(including TIMBERDUC® 533 – 534)

NORRES AIRDUC® profile hoses have a spring steel wire firmly embedded in the wall and are spiral-welded. They have very smooth interior surfaces, high axial stiffness combined with good flexibility and are lightweight in relation to comparable rubber hoses.
We can adapt the design and characteristics of the hose to meet your specific requirements. This increases the benefit to the customer, creates added value and often reduces costs. Let us know what we can do for you!

  1. Welding:

    • Coherent, secure bonding
    • Gas and liquid tight
    • Partial or complete colouring to meet customer specifications
    • Long welding seam for greater process and operational reliability

  2. Extruded profile hose with a high delivery rate:

    • High smoothness of the interior hose surface
      → less deposition of the delivered material
      → gentler material delivery
    • Section shape is optimized for flow
      → low pressure loss
      → reduction of blower power requirements
      → lower operating costs
    • Reinforced wall at the primary points of wear

  3. Optimized design:

    • High axial stiffness
    • Very flexible
    • Folds evenly

  4. Steel wire:

    • Spring steel wire firmly embedded in the wall
    • No softening of the reinforcement at high temperatures (in contrast to full plastic hoses)
    • Electrically dischargeable by grounding the wire
