FAN STRUCTURE
The centrifugal fan VKV/VKV EC (fig. 1) consists of the pan 1 connected
through a net to the base with the fixed electric motor and impeller on it.
The VKV EC fan is equipped with EC motor.
The protecting housing 2 is also fixed to the pan.
The cover 3 that protects the electric motor against weather factors is
fixed to the base.
The terminal box is fixed to the upper casing part for connection of the fan to
single- or three-phase power mains and placement of the operating capacitor.
