Greenhouse Shutter Exhaust Fan
Rugged, reliable exhaust fans
Provide reliable ventilation for your greenhouse with this exhaust fan. The fan motor is totally enclosed for protection from humidity. The galvanized shutter has felt-edged aluminum vanes that blow open from the fan draft and close when the fan is off. Steel wire safety grill surrounds the fan blade. The motor is 115-120 volts.
SELECT Cord or No Cord:
Cord: Prewired 9 ft. power cord with a 3-prong grounded plug included.
No Cord: No power cord or plug - for hard wiring into your system. (For your protection, all electrical connections must be made by a qualified electrical contractor.)
Airflow quantifies the amount of air a fan delivers and is measured in CFM = cubic feet per minute. The higher the CFM, the more effective the fan, and the more air it moves. (See Charley's Tip PDF below for how to select fan and shutter size for your greenhouse.)
* For automatic operation, order a Greenhouse Thermostat separately. (E3124-FAN Corded or E3124-HW Hard-Wire.)
* To enable seasonal adjustments, order a Fan Speed Control separately. (E3137 Corded or E3131 Hard-Wire.)
Note: Rough opening should be square and 1/2" larger than fan size. (Exception: 10" corded exhaust fan has a 12" shutter, so rough opening is 12-1/2" square.)
