How to Choose the Best HVLS Fan for Your Facility

The warranty on an HVLS fan varies by manufacturer and ranges from a few years to decades. Some manufacturers reduce the warranty in half if another service provider installs their fan. Other manufacturers offer a full warranty regardless of who installs it. MacroAir offers mechanical warranties up to 15 years and electrical warranties up to 10 years, regardless of who installs it.

Winglets negatively impact the performance of an HVLS fan by increasing the amount of energy the fan uses and making the fan wear out faster. The small, curved caps added to the edge of some HVLS fan blades have sparked much debate. Some companies add winglets to capture and move more air, but it actually hinders a fan’s performance.

A trained HVLS fan specialist should help you decide where to place an HVLS fan based on the size of the fan and the layout of your space. Correct placement on HVLS fans with variable frequency drives (VFDs) is crucial for your HVLS fan to run optimally.

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.
