Product Informations

Foresight conducts independent research and development of high-quality PVC flexible ventilation duct membrane compositions that can be customized based on season, application, and performance to provide product quality stability, cost-effectiveness, extended service life, and environmental adaptability.

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.

The automatic production line independently developed by Foresight can realize the production of duct sections with lengths of 100 m, 200 m, and 300 m, including welding suspension fin/patch, welding duct body, folding, etc., which greatly improves the production efficiency and reduces the air leakage rate of the tunnel ventilation duct.
