At Belkina-2 mine of Kazzinc SC the fan installation with a single stage axial fan VO-30VK manufactured together with FlaktWoods (Sweden), has passed acceptance testing and started operation.

 

Maximum static fan efficiency is 89%. The frequency drive provides stepless variable modes with rotating rotor. Reliability of operation is increased due to bearings vibration control and protection from unstable modes. The equivalent sound level in 100 m distance is 55 dB at rotation speed of 600 rpm.
