Product Informations

JULI® antistatic ventilation duct is primarily designed for high concentration gas in the underground, such as coal mines and tunnels. Antistatic duct fabric is treated with a water-based surface material that is environmentally friendly, emits no VOC during processing and use, is safe for workers, and stabilizes the antistatic value at 3×106Ω.

The fire resistance of the JULI® antistatic 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.
