Fast Clamps

Fast clamps are quick-release clamps for connecting in-line duct fans to circular ducting. Instead of screwed or riveted joints, a fast clamp lets you drop a fan in or out of the duct run in moments — which makes routine cleaning, servicing or fan replacement dramatically easier, especially in kitchen extract and other systems that need regular access.

We stock ten sizes covering the common in-line fan diameters:

• 100mm, 125mm, 150mm, 160mm
• 200mm, 250mm, 300mm, 315mm
• 355mm, 400mm

These sizes pair naturally with our inline fans, which span the same diameter range. See the rest of our fitting accessories for flanges and flexible connectors. Stocked items ordered by 3pm ship for next-day delivery.
