Semi-rigid Aluminium

Ventilation Ducting  | Flexible Ducting |  Semi-rigid Aluminium



Single layer aluminium flexible duct with a 4mm corrugation depth to allow the duct to be compressed for transportation; duct is supplied in 750mm long boxes and extends to 3m. Stated diameters refer to inner bore size. Overall size is 8mm larger than the internal size.

Semi-rigid duct is easily formed by hand to form bends and offsets. The cross sectional area is maintained through the bends ensuring low airflow resistance. The 'stayput' characteristic of the duct means minimal support is required.

Centre line bend radius:
80mm - 200mm = duct diameter
250mm - 355mm = 1.5 x duct diameter
400mm - 500mm = 2.5 x duct diameter

Operating temperature:

up to 300°C.

Fire resistance
BS476 Part 8 - 15 minutes.
