Flexible exhaust duct is flexible with a small bend radius. It’s also flame retardant and kink-proof. The outer layer consists of aluminum foil laminated PVC film. While the cover is high temp and flame resistant glass fiber cotton. The inner duct is high quality alloy aluminum. The flexible duct hose is then supported by high tension spiral steel wire. Flexible heat ducts are suitable for high, medium and low air condition and ventilation systems. It’s also ideal for hot air ducting.

For the connection between the PVC cover and aluminum hose, we use water-base cement. While that means there will not be solvents in the bond process. As it’s an eco-friendly material, it will never cause pollution. As we know, we are the only supplier who use it.
