Duct with rectangular cross-section
Standard ventilation ducts are made in pieces of following lengths: 1000, 1500, 2000 and 3000mm. The channels are produced as bare (both ends without couplers) and with a connection coupler at one end which allows for easy and quick connection of channels with one another.
The wall thicknesses and potential ribbing depends on the parameters of the air to be transported inside the duct.
