During summer months, attic temperatures can reach 150 degrees F. High temperatures cause an increase in temperature in the living space and an increase in energy consumption by air conditioning equipment. Forced ventilation will circulate cooler air through the attic space and lower the temperature. Fan and solar module combinations allow daytime ventilation and air circulation anywhere the sun shines. They are great for greenhouses, kennels, barns and attics where AC power is not available. The solar module runs the fan at full power in full sun and at a slower speed in overcast weather.
Operation is automatic.
When the sun shines on the solar module, the fan begins to operate. The Attic Roof Ventilator is self contained. This kit includes the fan, an 18 watt solar module and 20' of wire. The fan can deliver 1000 CFM when the module is in full sun. The reversible, ballbearing PM motor allows the fan to be used for intake or exhaust by reversing the wire at the motor.
