A HVLS (High Volume Low Speed) fan is a very large ceiling or pole mounted fan with blades from 7-24 feet long. A HVLS fan moves large volumnes of air because of it's blade length and design.
HVLS fansbreak up the moist aire and accelerate evaporation to produce a cooling effect. The Serco ATEC's airfoil style blade design produces a massive, cylindrical column of air that flows down to the floor and outward in all directions, creating a horizontal floor jet that consistently circulates air in large spaces. This 'horizontal floor jet' pushes air a greater distance before it is pulled back vertically toward the blades. The greater the down flow, the greater the air circulation and resulting benefits.
In the colder months, fans can be run in reverse to circulate the hot air trapped at ceiling level known as 'destratification', pushing the warm air back down to the lower levels, and reduces heat loss through the ceiling.
