Remark:

1. All seam are closed welding, suspension rib, grommet space 60cm, dual suspension when the diameter ≥1800mm.

2. Plastic zipper coupling, there are sealing extend flap on the both ends to seal the coupling.

3. Accessories specification like suspension ring, coupling can be negotiated if any special requirement.


JULI® 
Railway Tunneling Air Hose Advantages:

 

1. Since 2006, Foresight has more than 10 years experience of manufacturing ventilation duct and ventilation duct fabric, and owns a strong R&D team which consists of over 10 engineers graduated from professional school,  exceeds 30 high-speed rapier looms, 3 laminated production lines, several automatic production lines for pvc ventilation duct, which ensures annual production of rolled film over 10,000 tons, pvc ventilation duct fabric 15,000,000 square meters, pvc ventilation duct 2,000,000 meters (refer to DUNS Certification No.: 526498416). Foresight continues to supply the all kinds of ventilation ducts for ventilation fan company at home and abroad.

 

 

2. HF/hot air welding the suspension rib and duct automatically, uniform and stable seam to avoid the effect of welding stability due to man-made operation, so the efficiency is 2-3 times of traditional welding machine.

 

 

3. Grommet is done by automatic machine to avoid falling off.

 

 

4. The ducts are coupled with 10# engineering plastic zipper. Sewing the zipper on one piece of fabric, then welding the fabric with zipper on the duct, which ensure no any needle eye on the duct, minimized of air leakage, and protection zipper from breakage.

 

 

5. Two repair methods: repair fabric with zipper and Velcro.

 

 

 

6. Several automatic production lines, duct monthly production 20,000 meters, which ensures the short delivery time for large order.

 

 

7. Tracking and inspection in all manufacturing processes, like welding strength, wind pressure of finished duct.

 

 

8. Packing: pallet, woven bags or wooden case, low cost and applicable to long distance transportation.
