If the humidity level in the outdoor weather is high during the night hours when the ventilation covers are closed or when the weather conditions are rainy and cloudy, the humidity level in the greenhouse interior environment rises and creates a risk for the disease in the plants.
Circulation fans are of great importance to ensure air circulation and climate balance in the greenhouse and to distribute high humidity. 1 circulation fan is required for every 400 m2.
Circulation fans can work with remote control automatically as integrated to the automation system. The fans are made of galvanized steel sheet or plastic according to their characteristics and provide air flow in the range of 3.500 m3 to 7.500 m3 according to the feature of the selected fan.
