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.
Some HVLS fans are designed to fit into smaller spaces (like the Hunter XP, which is available from 7’ to 14’), and some are much larger (like the Hunter Titan, which is available at a whopping 24’, or roughly 3.4 Shaqs). Either way, HVLS ceiling fans are larger, spin slower, and move WAY more air than the average residential fan.
