Factory wholesale Ventilation Mining - 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.

Product Feature
◈ Designed for both high negative and positive pressure and elbow use.
◈ Spiral reinforced by spring steel wire/individual steel ring (end ring), seams and PVC profile welded airtight, smooth inner surface, low friction loss.
◈ All ducting and fittings are available in an oval shape.
◈ Customization is possible, with a diameter range of 400 mm to 2100 mm.
◈ Flame resistance conforms to EN13501/DIN4102 B1/NFPA701/DIN75200.
◈ Standard length, 5 m, 10 m, 15m or 20m.
◈ The antistatic feature (3×108Ω) is optional. The newly developed water-based material that is used for antistatic surface treatment is an environmentally protective material without VOC emission in processing and use, and is also healthy for workers. It makes the antistatic value stabilize at 3×106Ω.
