流(liu)線型屋頂通風(feng)器可(ke)(ke)布置在順坡或屋脊部位(wei)，可(ke)(ke)根(gen)據(ju)(ju)通風(feng)采(cai)光要求設計(ji)(ji)，依據(ju)(ju)防(fang)雨板(ban)(ban)的選用材質可(ke)(ke)設計(ji)(ji)為(wei)采(cai)光型、保(bao)溫型等，如：彩鋼板(ban)(ban)、保(bao)溫板(ban)(ban)、采(cai)光板(ban)(ban)等；可(ke)(ke)選配啟(qi)閉(bi)閥板(ban)(ban)設計(ji)(ji)為(wei)開(kai)敞式或啟(qi)閉(bi)式（可(ke)(ke)開(kai)啟(qi)）通風(feng)器，閥板(ban)(ban)可(ke)(ke)根(gen)據(ju)(ju)需要設計(ji)(ji)為(wei)手動、電(dian)動、消防(fang)聯(lian)動式等控制方式。

流線(xian)型(xing)通風器(暗扣式)可安裝(zhuang)于(yu)順坡及屋脊(ji)部位，是(shi)由(you)(you)骨(gu)架、外(wai)護板(ban)(ban)、防(fang)雨(yu)板(ban)(ban)、排水槽(cao)、閥板(ban)(ban)、電(dian)動(dong)(dong)或(huo)手動(dong)(dong)執行器組成。閥板(ban)(ban)開關采(cai)用(yong)電(dian)動(dong)(dong)或(huo)手動(dong)(dong)控(kong)制，其骨(gu)架由(you)(you)型(xing)材焊接，防(fang)雨(yu)板(ban)(ban)采(cai)用(yong)彩板(ban)(ban)或(huo)采(cai)光板(ban)(ban)（FRP）制作。流線(xian)型(xing)構造，體積較大(da)，通風量較大(da)。

整體(ti)骨架(jia)式流線(xian)型(xing)自然(ran)通(tong)風器一般采(cai)光(guang)順坡式布置(zhi)。其骨架(jia)采(cai)用熱鍍(du)鋅鋼板整體(ti)模(mo)壓成型(xing)，骨架(jia)上壓制(zhi)凹凸花紋提高機械長度，具有良好(hao)的(de)機械性能及(ji)抗腐蝕能力，兼具通(tong)風與采(cai)光(guang)雙重(zhong)功能。
