This Greenhouse Ventilation Exhaust Fan System is available in three sizes. The size you choose is dependent on the size of your greenhouse. This fan system can be used with virtually all greenhouses! No matter how big or small your greenhouse is, air circulation and ventilation is critical to the well being of your plants.
The exhaust fans are quiet and corrosion resistant, UV protected and maintenance free. Place the motorized intake shutter (s) on the end wall opposite the shutter fan. When the fan turns on, the thermostat also opens the shutter to supply air across the length of your greenhouse. Place the fan as high as possible and the intake shutters as low as possible.
This shutter fan measures 12" and includes one intake shutter and one greenhouse cooling thermostat.
Also available in 16" and 20" sizes. The two larger sizes include two intake shutters and one greenhouse cooling thermostat. Check sizing below.
