(OP)
I noticed an inverter pack on some very modern large air handling plant, presumably to control speed. Is there any advantage in using an inverter for such speed control requirements?

RE: INVERTER

Adjusting the motor speed to control air flow can be much more efficient than the traditional method of using a modulating damper.  With the damper, you are using up a lot of energy in the pressure drop across the damper.  This is eliminated with an adjustable speed motor.

These are very common for commercial air handling units.
