Air duct for purification air conditioning system: galvanized sheet, stainless steel; However, fiberglass and composite materials that may cause dust source pollution are prohibited
通風管道在安裝前的準備工作也是非常重要的，一定要保證管道內(nèi)外表面整潔；檢查其平整和水平度，吊裝前先要核對現(xiàn)場結(jié)構(gòu)預(yù)留孔洞的位置、尺寸、標高,并將風管內(nèi)外擦拭干凈。
The preparation of the ventilation duct before installation is also very important, and the internal and external surfaces of the duct must be kept clean; Check its flatness and levelness. Before hoisting, check the position, size and elevation of the reserved holes in the site structure, and wipe the inside and outside of the air duct.
風管在安裝時也要注意：管道和配件可拆卸的接口,不得裝設(shè)在墻和走道樓板內(nèi)；支、吊、托架的預(yù)埋件，埋入部分不得油漆,。支、吊、托架不得在風口、閥門、檢視門外設(shè)置。吊架不得直接吊在法蘭上。防火閥、電動風閥等部件單獨設(shè)吊支架。
Attention shall also be paid when installing the air duct: the detachable interfaces of pipes and fittings shall not be installed in the wall and walkway floor; The embedded parts of supports, hangers and brackets shall not be painted,. The support, hanger and bracket shall not be set outside the air outlet, valve and inspection door. The hanger shall not be directly hung on the flange.
