JULI® Antistatic Ventilation Duct

JULI® Antistatic Ventilation Duct

There are no VOCs produced during processing or use, making it environmentally friendly.

 

The JULI® antistatic ventilation duct is widely used underground with high concentrations of gas. The antistatic properties of the fabric can prevent static electricity from accumulating on the surface of the fabric to form sparks and cause fires. The ventilation duct will bring fresh air from outside and exhaust turbidity air and diluent toxic gases from the underground.

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 3x106Ω.

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.

Automatic suspension fin/patch, fabric joining, duct body welding, the welding seam is even and stable, decreasing the influence of human factors on welding stability. The welding efficiency is 2-3 times that of a traditional welding machine, and the lead time is reduced.

The eyelets are automatically buckled by the automatic machine to prevent them from falling off.

The antistatic ventilation duct's basic connections are zippers and Velcro. The extra fabric on which the zipper/Velcro is sewed is welded to the flexible duct body to ensure that there are no sewing needle eyes throughout the ducting, reducing air leakage. The long selaing face sleeve covers the zipper or Velcro, reducing the risk of bursting.

Flexible repair methods include glue, zipper repair band, Velcro repair band, and portable hot air gun.
