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.

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.
Great system, moves a lot of air through my greenhouse and the thermostat is very accurate. Only problem I'm having is the louvers on the fan don't completely close when the system shuts down, they stay cracked open about a 1/4 inch maybe more, just enough for insects to get through. I built a small frame around it covered with insect screen and chicken wire now it's okay but it would be nice if it closed all the way. Other that the cracked shutters the ventilation kit works great and I already recommended it to two other friends who have purchased, installed and now love it as well.
