Greenhouse Ventilation Systems
Proper ventilation is one of the most important criteria of designing a successful greenhouse. The hot summer sun can quickly overheat a greenhouse if proper ventilation is not provided. Shutter vents and exhaust fans installed in the gable ends of the greenhouse work best to forcefully exhaust hot air.
We carry only the highest quality aluminum and PVC fans and shutters. These are not the flimsy, thin fans and shutters found with most greenhouse kits. Our greenhouse fans and shutters are designed for professional greenhouse installations.
Determine the proper size ventilation system for your greenhouse by calculating the cubic feet of air space in the growing area and plan to replenish that volume in less than two minutes for optimum cooling in summer.
Length x Width x Wall Height = Recommended CFM (Cubic Feet per Minute)
Plants will grow healthier with the proper amount of air circulation. Your greenhouse should not be drafty, but air movement should be slightly noticeable to prevent hot spots or cold spots. Good air circulation is valuable in both summer and winter and helps prevent disease.
Motorized Intake Shutter – 24” Aluminum
These high quality Aluminum Intake Shutters are hinged and balanced with such precision that the suction power of the exhaust fan on the opposite end of the greenhouse will pull the shutters open when the fan is running. The shutters then automatically close when the fan shuts off.
Solar Powered Vent Openers
These automatic vents are activated by the heat of the sun. During the day, the sun warms up a paraffin wax inside the black cylinder and expands a piston that opens the cantilevered vent. As the sun goes down and the greenhouse cools, the piston retracts and the vent closes.
