Greenhouse Ventilation Package
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.

Add a Variable Speed Controller!
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.

Kit is well made and easy to install. Had to cut a bit more out of greenhouse sheeting. Wiring is very easy to do if you know electrical. I had a bad motor for intake... returned and another one showed up quickly. Thank you.
I purchased the commercial ventilation package to automatically ventilate my newly constructed home hoop house. The quality of the components is excellent and easily controlled with the temperature controller. The installation and wiring instructions for both the vents and fan were very clear.
The fan and louvers are high quality and work very well. There should be more instructional videos. Wiring the motor was difficult as there is very little room to make your connections.
Was very pleased with the product and the company.
Simple to install for any DIY projects.. As stated Electrical Schematics are a lil technical for someone without Professional Electrical knowledge.. Works great! Plenty of air flow for exhausting hot and humid air fast...
The shipping was expensive but well worth it. They did an excellent job of crating the fan and shutter which arrived quickly and in perfect condition. Easy installation and are working perfectly. My wife is very happy. used the size chart and they provide a good breeze when operating.
Once I figured out the wiring, this works just as I expected. For a smaller greenhouse, (8x16) it maintains the temperature well.
Very good system does exactly what its made for. Seems to be of very good quality. I built extra support for the fan because it seemed heavy to me but it was not needed, once it was installed it was very solid and well balanced. The fan is very quiet and has no vibration at all. I am an industrial electrician so wiring was no problem but can see where it would be tricky for a residential electrician or homeowner HINT ( ON the shutter motor the hot wire connects to line 1 the neutral connects to line 2 ) The instructions for the fan and thermostats were very clear and shouldn't be a problem for anyone with basic understanding of electricity. gave this a 4 because nothing ever gets a 5 but I couldn't have asked for a better exhaust system.
This is overall a good fan and shutters kit the only down side is there are really no wiring instructions so you have to know a little about wiring to get it all up and working.
package works flawless and quality parts.
