All VIRON® centrifugal fans are fabricated, assembled and tested in our two manufacturing locations. The testing begins with the fan wheels which are dynamically balanced. This electronic All VIRON® centrifugal fans have been tested in accordance to balancing guarantees smooth, vibration-free operation. After the wheel is balanced, it is assembled in the fan housing where it is tested at its operating speed. This second test uses the actual bearings, sheaves, belts, and motor. Here we fine tune the fan so that it operates as an efficient unit.
