High Velocity, Low Speed Fans also known as HVLS fans operate by circulating large amounts of air by using air streams by pulling air from above the fan down. This effect greatly influences air velocity and humidity causing a room to feel cooler without needing to manually lower the temperature- helping companies save money on cooling costs.
HVLS fans are also a great resource during the winter as the fan prevents warm air from rising and collecting at the ceiling. Utilizing an HVLS mixes air layers creating a maintainable temperature throughout the room. While HVLS fans don’t directly lower or raise temperatures within a facility, its operation provides a comfortable environment without needing to increase the expense of heating and cooling.
HVLS fans are offered in two motor types: direct-drive and gear box. These two motors while similar have a few differences that may persuade a choice of one fan over the other. The main differences to consider are sound, speed, and price.
HVLS fans operate at a lower speed or RPMs (revelations per minute) than most traditional fans. Their large diameter, long blades and slow rotation gives the fan the ability to move large quantities of air at a more efficient rate, using less power decreasing energy costs.
