Patterson high-velocity fans push a tight column of air across the canopy, through the rows and under the racks, so a grow room holds even temperature and humidity instead of pockets of still, wet air. Hydro Supply Co. carries the indoor-grow line: high-velocity fans from 10" to 30", EC variable-speed fans, inverter-duty fans with VFDs, and the mounts to hang them where the air is needed.
Every high-velocity fan ships with the standard yoke mount, a galvanized aluminum propeller, OSHA-compliant spiral-wound steel guards and a totally enclosed, air-over motor rated for continuous duty. Size sets the reach; the motor sets the power supply and speed control.

115V or 208–230V single phase with a 12 ft cord. 1/4 HP on the 14", 1/2 HP on the 18" and 22". Plug in and run.
208–230V or 460V three phase for rooms wired for commercial power. 1/4 HP on the 14", 1/2 HP on the 18" and 22".
230/460V three-phase motors built to run from a variable frequency drive, so a whole bank of fans can be slowed or sped up together. 1/2 HP on 14"–22", 1 HP on 26" and 30".

The same 14", 18" and 22" high-velocity fans with an electronically commutated (EC) motor and a white finish. Speed runs anywhere from 300 to 1,800 RPM, so you can run gentle air over clones and young plants and turn it up as the canopy fills in.

A compact 115V fan with a totally enclosed 2-speed motor and a 40 ft air throw. Sized for trim and processing stations, drying-room corners and short racks where a full-size fan would be too much.
The yoke ships with every fan. Rack mounts hang a fan off racking or shelving to clear the canopy; the beam clamp grips a structural beam or truss without drilling.

Arm lengths matched to the fan size.

Clamps 14"–30" fans to beams and trusses.
1 ft mounting pole for dropping a fan below a beam or ceiling mount.
All mounting options (PDF) →EC fans take the Symax controller. Inverter-duty (INV) fans run from a variable frequency drive, sized to the total horsepower on the drive and to the facility's input power.
