Big Fans – HVLS Fans Ask An Expert Request a Quote Request Service Or give us a call: 1-888-606-9415 HVLS (High Volume Low Speed) fans are an effective means of improving worker comfort while reducing or eliminating HVAC costs. Today’s technologically advanced and engineered HVLS fans, also known as Industrial Ceiling Fans or Warehouse Fans, promote beneficial air circulation within an enclosure. The slow speed airflow created by the big fans provides tangible benefits in all seasons and climates. Warm air rises. During the winter heating season, the fans are operated in reverse to gently force warm air down from the ceiling to floor level without the effects of wind chill, thus improving temperature uniformity within the building and reducing heating costs. In warm months, the fans create a gentle breeze (2-3 mph). The breeze creates a 7 to 11 degree decrease in perceived temperature, improving occupant comfort and reducing the burden on AC systems in climate controlled environments. In addition to improving occupant comfort, the air currents created by the industrial ceiling fans promote evaporation, minimizing condensation and moisture build-up on floors, humidity sensitive products, packaging and other surfaces. This in-turn can reduce moisture related slip hazards in humid environments and contribute to maintaining fresh and dry product in food handling environments. The fans have earned the nickname ‘big fans’ and ‘big ass fans’ due to their large size. Models are available with blade diameters from 8 to 24 feet. Despite the large size, the units install quickly and provide reliable, low cost operation. Typical operating costs for the largest fan sizes are less than $3 per day, based on 24hr continuous operation. HVLS Fans Save Energy and Money The energy saving and environmental benefits of industrial fans are widely recognized. LEED certification credits are available to architects and builders who incorporate industrial fans into their building designs.
