5-blade Polyethylene High Volume, Low Speed (HVLS) fans blend layers of air together (destratify) to equalize overall temperature. This prevents product spoilage in warehouses with high storage areas where temperature is much warmer. Improve airflow, save on energy and reduce perceived temperature by 7-11 degrees. Moisture levels are also reduced, keeping your floors drier and safer. In addition, fans set in reverse during the winter months bring cool air up and warm air down to floor level. Overall, HVLS fans serve as a year-long tool to save on energy and increased employee comfort levels. Click to see how they work.
