Inline Fans

Inline Fans are most common in residential properties, often mounted in a roof space to extract air from a bathroom. The key feature of inline fans is that ducting is fitted either side of it, leaving the fan "in line"!

As they are so often in a residential space, quietness is key. Many of our inline fans are almost silent! The noise rating can be seen on each product page, along with all the other technical data that might be required.


Our other fan collections include:

Plate Fans - Both for residential and commercial uses

Case Fans - For industrial air movement

Fan Connections, Mounts and Accessories - Not typically needed with inline ducting fans
