High-volume, low-speed (HVLS) fans are an energy-efficient alternative to high-speed box fans, which are traditionally used for ventilating livestock barns.
Ideal places for HVLS fans include large areas that have high ceilings and few vertical structures that would block horizontal air flow, including:
- Open-stall livestock barns
- Barns with large open doors
HVLS fans keep livestock cool in the summer, and warm in the winter. Plus, HVLS fans use much less electricity than typical high-speed fans that move similar amounts of air. In addition to energy savings, you get drier floors, fewer flies and less noise.
Each HVLS fan installed (must be 16 ft. or larger in diameter) qualifies you for $750.
