Many people wonder how an HVLS fan differs from a regular, high-speed fan. The major difference between a high and low speed fan has to do with the way it affects the air. Small fans with high-velocity wind flows create air streams that are both turbulent and only have short-term, localized and temporary effects. By contrast, air flows from large diameter, slowly-rotating fans are known to move air around large spaces much more effectively, allowing a greater degree of environment and temperature control.

By pushing large volumes of air straight downwards, HVLS fans force the air to radiate outward in all directions once it hits the floor. The air moves laterally until it hits a wall, at which point these large volumes of air move upward, creating a convection effect that replaces humidity with dry air, which leads to a cooling effect during summer and redistributes warm air during the winter by moving hot air that has been trapped near the ceiling. By using an HVLS fan in your large industrial, commercial or agricultural space, you save money by reducing the cost of HVAC systems and their associated conditioning or heating functions.
