Some HVLS Fans Have 3 Blades, Some Have 5, Some Have 6, And Some Have 10. What's The Difference?

The differences are the amount of airflow the fan can produce, the energy it uses, and how it affects your building’s infrastructure. Different manufacturers have varying beliefs on how many blades are best for specific situations. However, with today's technology at play, fans with fewer blades move an extreme amount of air and are more energy efficient because of the lighter weight.
