Third photo is to show VFD.

Older-style Triac-controlled variable speed fans would get less efficient the slower they ran due to regulating the voltage, thereby making the CFM/Watt (or (m3/hour)/W) worse. The V-Fan motor is not only VFD-driven, meaning the frequency (hertz) to the motor is driven, but it's also a PMAC motor, yielding greater efficiency than induction VFD-driven motors.

V-Fan is direct drive - so no belts to maintain or bearings to grease The VFD gives you the control you need to provide the ideal environment
