Economy Vent System
Prewired Economy Vent Systems
Low-cost, life-saving ventilation for your plants! Automatic fan reduces excessive heat on hot, sunny days. Set thermostat for maximum desired temperature and fan will turn on automatically to pull cooler air through the intake shutter. For additional summer cooling, provide shading for the roof and plenty of water for humidity control.
Systems include an exhaust fan with 9-ft. power cord, a prewired water-resistant thermostat, and an intake shutter. (System thermostat may vary from pictured unit, as available. Thermostats E3124-HW and E3127-HW have the same specs.)
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.)
| Fan Size | CFM |
Shutter Size |
| 10 inch | 460cfm | 16 inch |
| 12 inch | 750cfm | 20 inch |
| 16 inch | 1030cfm |
24 inch |
Rough opening for 10" and 12" exhaust fans is 12-1/2" square; 16" is 16-1/2" square. Shutter opening is 1/2" larger than shutter size.
* To enable seasonal adjustments, order Prewired (Corded) Fan Speed Control separately (E3139).
