The GAF Master Flow ERV6 Power Roof Vent with built-in humistat/thermostat is a great overall investment in attic ventilation. It can efficiently remove a larger volume of hot and/or humid air from your attic when compared to static ventilation. This in turn can help save money on your heating and cooling costs. The ERV6 model Power Roof Mount Vent can move air at a rate of up to 1500 cu. ft. per-minute. It is designed for attic spaces up to 2800 sq. ft.
