The GAF Master Flow ERV4 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 ERV4 model Power Roof Mount Vent can move air at a rate of up to 1000 cu. ft. per minute. It is designed for attic spaces up to 1600 sq. ft.
Energy efficient uses up to 55% less electricity than typical competitor's vents (based on GAF testing at 120-Volt)
Helps reduce energy costs and helps prolong the life of the roof and shingles
Miami-Dade County Product Control approved, State of Florida approved, and meets or exceeds the requirements of Texas Department of Insurance
