Patterson 14" high-velocity fan
The smallest full-size Patterson high-velocity fan. It moves 2,600 CFM in a tight column out to about 60 ft, enough to keep air turning over in a single flower room, a veg room or a run of benches without blasting the plants closest to it.

Choose the motor for your power supply
Three motor options on the same fan. The size sets the airflow; the motor sets the power supply and how speed is controlled.
| SKU | Motor | Voltage | HP | Rated amps | Best for |
|---|---|---|---|---|---|
| H14A | Single phase, corded (12 ft cord) | 115V / 208–230V, 1-phase | 1/4 | 2.8 / 1.4 A | Plug-in rooms on standard outlets |
| H14B | Three phase, hard-wired | 208–230V / 460V, 3-phase | 1/4 | 1.5–1.4 / 0.75 A | Rooms wired for commercial three-phase |
| H14B-INV | Inverter-duty three phase, for VFD speed control | 230V / 460V, 3-phase | 1/2 | — | Banks of fans slowed or sped up together from one 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.

Where the 14" High-Velocity fan works best
- Single flower or veg rooms up to roughly 1,800 ft² per fan
- Rack-level airflow in multi-tier rooms with the RM 14 rack mount
- Mother rooms, clone rooms and drying rooms where a 22" or larger fan would be overkill
Common questions
Which motor do I need?
If the room has standard single-phase outlets, the A model plugs in on its 12 ft cord. If the room is wired for three-phase commercial power, the B model is hard-wired. Choose the INV model if you want to control the speed of several fans together from a variable frequency drive.
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.
Is there a white EC version?
Yes for the 14", 18" and 22" sizes. Patterson EC variable-speed fans use an auto-adapting 115–277V motor with speed control from 300 to 1,800 RPM.
