New for 2017, the Hacker StreamFan 110mm EDF 850 combines a specially-designed Hacker brushless motor with an EJets Jetfan 110 PRO 11 blade impeller to deliver a tremendously powerful and reliable EDF system. The new Hacker E50 motors are specially designed for use in EDF units. Careful attention has been paid to reduce weight and ensure cool operation.
The impellers and motor units are completely assembled and finely balanced for unbelievably smooth operation. The 11 blade impeller unit has a truly distinctive sound and amazing power delivery.
850kv works well on 10S. Use this fan for a lower voltage setup — save weight by using fewer cells.
