NEW LOCAL HVLS FAN
Supplied by EverBreeze , these High Volume Low Speed ( HVLS ) fans are typically ceiling mounted . They turn at low speeds , producing continuous air columns that move gently to provide a natural evaporative cooling effect .
HVLS fans do not add or remove thermal energy to the air . Rather , they move large masses of air with very little energy consumption and enhance the processes of evaporation and destratification .
Product applications include :
• Factories , warehouses , and distribution centres
• Agricultural storage and food processing plants
• Breweries and bottling plants
• Public retail and leisure spaces
• Libraries and other academic environments
• Transport hubs
Unit range includes :
• Fan : Diameters range from 3.9m to 7.4m with 1 000 to 4 200 m ² coverage area respectively .
• Motor : IE3 premium efficiency 4-pole geared motor , IP55 rated and self-ventilated .
• Aerofoils : Anodised aluminium made from aircraft grade alloy .
