1) 送(song)(song)風(feng)，包括(kuo)通氣(qi)(qi)，如送(song)(song)鮮風(feng)和排氣(qi)(qi)，這個范圍(wei)很廣，如工(gong)廠車(che)間(jian)，生(sheng)產(chan)場地空氣(qi)(qi)，由(you)于有(you)(you)(you)害氣(qi)(qi)體產(chan)生(sheng)需(xu)要(yao)(yao)排出室(shi)外(wai)(wai)，又(you)需(xu)要(yao)(yao)把室(shi)外(wai)(wai)空氣(qi)(qi)輸送(song)(song)至室(shi)內。這時就(jiu)要(yao)(yao)使用(yong)(yong)流量大(da)而壓力小(xiao)的(de)空氣(qi)(qi)輸送(song)(song)管(guan)道(dao)(dao)，螺旋(xuan)風(feng)管(guan)就(jiu)適用(yong)(yong)，一般(ban)情況下(xia)使用(yong)(yong)鍍鋅(xin)鐵(tie)管(guan)，有(you)(you)(you)腐蝕性及特別(bie)潮濕場所使用(yong)(yong)不銹鋼(gang)管(guan)。2) 送(song)(song)冷風(feng)。常見的(de)是中(zhong)央空調的(de)管(guan)道(dao)(dao)，這種管(guan)道(dao)(dao)需(xu)要(yao)(yao)加保(bao)溫(wen)材(cai)料(liao)(liao)。螺旋(xuan)風(feng)管(guan)可內貼保(bao)溫(wen)材(cai)料(liao)(liao)，外(wai)(wai)表看來(lai)美觀。3) 排油(you)煙(yan)。飯店、酒樓、賓館的(de)廚房均有(you)(you)(you)大(da)量油(you)煙(yan)產(chan)生(sheng)，需(xu)要(yao)(yao)排出，使用(yong)(yong)圓形的(de)風(feng)管(guan)就(jiu)是油(you)煙(yan)囪。在這里(li)，螺旋(xuan)風(feng)管(guan)該叫(jiao)做(zuo)油(you)煙(yan)管(guan)。4) 除塵。有(you)(you)(you)些工(gong)廠生(sheng)產(chan)車(che)間(jian)很多塵埃，需(xu)要(yao)(yao)專(zhuan)門的(de)除塵裝置，其中(zhong)量較大(da)的(de)管(guan)道(dao)(dao)，可使用(yong)(yong)螺旋(xuan)風(feng)管(guan)。5) 散裝物料(liao)(liao)輸送(song)(song)。有(you)(you)(you)些工(gong)廠的(de)生(sheng)產(chan)過(guo)程中(zhong)，需(xu)要(yao)(yao)輸送(song)(song)松(song)散的(de)顆粒，特別(bie)是比重不大(da)的(de)如發泡塑(su)料(liao)(liao)粒之類的(de)使用(yong)(yong)螺旋(xuan)風(feng)管(guan)造價低、效(xiao)果好。
