HVLS (High Volume Low Speed) industrial fan is a large-sized ceiling fan used in industrial spaces such as factories, warehouses, and other commercial buildings. 
HVLS industrial fan range from 7 to 24 feet in diameter, and their primary function is to provide air movement to create a more comfortable and healthier environment for workers. 
HVLS industrial fans rotate slowly, between 30 to 100 revolutions per minute (RPM), requiring less energy compared to traditional aircon or regular fans. 
They move a larger amount of air compared to standard high-speed fans, making them ideal for summer climate conditions. 
The industrial fan blades' size and shape are specially designed to move large volumes of air, providing a constant airflow, creating a cool breeze all around the area, and reducing indoor temperatures by 2 to 4 degrees. 
The HVLS industrial fans are energy-efficient, cost-effective and help to maintain a constant airflow quality, which can reduce the risk of heat exhaustion.
