為5片，風量900~10000m3/h，風壓25~210Pa。

3、根據(jù)使用環(huán)境不同要求，A型風機可制成BXBDZ型防爆軸流風機，可適用于非腐蝕的含有易燃、易爆氣體的場所，防爆等級為EXDllBT4。

二、XBDZ-2.5方形壁式軸流風機適用范圍：

XBDZ系列風機采用模壓鋁合金葉輪，低噪聲風機專用電機直聯(lián)傳動；整機制成方形，外形美觀，墻體預留方孔，安裝方便；出風口裝有自垂百葉， 以防止室外雨水和自然風向室內(nèi)倒灌；具有明顯的安裝牢固、振動小、噪聲低、 運行平穩(wěn)等優(yōu)點，廣泛適用于工礦企業(yè)，民用建筑、館、各種娛樂場所的壁式排風。
