Twin Fans | Nuaire

Nuaire invented the twin fan over 40 years ago. Today, our expertise and experience remains unmatched in the ventilation sector.

Our range of market-leading twin fans are still the smallest, quietest and most energy-efficient, offering reliability in applications where 24/7 ventilation must be guaranteed.

We offer twin fans with duties from 0.02m3/s up to 6.2m3/s, with options for constant pressure and bifurcated models, as well as internal and external variants.

The Aire-Volve range offers the very latest in twin fan technology. With lower SFPs, lower noise and smaller case size than the competition, Aire-Volve’s patented damper arrangement means it can be installed at any angle.

How Twin Fans Work

Generally used for toilet extract, smaller twin fan units can be installed into ceiling voids whilst larger units can be situated in plant rooms. Nuaire’s twin fans utilise two fans to provide ventilation 24/7. Auto-changeover operation every 12 hours means that, in the event of one fan ever failing, the other will begin working to ensure that the required ventilation levels are maintained.

With two fans positioned together it allows for use as run and standby, and, with Nuaire’s control systems, the primary fan is changed over regularly to ensure component life is maximised. Nuaire’s ‘auto-changeover’ control is a true run-and-standby system so each fans assembly is run and proven every 12 hours.

Nuaire’s pedigree has been in high quality, reliable ventilation systems, with Twin Fans being a core product. We offer run-and-fail indicators as standard (Ecosmart models) to ensure client satisfaction and peace of mind.
