DFBZ-7.1防爆方型壁式軸流風(fēng)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(fēng)量、風(fēng)壓，降低風(fēng)機噪聲，風(fēng)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(fēng)機噪聲。風(fēng)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(fēng)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(fēng)機葉輪直徑為250~710mm共10規(guī)格，每一規(guī)格風(fēng)機聽片數(shù)者都為4片，風(fēng)量600~15000m3/h，風(fēng)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(fēng)機葉片數(shù)都為5片，風(fēng)量900~10000m3/h，風(fēng)壓25~210Pa。
3、根據(jù)使用環(huán)境不同要求，A型風(fēng)機可制成BXBDZ型防爆軸流風(fēng)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。
