Patterson Fans HVLS Ceiling Fan SFFCA73 For GYMs And Warehouse
A high-volume low-speed (HVLS) fan is a type of mechanical fan greater than 8 feet (2.5 m) in diameter. HVLS fans are generally ceiling fans although some are pole mounted and wall mounted. HVLS fans move slowly and distribute large amounts of air at low rotational speed– hence the name "high volume, low speed".
1. Lower noise level
2. Wider blades
3. Higher air volume
4. More energy efficient
5. Improved air circulation and distribution
