This is the 10m long Tecflex 400 Uninsulated Flexible Ducting 100mm diameter. Tecflex 400 is ideal for use in high, medium and low pressure air conditioning systems where a quality un-insulated flexible ducting is required.

Tecflex 400 is manufactured from aluminium & polyester film in a multi-ply format to provide a tough yet highly flexible, puncture resistant, ducting. The fabric is supported by an encapsulated high tensile steel wire helix at 35mm pitch. This construction results in a free yet ultra flexible duct in which smooth bends of less than 1.2D radius can be produced. Encapsulation of the wire helix between the inner and outer duct wall provides an exceptionally smooth inner wall resulting in excellent friction loss characteristics and reduced levels of noise generation.

Un-insulated flexible ducting for joints or connections shall be TECFLEX 400. It shall be manufactured from aluminium & polyester film to form a puncture resistant multi-ply laminate supported by an encapsulated high tensile steel wire helix. The duct shall meet the requirements of BS476 parts 6, 7 and 20. In respect of part 20 the duct shall have a fire resistance of not less than 25 minutes. 

Each 10 metre length of duct is individually cartoned & labelled. This production and packing configuration ensures that wastage through scrap is kept to a minimum and dramatically reduces the chance of damage in transit or on site. Storage space required is also kept to a minimum with a 10 metre length being compressed to 500mm.

  • Diameter: 100mm

  • Air Velocity: 30 m/s maximum.
  • Working Pressure: Maximum 2000 Pa positive.
  • Finish: Metallic Silver.
