SIYI low energy big size fan is a type of super big fan used in large space and industrial settings. Unlike residential ceiling fans that are typically 36 to 56 inches in diameter, SIYI super big fan with large ass have very large diameters that start from12 feet to 24 feet. SIYI aluminum alloy blade ceiling fans move very slowly unlike standard fans which operate at high speed. With large diameters and low rotating speed, SIYI large shop fans are able to move mass amounts of air and then push the natural wind to super large area, so it is also named “high volume, low speed” HVLS fan.
