Greenhouse shutters allow air to be drawn into the greenhouse by the exhaust fan.  Install low and opposite the exhaust fan.

This passive "Economy" Shutter does not require an electric motor, as it is very lightweight galvanized aluminum to open by fan draft. Louvers have felt edges.

Dayton model # 2C522C.

Attractive powder-coated brown finish for long life.

Note:  Rough opening should be square and 1/2" larger than shutter size.
