    ALUM & PVC COMBINED NON-INSULATED DUCT

     ( MODEL: ALPV-NOD )

    Aluminum & PVC combined flexible air ducts are specifically produced for discharging welding fumes and dense chemical gases where high mechanical resistance is required.

    This product is produced from multi layer aluminium strengthened with high tension steel spring wire, covered with a nonflammable PVC jacket.

    Aluminium & PVC combined flexible air ducts are also recommended for heating, cooling and air-conditioning systems.

     An important aspect of ALPV-NOD is its non-condensing property. And they are elastic and flexible. They can be easily fitted to circular, oval or rectangular connectors.

    Aluminium & PVC combined flexible air ducts are non-flammable.
