SPIRAL DUCTS AND VENTILATION DUCTS
Spiral duct for the installation of ventilation systemsSpiral duct ØD = inner diameter [mm]Length 1000 mmMaterial: Galvanised sheet steelDesign in accordance with DIN EN 12237Tightness class D according to DIN EN 1507 (highest class of the standard)Intelmann spiral duct Application areas: The Intelmann 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 galvanised sheet steel. The diameter refers to the internal diameter of the duct. 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.

Slide-in backflow flap / internal non-return flap Nominal width 100 mm to 200 mm Opens smoothly, low pressure loss Closes securely, without noise, without rattling The damper is inserted into the ventilation duct For vertical and horizontal installation Housing: Galvanised steel Damper blade: Aluminium Shaft and spring: Stainless steel The non-return damper is used in round ventilation ducts to prevent air backflow. The casing is made of galvanised sheet steel. The damper blades are made of aluminium and the shaft and spring are made of stainless steel. The internal rubber seal reduces noise. The outer foam strip provides a good seal and secures the non-return flap in the pipe. The non-return damper is designed for operation at ambient temperatures up to 60°C, for the transport of clean air, free of coarse dust, grease, chemical vapours and other impurities.

Insulated spiral duct made of galvanised sheet steelDouble-walled, insulated spiral ducting provides effective protection against condensation.Designed in accordance with DIN EN 12237 and DIN EN 1506Condensation is the main cause of moisture damage in buildings and occurs wherever warm air meets cold surfaces. This can be the case, for example, with a fresh air supply in winter or exhaust air from a heat exchanger. Material: galvanised sheet steelLength: 1 metreInsulation thicknesses: 15 mm| 25 mm | 50 mmMake: Intelmann Possible applications:Outdoor and exhaust air ductTo prevent condensation on the outside of the pipework, the duct must be encased in insulation. An insulation thickness of approx. 15 mm may be sufficient here.Supply and return air ducting through cold roomsHere, the ducts must be protected against heat loss and condensation must be prevented from forming on the inside of the exhaust air duct. The insulation thickness depends on the ambient temperature. If the temperature is outside ( uninsulated attic), an insulation thickness of 50 mm should be selected. In unheated rooms ( unheated cellar), the insulation thickness of 25 mm can be used.
