Super reliable, high quality and hassle-free equipment No wiring up is necessary due to plug and play nature of the products Handily include power lead and hanging attachments Covered by a 2 year manufacturer’s warranty How Do EC Fans Work? Fans that employ older tech (AC) use the same power regardless of the speed setting selected on a traditional resistance based controller. With EC Fans – including all of those in the Mammoth S-Max Pro range – if you don’t need to run one at full pelt, you can reduce the speed and consequentially reduce the power consumed via a suitable controller. This perk of EC equipment means that a 10% speed reduction roughly equates to 10% less power used, a 20% speed reduction roughly equates to 20% less power used, and so on. Massive savings are up for grabs then, to a point where a fan will soon pay for itself! The Advantages Of Acoustic Fans Sound – or the lack of it – will be what initially grabs your attention when running a Mammoth S-Max Pro EC Fan! These workhorses can move an immense amount of air without making any real noise at all thanks to the streamline design and noise-dampening foam inside the metal chassis.
