FLAT DUCT AND MOULDED PARTS
The Intelmann flat duct and moulded parts range features an especially slim design. The height of the duct is 50 mm, making it ideal for installation in a filigree ceiling or screed concrete. To ensure the duct can withstand the load, the flat duct must be used with the pre-assembled internal stiffening. Alternatively, the internal stiffening can be purchased separately and inserted into the duct as a DIY task. To connect two flat ducts, a "flat duct connector (nipple)" is required. This is pushed into the ducts. Moulded parts (bends, T-pieces, Y-pieces, etc.) are pushed directly into the duct. No connector is necessary for this. Two moulded parts are connected to each other with a "moulded part connector (coupling)".
Flat trunking made of galvanised sheet steel Width: 100 to 300 mm, height: 50 mm The width and height specifications refer to the internal dimensions of the trunking The total length of the trunking is L = 1000 mm The Intelmann flat trunking system is designed according to the socket-nipple principle Flat ducts are connected to each other with flat duct nipple connectors Moulded parts (bends, T-pieces, transition pieces) are connected to each other with a sleeve This allows all moulded parts to be inserted into the trunking. No further connection is required for this. The flat duct is suitable for a wide range of applications. These range from supply and exhaust air ducts for controlled (domestic) ventilation to use as an exhaust air duct for an extractor bonnet in the kitchen and as a supply air duct for fireplaces or stoves. The duct is suitable for installation under the screed. We recommend our version with internal reinforcement for this purpose. To seal the joints, we recommend our aluminium adhesive tape or aluminium-laminated cold-shrink tape. Both options offer sufficient protection against pressure loss in your pipework system.
