Insert duct dimensions 220x80 mm

The galvanised flat duct with dimensions 220x80 mm and a length of 1.5 meters. Fits directly into the fittings, for example a bend or T-piece.

Flat channel ducts are galvanised flat ducts that are integrated into a floor or concrete to allow air distribution or extraction in buildings. These flexible products are designed to be invisible and are commonly used in new construction and renovation projects. Furthermore, a galvanised flat duct can be used in walls, floors and/or ceilings. Combined with a straight galvanised flat duct and various fittings, a ventilation duct can be constructed as required. There are both round and rectangular galvanised flat ducts. Some advantages of galvanised flat ducts are: efficient air stream, space saving, noise reduction and design flexibility.

Product specifications

Our collapse air ducts are specifically designed for use in residential construction and floors equivalent to residential construction. In addition, these durable products are manufactured from high quality galvanized steel. This steel is provided with a corrosion-resistant zinc coating, applied using the reliable Sendzimir process, where a two-sided zinc coating is applied. This guarantees a robust and durable protection against corrosion, in accordance with the NEN-EN 10346 and NEN-EN 10143 standards.

Depending on the dimensions of the air duct, we choose the most suitable sheet thickness to ensure strength and functionality. For galvanised flat ducts in dimensions 170x80 mm, a sheet thickness of 0.5 mm is used, while the larger dimensions such as 220x80 mm mm and 300x80 mm are carried out in a 0.6 mm sheet. The cross connections in rectangular galvanised flat ducts are implemented as sliding connections, using a coupling piece. These joints are securely fastened with self-drilling screws. To prevent water or cement from entering the air duct, the joints are finished with PVC tape. Longitudinal joints are performed in a flanged or spot welded connection. These properties make our galvanized collapsed air ducts a reliable choice for construction projects where durability and quality are paramount.
