Due to the rising costs of energy, SIYI big ceiling fans are often used to supplement HVAC systems as they provide a stronger cooling effect while helping to maintain a constant temperature and humidity. With power of 1.5kw, SIYI 24ft large fan can provide natural wind to 1300㎡ area. SIYI industrial large fans are not only energy saving, but also make people feel comfort, so it is really the best choice for large space. SIYI is a professional industrial ceiling fans company in China and industrial ceiling fan prices are competitiveDetailed SpecificationsModelSYD61Fan Diameter6.1M (20FT)Airfoil MaterialAluminum AlloyAirfoil FinishesPlastic SprayingWeight145KGHeight1.1M (3.3FT)Number of Airfoils6PCSController includedYesVoltage220V/380V/415VFrequency50HZ/60HZRPM(min/max)20/50RPMPower1.5KWCoverage area1100M²Warranty3YearsProtectionIP55Blades The blade is the core technique of the fan. We use simulation software ANSYS to make the blades with most reasonable transversal surface and inner limiting plate. The limiting plate is also very important. If it is not settled in the right place, it will make the blades shake or even broken. SIYI fans have six or eight PCS of blades and winglets to ensure maximum airflow and efficiency. Unique designed winglets at the airfoil tips greatly eliminate wind noise. The blades is made of aluminum alloy with plastic spraying finish, so it can resist corrosion and dust very well. SIYI company invites Germany designer to analyze and test the blades. We found the ratio between length and weight must be settled within 410-425 to ensure the blades will not be broken forever. So it is unscientific to make the blades too thick or too wide.  Packing One fan is packed into two wooden cases. 1)20*30*230CM 2)30*40*90CM
