Motorized aluminum shutters used as outside air intake or free-air exhaust when connected to a controller. Outdoor air is drawn in through this motorized shutter and hot air is exhausted through a motorized shutter fan. Can also be used as exhaust shutter with an evaporative cooler.

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.
Heavy gauge aluminum high quality shutter! Sturdy, and strong this shutter will last for years and years!
As always dealing with GMS and my Sales Rep River, made this purchase as perfect as it could be!
So far, so good! I bought a pair of these to replace some PVC louver shutters that completely failed during a "bomb cyclone" we had in March 2019. These aluminum ones are a more rigid material, so they don't have the problem of flexing in high winds and blowing apart. They've already been through 50 mph winds with 60 mph gusts, and I do not anticipate that they'll have any problems with the 80-100 mph winds we sometimes get here, but time will tell. One word of advice though, they will flop open if hit with a direct blast of wind, so if that's a problem in your area, you might want to install a protective barrier over them when it's very windy.
