Mounted high on a shop or garage wall, the ES Shutter Fan pulls hot, stale air out of the building, and its aluminum shutter closes when the fan stops. Corded models plug straight into a 115V outlet.
Size it by its static-pressure rating: J&D lists 0.10" SP airflow from 748 CFM for the 12" to 5,801 CFM for the 30", and the shutter side should sit at least 7' above the ground.
The housing is heavy-duty 18-gauge galvanized steel and the motor is fully enclosed with a sealed capacitor, so the fan suits greenhouses, wash areas and other humid interiors.
It is an indoor fan, not outdoor rated, so the motor should stay on the inside of the wall. Add a J&D weather hood to protect the shutter side from wind and rain.
The high-efficiency aluminum shutter has fortifying ribs and a tie bar that reduces flapping and opening on windy days, so the opening stays closed when the fan is off.
On the motor side, a coated steel guard meets OSHA 1910.212(a)(5) and wipes clean, and a balanced three-blade aluminum prop on a coated steel hub keeps it running smoothly.

No. For outdoor exposure choose J&D's Indoor/Outdoor ES Shutter Fan, which has a UL507 outdoor-rated motor.
Not for the corded models (part numbers ending in C), which plug into 115V. The uncorded single-phase and three-phase models are hardwired.
A rough opening 1/2" larger than the fan: 12-1/2" square for the 12" up to 30-1/2" square for the 30".
Use the static-pressure figures: at 0.10" SP J&D rates the 12" at 748 CFM, the 20" 1/3 HP at 2,697 CFM, the 24" at 3,849 CFM and the 30" at 5,801 CFM.
Some models are speed-control compatible with a separate variable speed control (not included). The per-model table in the Specifications tab shows which.
No. J&D does not supply wall fasteners; use fasteners and washers suited to your structure.
