SPIRAL DUCTS AND FITTINGS (STAINLESS STEEL V2A)
Spiral ducts are also known as spiral ducts. We manufacture the ducts and fittings from galvanised sheet steel or stainless steel (V2A).All fittings are fitted with a rubber lip seal. Both the ducts and the fittings fulfil tightness class D (highest class for air ducts). The spiral ducts are manufactured in accordance with DIN EN 1506 and DIN EN 12237.
A "spiral duct nipple" is requiredto connect two spiral ducts. Moulded parts (bends, T-pieces, Y-pieces, etc.) are inserted directly into the spiral duct. No extra connector is required for this. Two moulded parts are connected to each other with a "spiral duct sleeve".
Stainless steel spiral duct for the installation of ventilation systemsSpiral duct ØD = inner diameterLength 1000 mmMaterial: Stainless steel V2ADesign according to DIN EN 12237Tightness class D according to DIN EN 1507 (highest class of the standard)Intelmann stainless steel spiral duct Application areas: The Intelmann stainless steel spiral duct or spiral seam duct is used for air routing of extract air, outside air, exhaust air and supply air in centralised domestic ventilation or controlled domestic ventilation with heat recovery. The ventilation duct is made of V2A stainless steel. The diameter refers to the inner diameter of the pipe. Connecting the Intelmann spiral ducts in the ventilation system: Nipples or pipe connectors are used to connect the spiral ducts in a ventilation system. Fittings such as bends, branch pieces or T-pieces can be connected directly to the spiral duct. Sockets are used to connect fittings (bends / branch pieces / T-pieces) to each other. A spiral duct is compatible with all other fittings with the same diameter. Two spiral ducts are connected with a nipple.
