The Verti-Fan does not burden your crop. The vertical air movements are created by a ventilator that transports the air downwards in a controlled manner. The ventilator is installed at the top of your greenhouse; often a plastic trunk is attached. The air from the Verti-Fan spreads across the ground and slowly rises. It is also possible to install the vertical air circulation system in order to keep the cold air away from the window vents and cool the crop below. View the Verti-Fan brochure.
