Fan Flange

Circular fan flanges for making flanged connections between fans and ductwork. A flanged joint gives a secure, rigid connection that can be unbolted for maintenance — useful wherever a fan may need to be removed for servicing without disturbing the rest of the duct run.

We stock eight sizes to suit common fan and duct diameters:

• 315mm
• 355mm
• 400mm
• 450mm
• 500mm
• 560mm
• 630mm
• 710mm

These diameters line up with the larger fans in our range, including cased axial fans. For a flexible, vibration-reducing connection instead, see our flexible fan connectors. Lead times are shown on each product page, and stocked items ordered by 3pm ship for next-day delivery.
