The GAF Master Flow ERV5 Power Roof Vent is a great overall investment in attic ventilation. It can quickly 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 ERV5 model Power Roof Mount Vent can move air at a rate of up to 1250 cu. ft. per minute. It is designed for attic spaces up to 2200 sq. ft.
Energy efficient uses up to 55% less electricity than typical competitors’ vents (based on GAF testing at 120-Volt)
Helps reduce energy costs and helps prolong the life of the roof and shingles
