What is SIYI big size ceiling blower fans?

SIYI fan is a type of mechanical fan used in commercial and industrial settings. Unlike residential ceiling fans that are typically 36 to 52 inches in diameter, SIYI fans have very large diameters that start at 12 feet and go up to 24 feet. SIYI fans move very slowly unlike standard fans which operate at high speed. With large diameters and low rotating speed, SIYI fans can move large amounts of air, so it is named “high volume, low speed” (HVLS) fan.

HVLS fans are widely applied in livestock barns, warehouses, distribution centers, shopping malls, skating rinks health clubs and so on. Due to the rising costs of energy, HVLS fans are often used to supplement HVAC systems as they provide a stronger cooling effect while helping to maintain a constant temperature and humidity.

How to work?

The unique airfoil blades on the SIYI fan produce a massive, cylindrical column of air that flows down to the floor and outward in all directions.  This horizontal floor jet pushes air a greater distance before it begins to move vertically and is drawn back through the fan.   The greater the down flow, the greater the air circulation will be.
