Flexible Fan Connector

Flexible fan connectors are short flexible sleeves fitted between a fan and the rigid ductwork on either side of it. They take up minor misalignment between fan and duct, simplify installation, and reduce the vibration a running fan would otherwise transmit along a rigid duct run — one of the simplest ways to take structure-borne noise out of a ducted system.

We stock twelve sizes, from small in-line fans right up to large axial units:

• 250mm, 315mm, 355mm, 400mm
• 450mm, 500mm, 560mm, 630mm
• 710mm, 800mm, 900mm, 1000mm

The larger diameters match our cased axial and plate mounted fans. For rigid bolted connections see our fan flanges. Lead times are shown on each product page, and orders over £400 ex VAT include free UK mainland delivery.
