Spiro duct 100mm - length 3m - galvanized steel

Round spiral duct made of galvanized steel (also called galva duct, spiral tube or spiro tube). These metal round ducts are used for the supply and evacuation of ventilation air, and are the ideal choice for a responsible design of your ventilation system. The advantages are a lower air speed due to the round, smooth inner wall and therefore a lower pressure loss.  Suitable for domestic, tertiary and industrial applications.

The M-SAFE range includes a full range of circular ducts and fittings for building a professional and compliant ventilation system. The fittings are provided with a rubber seal to obtain an airtightness class D (tested according to the standards EN12237, EN1507 & EN12599). The quality of the zinc coating of the sheet steel is 275g / m² (= class Z275) and the products have a corrosion category C2.
