Gibraltar Building Products 1320 CFM Gable Mount Powered Attic Fan

The Gable-mount power vents operate 30% quieter and 35% more efficiently than comparable units. The fan blade is encased in a patented series of rings not a cylinder like standard units. This open ring configuration allows the fan motor to move air more efficiently and with fewer restrictions. The Gable fan uses a thermostat control to help prevent heat build-up inside the attic.
