This single-layer aluminium flexible duct features a 4mm corrugation depth, enabling compression for easy transport. Supplied in 750mm sections, it extends up to 3 meters. The specified diameters indicate the internal bore size, with the overall external diameter measuring 8mm larger than the internal dimension.
The semi-rigid duct can be effortlessly shaped by hand to create bends and offsets while maintaining its cross-sectional area, which helps minimize airflow resistance. Its 'stayput' property reduces the need for additional support during installation.

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.
