Automatically cool your greenhouse

Powerful, forced air ventilation automatically cools your greenhouse when needed. The fan is matched with a specific size of shutters to provide you the optimum airflow. The weather-proof thermostat allows you to set the operating temperature to turn your system on and off automatically. A fan speed control enables seasonal adjustments to airflow. Shutter motors hold shutters wide open for maximum airflow.

Includes shutter-mounted exhaust fan, shutters with shutter motors, thermostat, and fan speed control. Standard aluminum finish.

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.) Use Fan Size to choose your system.
