Fan Ventilation

Greenhouse Fan systems provide positive air movement through a greenhouse, which helps to control air temperature/flow and humidity levels. As the fans exhaust the heated air, a slight vacuum is created which draws in cooler outside air through louvers, open doors and cracks. The installed fan capacity should equal at least one greenhouse volume per minute. Select fans with a high Ventilating Efficiency Ratio (VER)

Fan Location

Fan systems work best if the draw is less than 150 feet. Locate the fan so that the air flows over and through the plant canopy rather than under the benches or in the ridge of the greenhouse. The bottom of the fan or louver should be located about 3 feet above the floor for optimal air distribution. Newer greenhouse fans can provide vertical airflow and circulation, reducing energy costs over horizontal flow.
