Manufacturer of Twin Ventialtion Duct Duct - JULI® Spiral Ventilation Ducting – Foresight Detail:

Product Informations

JULI^® spiral ventilation duct is made of manganese steel with good elasticity as the reinforced steel wire and can be used under positive pressure for air blowing as an elbow in the underground. It is made by a special welding machine in Foresight with a good appearance and excellent folding performance. During ventilation, the stress is smooth and uniform, and it can bear greater pressure without the danger of blowing. The JULI^® spiral ventilation duct can also be used for negative pressure and exhausting air from a tunnel inside. The reinforced steel wire is made of cold-drawn steel, which can support high air extraction pressure to meet the needs of customers.

The fire resistance of the JULI^® tunnel ventilation duct is DIN4102 B1, NFPA701, EN13501, DIN75200, and all fire resistance is accompanied by an SGS test result. When a fire is present, a high flame retardant can help to limit the hazardous and harmful gases that can injure the human body.
