Four- or six-pole asynchronous motor with external rotor and double intake centrifugal impeller with forward curved blades.The motor is installed on specially designed vibration-damping mounts to absorb vibration and noise.Equipped with ball bearings for longer service life.Integrated thermal protection with automatic restart.Dynamically balanced turbine.


Smooth speed control with an external thyristor controller or step speed control with an external auto transformer (both available upon separate order).


G – temperature and speed controller with external temperature sensor fixed on 4 m cable.GI – temperature and speed controller with a sensor built into the fan casing.
G and GI options are used for automatic speed control depending on indoor temperature. The best ventilation solution for the premises requiring permanent temperature control as greenhouses, orangeries, etc.
W – the fan is equipped with a power cord and a socket or plug (W1).max – high-powered motor.
