Unlike residential ceiling fans that are typically 36 to 56 inches in diameter, SIYI industrial HVLS fans have very large diameters that start from12 feet to 24 feet. SIYI silent big size ceiling fans move very slowly unlike standard fans which operate at high speed. With large diameters and low rotating speed, SIYI largest industrial 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.Detailed SpecificationsModelSYD73Fan Diameter7.3M (24FT)Airfoil MaterialAluminum AlloyAirfoil FinishesFluorocarbon CoatingWeight155KGHeight1.1M (3.3FT)Number of Airfoils6PCSController includedYesVoltage220V/380V/415VFrequency50HZ/60HZRPM(min/max)20/50RPMPower1.5KWCoverage area1300M²Warranty3YearsProtectionIP55Motor After repeatedly tests, SIYI long blade electric giant fans adopt Germany NORD motor to ensure the low noise, efficient, reliable and durable operation.
