Ventilation coupling 125 connects shaped products made of galvanized steel to each other. Relatively speaking, this is a small section of straight air duct with a diameter slightly larger than the diameter of the product being connected. It is one of the connecting elements of the Spirovent air duct system to form an aerodynamic ventilation network.
Installation
Shaped products are inserted inside the coupling directly up to the limiting edge. The places where the surfaces come into contact are sealed with sealant or sealant. The joints must be treated with aluminum mounting tape.
