Shutters & Air Intakes
Schaefer Shutters & Air Intakes
Schaefer Ventilation Equipment offers many different types of shutters, shutter fans and air intakes. Fresh air should enter the greenhouse from the opposite end of the exhaust fans. This is typically done with mechanical shutters. There are many factors, formulas, and recommendations but for the sake of simplicity a very easy rule of thumb is to use one inlet shutter per fan installed, and use one shutter that is 6" bigger than the fan.
For example: You installed two 12" fans, install two 18" inlet shutters
