HVLS Fan Guides

Delivery Availability Project Support Installation Coordination North Carolina Project Guide HVLS fans are available for warehouses, manufacturing facilities, workshops, agricultural buildings and commercial high-ceiling spaces in North Carolina. The correct model depends on ceiling height, available voltage, structural...

Airflow Testing Visual Methods Site Conditions An HVLS fan demonstration shows how a large ceiling fan moves air through an actual space. Air velocity measurements, smoke visualization, ribbon tests and installation videos can reveal downward airflow, floor-level spreading...

HVLS Guide Seasonal Operation HVLS fan reverse operation is not a universal winter setting. Some reversible models use low-speed reverse rotation to create upward airflow and reduce noticeable drafts below the fan. Other HVLS designs may provide more...

Preventive Maintenance Inspection & Service Guide Routine HVLS fan maintenance includes inspecting mounting hardware, safety cables, airfoils, hub components, the motor or gearbox, controllers, wiring and surrounding clearances. Facility teams should also watch for unusual noise, excessive vibration,...

HVLS Fan Engineering Guide HVLS fan tip speed is the linear speed of the outer edge of the blade as the fan rotates. It is determined by fan diameter and rotational speed . Because HVLS fans have large...

Wide, low-speed airflow can support comfort and more consistent air distribution across large occupied spaces. Wide-Area Airflow Benefits HVLS fans improve comfort in large spaces by using large-diameter airfoils that rotate at relatively low speeds to move a...
