High-velocity low speed (HVLS) fans are large ceiling fans designed to move a significant amount of air at low speeds. These fans are commonly used in industrial and commercial settings to improve air circulation and increase energy efficiency. They are also used in large public spaces like mosques, office buildings, and schools.

HVLS fans are ideal for such spaces because they can help to reduce temperature stratification, which occurs when warm air rises and cold air sinks. By moving the air in a circular motion, these fans can help to equalize the temperature throughout the space, creating a more comfortable environment for occupants.

In addition to improving comfort, HVLS fans can also improve productivity in workplaces by reducing the heat stress on workers. By circulating air, these fans can help to evaporate sweat and cool the body, reducing the risk of heat exhaustion and other heat-related illnesses.
