Powerfoil® D

Designed with state-of-the-art technology, Powerfoil D packs a punch with its powerful yet silent airflow. It is the perfect choice for tackling oppressive temperatures and stagnant air in any space, no matter how large.

Product Highlights

Powerfoil D was designed to tackle oppressive temperatures and stagnant air in large spaces, whether indoor or outdoor. With an IP66 rating, it can withstand various environmental conditions. Unlike other gearless overhead fans, Powerfoil D can effectively deliver quiet comfort to large spaces. Its virtually silent motor and 15-year warranty guarantee reliability and performance for years to come.

Powerfoil D is available in diameters ranging from 4.3m to 7.3m, creating powerful airflow of up to 109 cubic meters per second. Its airfoils feature an aerodynamic design with cuffed winglets, minimizing wind turbulence and noise, ensuring consistent airflow throughout your space.

Energy Usage

With its energy-efficient motor, Powerfoil D uses minimal energy to deliver powerful airflow, creating comfortable conditions far more efficiently than air conditioning.

By reducing existing HVAC costs by up to 30%, Powerfoil D pays for itself in no time. And with an estimated annual operational cost of just $1,030 per year (about $2.82 per day), you can enjoy the benefits of this energy-efficient fan without breaking the bank.

In the event of severe impact damage, the Airfoil Restraint® System suspends the fan’s airfoils, preventing them from dislodging and potentially causing harm.

US made, local support

Our Powerfoil D was designed and built in our custom-made manufacturing facility in Lexington, Kentucky. Stocked locally for quick dispatch, with a Brisbane-based support team and national network of certified installers for a seamless experience.
