Tecflex 400 is ideal for use in high, medium and low pressure air conditioning systems where a quality uninsulated 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 consruction reults 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. Diameter Range: 80mm to 500mm Temperature Range: From -30 deg C to + 120 deg C Air Velocity: 30 m/s maximum. Working Pressure: Maximum 2000 Pa positive Standard Length: 10 metres |
