All components of this system are adapted to the humid greenhouse environment. Parts are made of aluminum, stainless steel, and PVC; and all steel parts are either enameled or vinyl coated. The variable speed exhaust fan is mounted on a rustproof PVC shutter. The motorized PVC shutter is neatly assembled and closes tighter than other shutters. The shutter motor is in an aluminum housing preinstalled on the shutter frame. The thermostat and variable fan speed control are water-resistant when installed according to directions. (System thermostat may vary from pictured unit, as available. Thermostats E3124-HW and E3127-HW have the same specs. See E3127 product page for wiring diagrams PDF.)
This is a hard-wired 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.)
|Fan Size||# of
|8ft x 16ft||12 inch||1||22 inch||760|
|10ft x 12ft||12 inch||2||16 inch||760|
|10ft x 20ft||16 inch||2||22 inch||1250|
|14ft x 20ft||20 inch||3||22 inch||3000|
Rough opening should be square and 1/2" to 5/8" larger than fan or shutter size.
