Clivex Combiduct 3 m with Clamps – Combi Flexible Ducting for Air Extraction

Frequently asked questions

• What is the 3 m Clivex Combiduct?

  It is a flexible combi duct that joins aluminium foil with polyester over a spiral steel core. The result is a duct that is more flexible and lighter than a pure double-layer aluminium one, and considerably cheaper. It is ideal when you need to move air along runs with bends.

• Are the clamps included?

  Yes, this 3-metre length includes the two clamps. You can connect the fan, the filter and the air outlet without buying anything else. It is the handiest way to close a ventilation circuit in one go.

• Combiduct or Aluduct, which one suits me?

  If you want maximum performance and durability and your run is straight, go for the double-layer Aluduct. If what you need is flexibility and a good price for a run with bends or a temporary setup, the Combiduct is more than up to the job. In both cases, the fewer tight bends you make, the more real airflow you will keep.

• Can I adjust it to the length I need?

  Yes, it is extendable and can be cut up to a usable length of 3 m. That said, only stretch it as far as you need: leaving it compressed like an accordion increases the pressure loss. Getting the length right improves your fan's performance.

• How do I prevent odour leaks at the joints?

  Tighten the clamp firmly over the mouth of the unit; that is the point where odours usually escape. Also protect the bending points with a duct protector if the duct tends to get pinched. With those two details the circuit stays sealed and stable.

• Who does this duct suit best?

  Its value for money is aimed at home setups and grow tents. It is especially convenient if you set up and take down your installation often, because it is very flexible and light. As it weighs little, it puts less strain on the tent's straps and hooks.
