凈氣(qi)型通(tong)(tong)風柜(ju)的使用(yong)特性說(shuo)明(ming)：金屬部件：主(zhu)要(yao)材質(zhi)≥1.2mm鍍(du)鋅鋼板，環氧樹脂靜電(dian)噴涂(tu)，覆有(you)耐用(yong)防(fang)化無(wu)鉛涂(tu)層，保持(chi)高光(guang)潔度(du)并降低腐(fu)蝕和濕氣(qi)的影響(xiang)。門板：主(zhu)要(yao)材質(zhi)≥6mm亞克力板，忻州無(wu)管(guan)(guan)道通(tong)(tong)風柜(ju)，耐候性，優(you)異的抗化學品(pin)性能，無(wu)管(guan)(guan)道通(tong)(tong)風柜(ju)生產(chan)廠家，不易老化，無(wu)管(guan)(guan)道通(tong)(tong)風柜(ju)報(bao)價(jia)，無(wu)色透(tou)明(ming)，通(tong)(tong)體透(tou)光(guang)，視覺舒(shu)服，美觀大方。凈氣(qi)型通(tong)(tong)風柜(ju)層板：主(zhu)要(yao)材質(zhi)≥1.2mm鍍(du)鋅鋼板，防(fang)腐(fu)涂(tu)層，抗酸堿，高度(du)可調。

其(qi)特(te)點是(shi)：可根據通(tong)(tong)風(feng)(feng)(feng)(feng)柜(ju)的工作(zuo)需要來啟閉通(tong)(tong)風(feng)(feng)(feng)(feng)機，相(xiang)互不受干(gan)擾，容(rong)易達(da)到預定的效果(guo)，而(er)且比集中(zhong)式(shi)節省能源(yuan)，因為(wei)集中(zhong)式(shi)系統(tong)(tong)，只要一個通(tong)(tong)風(feng)(feng)(feng)(feng)柜(ju)在(zai)使用(yong)，就(jiu)得(de)開動大通(tong)(tong)風(feng)(feng)(feng)(feng)機。分(fen)散式(shi)由于系統(tong)(tong)小，排(pai)風(feng)(feng)(feng)(feng)量也小，阻(zu)力也小，無管道通(tong)(tong)風(feng)(feng)(feng)(feng)柜(ju)廠家，所以通(tong)(tong)風(feng)(feng)(feng)(feng)機的風(feng)(feng)(feng)(feng)量、風(feng)(feng)(feng)(feng)壓不大，躁聲與(yu)振動相(xiang)應也較小。集中(zhong)式(shi)是(shi)把一層樓面或幾(ji)層樓面的的凈(jing)氣型通(tong)(tong)風(feng)(feng)(feng)(feng)柜(ju)組(zu)成(cheng)一個系統(tong)(tong)，或者整個實驗樓分(fen)成(cheng)一二個系統(tong)(tong)。分(fen)散式(shi)是(shi)把一個通(tong)(tong)風(feng)(feng)(feng)(feng)柜(ju)或間的幾(ji)個通(tong)(tong)風(feng)(feng)(feng)(feng)柜(ju)組(zu)成(cheng)一個排(pai)風(feng)(feng)(feng)(feng)系統(tong)(tong)。
