Features:1. High air volume and high wind pressure2. Compared with the traditional AC fan, the intersecting surface of the airfoil is relatively stable, the angle difference is small, the blade thickness is thicker, and the operation is more stable.3. The air volume under the same caliber is larger, which breaks through the limitation of the frequency of the traditional AC fan and greatly increases the fan running speed.4. Stepless speed regulation, can provide 0-10V voltage speed regulation and PMW signal transmission5. Compared with the AC pipe fan, the power is lower at the same speed and the energy consumption is lower, thus achieving the effect of power saving6. Widely used in conference rooms, high-end office buildings, public places, hotels, houses, hospitals, gyms, etc.Specification:Condition: 100% Brand newItem Type: EC Motor Ventilation Exhaust FanPipe Diameter 8in/200mmModelVoltageCurrentPowerSpeedAir VolumeWind pressureVAmpsWRPMCFMPa8in220-240111035007604858in100-12021103500760485Optional Style: 110V, 220VPackage List:1 x Fan1 x Governor(concealed installation)4 x Expansion Screw4 x Screw1 x Connecting Cable
