Fast Clamp — Galvanised Steel Carbon Filter Connector for Inline Fans
Best for: Growers who want a simple, tool-free way to connect a carbon filter directly to a duct fan without faffing about with flexi-ducting
Our thoughts
If you're running a ventilation system, this saves you time, money, and headaches. One clamp replaces flexi-ducting and multiple duct clips, and the vibration dampening means less noise. Proper piece of kit.
The Fast Clamp is a galvanised steel connector clamp designed to join a carbon filter directly to an inline duct fan with zero fuss. It's lined with foam or neoprene sealing, tightens with a single 6mm Allen key, and creates an air-tight connection that eliminates the need for flexi-ducting and separate duct clips. Simple, reliable, and it reduces vibration noise into the bargain.
How it compares
This sits in the practical essentials category of ventilation connectors.
- All-in-one solution — replaces flexi-ducting + 2 duct clips in one go
- Faster installation than traditional duct clip setups
- Vibration dampening foam lining reduces fan noise compared to basic hose clamps
- Significantly cheaper than full professional ductwork systems
- Removable design makes cleaning and maintenance straightforward
Compared to generic jubilee clips or basic hose clamps, you're getting a proper seal with acoustic benefits. Compared to flexi-ducting setups, you're saving money and install time.
Usage guidance
Installation is straightforward and takes minutes:
Basic installation
Unwind the bolt using a 6mm Allen key. Open the clamp wide enough to slide it over both the filter flange and the interior of the fan outlet. Once seated over both flanges, turn the bolt clockwise until you achieve a tight, snug join. That's it.
Carbon filter to inline fan connections
This is the primary use case — connect your carbon filter directly to your inline duct fan without any intermediate ducting. Creates an air-tight seal that maintains system efficiency.
Multi-stage ventilation setups
Works equally well joining filters to silencers, or silencers to ducting runs, wherever you need a quick, solid connection.
Maintenance and removal
The removable design means you can disconnect components quickly for cleaning or system adjustments. Just unwind the bolt the same way you tightened it.

Our take
This is one of those accessories that does exactly what it should, day in, day out. It's a straightforward, solid connection that eliminates unnecessary components and reduces install time. You're not paying for features you don't need, and the vibration dampening is a genuine benefit if noise is an issue in your space.
Good time to buy while stock lasts. If you're building a ventilation system or upgrading an existing one, this is worth picking up.
