Round ducts

Round ducts


Round ducts are always the best choice to combine with ventilation units or air conditioning systems. This type of duct is the easiest to clean, since they have no corners. Plus, they allow the air to flow perfectly. There are also many accessories available to complete the installation. Contact us via the form below for specific dimensions and orders or download the catalogue.

There are seven different types of curves in the range that are suitable for round channels. Depending on the diameter of the round Galva channel, a corresponding curve is available.

There is a choice between curves of 15°, 30°, 45°, 60° and 90°, depending on the required angle.

There are also short curves which are shorter in length. There is a distinction between ordinary short curves and female/male short curves. Each type of curve is standard equipped with a double EPDM seal.
