* Variable speed fans require separate variable speed control to adjust fan speed.
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 a ves20c, then another ves20c. The 2nd one ran much quieter and pushed less air. Since some time had elapsed, I presumed the first fan was a 24in not a 20. So when I went to replace the original 20in fan I got a 24. Opps, had to cut the hole bigger. Well the first 20in sounded like a helicopter taking off, when it was new, this new 24 is quieter and can't even hold the shutters open all the way. Yes, there are pressure issues here that constrain it from opening the shutters all the way, but it sure wasn't any problem for the first fan. The better motors said on them Zhejiang Crafab Electric Co LTD. The weaker new ones are also from China, but not this company. I now have 3 shutter fans with the new weaker motors, so this isn't a one off thing.
I use the 24" one to cool my 12x40 greenhouse and it works great.
Needed a small van to vent the eave of a growing house. The 24 x 24 was a great price and quality. Arrived quickly and safely. Easy to install.
