Powerfoil® X4
Designed with the size, power and efficiency to tackle oppressive temperatures or stagnant air head on. Powerfoil X4 is perfect for spaces that need strong, durable and unmatched airflow.
Product Highlights
Powerfoil X4 is the perfect choice for facilities that require maximum airflow and long-term reliability. Its powerful, maintenance-free motor moves more air than any other HVLS fan, providing superior performance and efficiency.
Powerfoil X4 is available in diameters ranging from 4.3m to 9.1m. With the ability to move up to 118 cubic meters of air per second, Powerfoil X4 provides exceptional performance and efficiency. The fan’s airfoils feature an aerodynamic design, cuffed winglets, and AirFences™, which reduce choppy wind and noise, keeping comfort consistent throughout your facility.
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.
