improve efficiency & reduce energy with HVLS oversized fans

better efficiency with HVLS oversized fans for large rooms and high ceilingsDid you know that productivity drops by 2% for every degree rise in temperature above 77ºF? In addition to that, you could be facing worker's compensation claims due to the increased risk of heat-related injuries at higher temperatures; for this reason, OSHA recommends solutions that address ventilation and airflow to control your facility's temperature. However, you'll want a fanning system that does more than push hot air around and drives up energy bills. HVLS oversized fans for large rooms and high ceilings provide better efficiency than the competition, so you can keep your facility cool while saving on energy costs.

HVLS oversized fans vs. air foil fans

What makes the HVLS oversized fans different from other air foil fans is the tubercle-style blades. Tubercles allow the fan to be both powerful and efficient with its unique blade design. The tubercles allow the air to pass across the blade with much less wind resistance, which makes the fans able to move more air at a slower speed with less blades, which saves on energy bills. The blade pitch of the oversized HVLS fans can also be adjusted from a standard 8 degree pitch to a full 21 degree pitch. The fans move more air with five blades than competitive models with ten blades. Because the fans can be run at a lower speed and because the blades have a lower surface area than other fans, the oversized HVLS fans are also quieter than air foil style fans. For even more energy savings, the fans can also be run in reverse for winter heating.

additional benefits of HVLS oversized fans

Many additional benefits of installing HVLS fans for large rooms and high ceilings include:

  • Quiet and efficient operation; the largest 24 ft fans consume less power than an average hairdryer
  • Extremely low maintenance; recommended inspection every 20,000 hours
  • Inexpensive operation; approximately 6 cents/hour for one fan at 0.75 kw
  • Provides floor-to-ceiling and wall-to-wall constant and even ambient temperature
  • Creates air curtains and non-disruptive air flows
  • Minimizes need for expensive duct work in new construction
  • Comfortable work environment increases productivity, decreases absenteeism, and reduces risk of injury
  • Extended equipment life because the equipment doesn't need to cycle as often or as long as other fans
  • Energy savings in both summer and winter
  • Tubercle blades allow fans to move more air with fewer blades and less noise
  • Protects equipment from damage due to humidity and condensation
  • Decreases or removes airborne pollutants
