Ventilation plays a vital role in modern greenhouses. The vertical airflow (VAF) fan, manufactured by Vostermans, produces an air current that is forced outward and downward along the roof and walls of the greenhouse and then is pulled upward through the crop. Using this type of fan can lead to a better and more uniform climate and it can also lead to energy savings. The V-Flo Fan offers growers the opportunity to reduce the negative impacts of humidity in a simple and energy-efficient way, and it is also easy to mount in a greenhouse and easy to maintain.
