Common Query Answered: Connecting Fans to Ducting

A simple guide to help you to connect ducting to fans.

Whether you’re setting up a ductwork system for a workshop, commercial setting, or a home project, connecting ducting to a fan correctly is essential for optimal airflow and system efficiency.

A secure connection helps to reduce noise, prevent leaks, and ensures your ventilation setup performs exactly as it should.

How do I connect my ductwork to my fan?

Different fans require different connections, see below some examples of which fans require which type of connection.

Fans such as the inline tube fans and inline mixed flow fans do not require any additional parts to connect into spiral ducting pipes. These fans have a small end spigot to allow them to fit directly inside spiral ducting.

Fans such as case mounted axial fans and contra rotating fans generally have an outer flange which you would need a matching flange to enable you to connect them to spiral ducting. See the options for connecting them to spiral below.

To connect your fan to your ductwork you could either use a mounting flange or alternatively, a flat bar flange with a top hat spigot.
