Galvanized air duct 315 mm is used in ventilation systems to move air. This air duct is supplied 1 meter long. It is connected directly to other air ducts without nipples or couplings.
The effectiveness of using air ducts is due to several factors: firstly, the high aerodynamic characteristics of spiral-wound air ducts, secondly, the advantages of installation: installation of such air ducts is carried out simply and quickly from straight sections and shaped elements. Thanks to the high quality of connections, designs of shaped elements and tightness, air leakage, pressure losses in the network are reduced and noise characteristics are improved.
The tightness of all products corresponds to class “P” (tight), the air duct system can withstand constant air flow pressure up to 3000 Pa and a single pressure drop of the air flow up to 5000 Pa.
Shaped products are connected using a coupling. Air ducts and fittings are made of galvanized steel with a thickness of: p=0.55 (section from 100-355 mm).
