Inverter-duty motor
We carry this size with the inverter-duty three-phase motor, built to run from a variable frequency drive so a whole row of fans can be slowed or sped up together.
| SKU | Motor | Voltage | HP | Rated amps | Best for |
|---|---|---|---|---|---|
| H30B-INV-W | Inverter-duty three phase, for VFD speed control | 230V / 460V, 3-phase | 1 | — | Greenhouses and large halls on a VFD |
Rated amps from Patterson's spec sheet. Rated amps for inverter-duty motors are not listed on Patterson's spec sheet; the VFD is sized to total fan horsepower.

Common questions
How is speed controlled on the INV model?
Inverter-duty fans run from a variable frequency drive (VFD). One drive can run a bank of fans; it is sized to the total horsepower on it and to the facility's input power. We carry E510 drives from 3 to 8 HP in 230V and 460V versions. See Patterson controls and VFDs.
How is it mounted?
Every fan ships with a yoke mount for walls, posts and ceilings. Rack mounts hang it from pallet racking or shelving to clear the canopy, and the beam clamp grips a structural beam or truss without drilling.
Can it run at lower speed?
Yes, through the VFD. Turning down the drive slows every fan on it, which lowers airspeed and noise when full speed isn't needed.
