DFBZ-7.1防爆方型壁式軸流風機概述：

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，靠墻側裝有鋁合金防雨百葉，可以防止室外雨水和自然風向室內倒灌。

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

3、根據使用環境不同要求，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。
