The concept of using overhead fans to create cooling air flows has been around for a long time and everybody is familiar with the humble ceiling fan.
High Volume Low Speed or HVLS fans have taken the ceiling fan idea and scaled it up to produce highly efficient large diameter fans for cooling big spaces and often, big crowds.
These functionally elegant fans in sizes up to 7.2 meters across spin slowly and silently but move huge volumes of air at summer breeze speeds.
The result is improved comfort in large building spaces with very low running costs. Air volumes of up to 9,800 cubic meters per minute are achieved for as little as 35 cents per hour.
HVLS fans come into their own where refrigerated air conditioning is simply not a viable option due to high equipment and ongoing running costs.
Typical applications include indoor sporting facilities, schools, churches, retail stores, offices and entertainment venues.
