Round air duct Spiro f900

Round spiral duct with a diameter of Ø900 made of galvanized sheet metal with a standard length of 3 meters. The spiral winding gives high mechanical strength and reduces the likelihood of deformation. Spiral ducts are preferred in ventilation installations due to their better aerodynamics, which reduces air resistance compared to standard rectangular ducts. They are also very suitable for open installation as they look more aesthetically pleasing. Whether it's for stores, warehouses, or restaurants, they are a preferred choice in most cases.
