順坡敞(chang)開式(shi)自(zi)(zi)然(ran)通(tong)(tong)風(feng)器(qi)是(shi)指垂直于屋脊處順坡布(bu)置無(wu)閥(fa)板的(de)(de)自(zi)(zi)然(ran)通(tong)(tong)風(feng)器(qi)。這類通(tong)(tong)風(feng)器(qi)的(de)(de)主要(yao)特(te)點(dian)是(shi)可(ke)以(yi)24小(xiao)時(shi)不(bu)間斷的(de)(de)對工業(ye)廠房(fang)進(jin)行(xing)換氣。敞(chang)開式(shi)自(zi)(zi)然(ran)通(tong)(tong)風(feng)器(qi)在(zai)我國南(nan)方的(de)(de)利用率(lv)較(jiao)高。因為南(nan)方的(de)(de)氣候特(te)點(dian)，冬季無(wu)需保(bao)溫功能，所(suo)以(yi)較(jiao)多(duo)采用敞(chang)開式(shi)自(zi)(zi)然(ran)通(tong)(tong)風(feng)器(qi)，價格相對啟閉式(shi)自(zi)(zi)然(ran)通(tong)(tong)風(feng)器(qi)來說較(jiao)便(bian)宜。而順坡布(bu)置的(de)(de)自(zi)(zi)然(ran)通(tong)(tong)風(feng)器(qi)還(huan)有(you)個(ge)特(te)點(dian)就(jiu)是(shi)喉口(kou)尺寸(cun)較(jiao)小(xiao)，荷載較(jiao)輕，安裝于屋面，結構。

通(tong)風器優(you)質廠家——麥克威(wei)對(dui)骨架(jia)(jia)防腐(fu)方(fang)面尤其(qi)重(zhong)視，因骨架(jia)(jia)屬于結(jie)(jie)構(gou)件，牽涉到(dao)結(jie)(jie)構(gou)性。矩(ju)管首先除(chu)銹(xiu)后(hou)進行熱(re)鍍(du)鋅(xin)，熱(re)鍍(du)鋅(xin)后(hou)進行骨架(jia)(jia)成型焊(han)(han)接(jie)(jie)，焊(han)(han)接(jie)(jie)后(hou)的(de)骨架(jia)(jia)，焊(han)(han)點(dian)處(chu)(chu)必須進行特殊的(de)防腐(fu)處(chu)(chu)理，這(zhe)樣才能保證骨架(jia)(jia)結(jie)(jie)構(gou)及(ji)通(tong)風器使用壽命(ming)。

對于(yu)高腐蝕(shi)環境中使用(yong)的自(zi)然(ran)(ran)通(tong)風器(qi)，骨(gu)架采用(yong)高防(fang)腐處(chu)理，彩鋼板采用(yong)氟碳(tan)板防(fang)腐。工(gong)業廠房屋面(mian)通(tong)風十分重要,屋頂通(tong)風器(qi)防(fang)腐必(bi)須(xu)重視(shi)，優良的防(fang)腐性能(neng)(neng)才(cai)能(neng)(neng)起(qi)到保障作用(yong)。在防(fang)腐性能(neng)(neng)方(fang)面(mian)，Mcw1型(xing)自(zi)然(ran)(ran)通(tong)風器(qi)和Mcw2型(xing)自(zi)然(ran)(ran)通(tong)風器(qi)這兩款薄型(xing)自(zi)然(ran)(ran)通(tong)風器(qi)就極為不錯，外形美(mei)觀大方(fang)，功能(neng)(neng)實用(yong)，性價比(bi)極高。
