14 ” COMBI DUCT 10 METRE

Description

14-Inch Combi Ducting 10-Metre Roll provides a full 10-metre coil of flexible twin-layer aluminium ducting in the large 350mm (14-inch) diameter, designed for high-volume commercial extraction and ventilation systems that require substantial air movement through a single duct run. At 14 inches in diameter, this ducting is specified for industrial-scale growing operations, large processing or drying rooms, and commercial HVAC applications.

The combi construction — twin corrugated aluminium layers without insulation — makes this the appropriate specification for interior duct runs and warm, dry environments where the primary requirement is structural integrity and flexibility at large diameter rather than thermal insulation. The corrugated twin-layer design maintains the duct’s round cross-section under the substantial suction pressures generated by large commercial fans, preventing the collapse that would occur with single-layer foil duct at this diameter.

The 10-metre roll format provides a practical working length for a single installation run, reducing the number of joints required compared to assembling the same run from multiple short sections. Fewer joints means lower leakage risk and reduced assembly time. Ensure the correct 350mm fixings are to hand before installation. Available at The Horticulture Company alongside commercial-scale fans, carbon filter systems, and the full range of ducting and ventilation accessories for large-format growing operations.
