Metal Reduction Coupling – Reducing Connector for the Union of Different Extraction Ducts

Frequently asked questions

• What is the metal reducer coupling and what is it used for?

  It's a reducing connector that joins two ducts of different diameters into a single connection. It lets you increase or decrease the duct size along your extraction system's run without having to change the entire installation.

• How do I know which reducer I need?

  First you need to know the measurements of the two sides you want to join: the diameter of the inlet duct and the outlet duct. With those two figures you can choose the right coupling and the connection will fit without any issues.

• Does it affect the airflow in the setup?

  Yes, and that's one of its advantages. By changing the duct diameter you can control the amount of air passing through the connection, adjusting the flow to what each section of your system needs.

• Does it need any special maintenance?

  No. It's made from a rust-resistant material, so you won't need to worry about ongoing maintenance. Once installed, it stays in place without you having to keep an eye on it.

• What sizes are available?

  There's a wide range, from 125-110 mm to 400-315 mm, precisely because duct diameters vary a lot from one setup to another. Check which combination fits your ducts and choose the right model.

• How is the coupling secured once it's in place?

  It's placed between the two ducts you want to splice together and the joint is secured so it stays firm and free of gaps. The important thing is that both ends fit snugly, so no air escapes through the connection.
