Powerfoil® X4
Designed with the size, power and efficiency to tackle oppressive temperatures or stagnant air head on. Powerfoil X4 is perfect for school halls, gyms and large open areas.
Product Highlights
For schools in need of maximum airflow and long-term reliability, Powerfoil X4 is the ultimate choice. Its maintenance-free motor moves more air than any other HVLS fan and comes with an unprecedented 15-year warranty, ensuring peace of mind for years to come.
Available in diameters ranging from 4.3m to 9.1m, Powerfoil X4 creates the most airflow of any big fan on the market, moving up to 118 cubic meters of air per second. The airfoils’ aerodynamic design, cuffed winglets, and AirFences™ minimize choppy wind and noise, providing powerful yet gentle breezes that remain consistent throughout your space.
Energy Usage
With Powerfoil X4’s energy-efficient motor, this fan uses minimal energy to deliver powerful airflow, creating comfortable conditions far more efficiently than air conditioning. In winter, the fan equalizes temperatures from floor to ceiling, making heaters more efficient.
By reducing existing HVAC costs by up to 30%, Powerfoil X4 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.
