Unlike high-volume, low-speed ceiling fans, Schaefer’s 72-inch BIGDOG® ventilator moves a lot of air at high speed for efficient and effective summer personnel cooling in shop and warehouse environments. With a variable speed motor, the BIGDOG can cool a 7,000-square-foot area. Also effective for moving heated air down from the ceiling for dramatic heat savings during cold winter months.
