Elbow for rectangular air duct with a perimeter of 1200 mm. up to 2700mm.

The fittings are used to change the direction of the main air network, as well as to connect sections to it or to complete it. This can be done by elbows 90 *, 60 *, 45 *, 30 * or tees, as well as any other connecting elements that can be made as needed. The change of the diameter of a given section is done by means of reducing elements (transitions), which change the cross-section of the air duct. Usually plugs are installed at the end of each section as a finishing element. The knee is made in sizes ordered by the customer. The material is galvanized sheet metal, and each side of the openings ends with a European profile for connection to the air duct installation.
