Fast Clamp Quickly join a Carbon Filter directly to your Duct Fan with a Fast Clamp. Eradicates the need for a length of flexi-ducting and 2 Duct Clips. How a Fast Clamp Works A Fa st Clamp is a wide metal collar, lined with dense foam, which can be tightened around the join between a duct fan and a carbon filter. The collar is tightened with a 6mm allen (hex) key. The strong wide collar forms a very strong mechanical connection between the fan and filter while the thick dense foam makes an air-tight seal between the two.
