Every greenhouse needs airflow to regulate temperature and humidity levels. A Greenhouse Ventilation Kit from Greenhouse Megastore is an all-in-one package to install venting for any enclosed space. It includes one or two commercial shutter greenhouse fans with a thermostat and motorized aluminum shutter(s). By hardwiring the J&D single-stage thermostat to an electrical power source, you can set the shutter and fan to turn on and off automatically based on the temperature. You can add an optional variable speed controller for more precision.
We offer nine ventilation systems with different greenhouse fans and shutters based on the amount of space you need to circulate air. See the CFM ratings below for each system and use our guide to determine how much airflow is required in a space. Greenhouse ventilation systems are also ideal for workshops, garages, warehouses and other areas that need temperature control and airflow. We have free shipping in the contiguous U.S. and provide full sales and technical support.
Save money by ordering this complete ventilation package. This package consists of our Commercial Shutter Fan, Aluminum Shutter(s), and a J&D Single Stage Thermostat. All items must be hardwired to an existing power source.

How Do I Size My Fans and Shutters System?

1. The first thing that you need to determine is the amount of air required. This is stated in CFM (Cubic Feet of Air per Minute).
2. Use the following formula to determine the CFM required for your greenhouse:
CFM = Length x Width x Height
Example: Greenhouse 12' wide x 24' long x 12' high requires 3456 CFM (12 x 24 x 12 = 3456)
3. Reference the above table. Select the appropriate combination of fan(s) to achieve the necessary CFM rating. Be sure to match the total CFM output for your exhaust fan(s) to the CFM ratings for your Inlet Shutters.
