Tectherm 400 is a high quality fully flexible, factory insulated ducting offering excellent standards of performance. It is suitable for high, medium amd low pressure applications. Tectherm 400 is manufactured using Tecflex 400 as the inner core, wrapped in a 25mm thick high density fibreglass blanket which is overlapped to ensure continuity of thermal insulation. The insulation is then covered by a tough scuff resistant, reinforced aluminium and polyester laminate which acts as a vapour barrier. The use of Tecflex 400 as the inner core completely shields the airstream from the fibreglass insulation. The exceptionally smooth inner wall of the ducting provides for excellent friction loss characteristics and reduced levels of noise generation. This construction results in a highly flexible duct in which bends of 1/2 D radius can be produced. 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 |
