They go by many names. Warehouse fan. Industrial fan. Really, really, incredibly big fan. But those in the know refer to them by a simple set of initials: HVLS.
But the question remains, just what is an HVLS fan, and why is it necessary?
What does “HVLS” mean?
Let’s start with the initials. HVLS stands for “High-Volume, Low Speed,” and is used to describe the fact that these large fans move a high volume of air while spinning at a low rotational speed. More specifically, an HVLS fan is defined as any mechanical fan measuring more than seven feet in diameter. That means an HVLS fan must have a diameter that is about a wide as Shaquille O’Neal is tall. Typically, an HVLS fan spins at roughly 8mph, or between 71 and 200 rotations per minute, as compared to a residential fan that spins at approximately 230 rotations per minute.
Another key difference between HVLS fans and standard residential fans is a measurement called CFM, or Cubic Feet per Minute. This measurement indicates the volume of air moving through a fan every minute. While an average fan that you may have in your house can produce around 29,000 CFM with a 1-hp motor, an HVLS fan can produce about 140,000 CFM with the exact same 1-hp motor.
How Big Are HVLS Fans?
These large industrial fans measure anywhere from 7 to 24 feet. The Hunter XP HVLS fans are designed for tighter business spaces and are available from 7ft to 14ft. For bigger industrial spaces, the Hunter Titan HVLS fans are available at a whopping 24ft, or roughly 3.4 Shaqs. Either way, HVLS ceiling fans are larger, spin slower, and move WAY more air than the average residential fan.
