Our 100mm extractor fans & ducting collection includes everyday ventilation essentials for bathrooms, toilets, utility rooms and small kitchens. Designed around the standard 100mm size, these extractor fans, ducting components and accessories help remove moisture, odours and stale air where space is limited. Whether you are replacing an existing unit or fitting out a new room, this range keeps things straightforward and reliable.

This collection is suited to trade electricians, installers and capable DIYers looking for 100mm ventilation solutions that are easy to specify and fit. You will find axial extractor fans alongside matching ducting, vents and fixing accessories, all sized to work with common 100mm systems found in domestic properties across the UK.

100mm extractor fans are commonly used in bathrooms, en suites, cloakrooms and small kitchens where localised extraction is required. Combined with the right ducting, they help manage condensation, reduce mould risk and improve overall air quality. They are also suitable for utility rooms, cupboards with appliances and other compact spaces needing basic airflow.

When choosing a 100mm extractor fan or ducting, consider where the fan will be fitted and the length of duct run required. Straight runs are simpler, while longer or angled routes may need additional ducting sections or bends. Also think about whether you are replacing like for like or installing from new, as existing cut-outs and connections can influence the best option.

All items in this range are sized to standard 100mm systems, helping ensure straightforward compatibility between fans, ducting and external vents. This makes it easier to build a complete ventilation setup without mixing sizes. Each product is listed individually, allowing you to choose only the components you need for the job in hand.
