HVLS Fans

4Front's High Volume Low Speed (HVLS) fan series is designed to provide facilities with an energy-efficient and cost-effective cooling and heating solution. High Volume Low Speed fans move large volumes of air at low speeds over very large areas. The fan blades produce a massive column of air that flows down to the floor and outward in all directions, creating a deep “horizontal floor jet” that ultimately circulates air up vertically and gets drawn back through the top of the fan.

The result is more consistent temperature control, improved airflow / circulation and improved energy efficiency. In cooler months, the HVLS fan operates in reverse, circulating hot air trapped at ceiling level and creating a warmer and consistent mix of air throughout the facility (referred to as "destratification").
