Pro METU Fast Clamps – Airtight Galvanised Steel

Airtight duct joints, done in seconds

Pro METU Fast Clamps are heavy-duty duct clamps that join inline fans, carbon filters and silencers in a grow tent or grow room extraction run. Loose duct joints leak air and quietly rob a ventilation system of performance, so a fast, genuinely airtight seal matters more than it looks. Made from galvanised steel with an integrated polyethylene foam lining, they seat evenly even when duct sizes differ slightly, and the one-bolt fixing means quick, secure installation every time.

Key Benefits

• Airtight seal between fans, carbon filters and silencers
• Galvanised steel construction for durability and long-term use
• Foam lining seals up to 4mm duct size differences
• One-bolt fixing for quick, reusable installation
• Ideal for joining CarboAir filters directly to fans
• Available in multiple sizes to match common ducting diameters

Losing extraction performance to leaky joints?

Poorly sealed ventilation connections let heat and humidity build back up in the room and drop the efficiency of your extraction, which can trigger humidity problems in flower. A tight clamped joint keeps air moving through the fan and filter as intended, clearing heat and humidity and drawing fresh CO2 in.

How to Use

1. Align the connection flanges of the fan, filter or silencer.
2. Place the METU Fast Clamp around the joint where the two components meet.
3. Check the foam lining sits evenly around the connection.
4. Tighten the single bolt until both components are held firmly.
5. Confirm an airtight seal before running the ventilation system.
