Industrial HVLS Fan Downflow Analysis 01:03

High-volume, low speed (HVLS) fans produce a massive, cylindrical column of air that flows down to the floor and outward in all directions which creates a horizontal floor jet that consistently circulates air in large spaces. Large industrial fans are available under the Kelley and Serco brands. More info at www.entrematic.us.
