Each 10 metre length of duct is individually cartoned, this packing configuration ensures that wastage through scrap is kept to a minimum as it can be cut to measure which 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 590mm.

Tecflex 400 is ideal for use in high, medium and low pressure air conditioning systems where a quality uninsulated flexible ducting is required. Construction Tecflex 400 is manufactured from aluminium and 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 ‘sag free’ yet ultra flexible duct in which smooth bends of less than 1/2 D 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. Manufactured from aluminium and 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 and 7.
