Greenhouse Ventilation Design

Features of Greenhouse Ventilation Systems

We suggest you place the exhaust fan up high in one end of the greenhouse. Place the shutter(s) down low on the opposite wall. Wire them to a one stage thermostat or two stage thermostat.  This will enable your greenhouse ventilation system to give you the most efficient flow of air throughout the entire greenhouse. The motorized exhaust fans have an aluminum blade and pvc shutter. The heavy duty motors are totally enclosed and maintenance free. The motorized intake shutters are exterior grade PVC for a maintenance free unit. This will also resist rust and corrosion. The louvers are curved for a tight fit when closed. Corners are fused together for strength and durability. Greenhouse ventilation systems may be easily retrofitted in a polycarbonate greenhouse. But, we highly recommend purchasing them at the same time as a glass greenhouse.
