HVLS Fan Guides

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...

Industrial Fan Comparison Choosing between an HVLS ceiling fan and an industrial standing fan is not simply a matter of fan size or motor power. The two fan types are designed to solve different airflow problems. An HVLS...

HVLS Motor Selection Guide Most HVLS fans use one of two drive systems: a direct-drive motor or a geared motor system. Direct-drive designs connect the motor directly to the fan hub, while gear-drive systems use a gearbox to...

HVLS FAN FUNDAMENTALS HVLS stands for High Volume, Low Speed. An HVLS fan uses a large blade diameter and relatively low rotational speed to move a substantial volume of air across a broad area. Instead of creating a...
