GAF Announces New and Improved Green Machine(TM) High-Power Solar Roof Vent

Wayne, NJ – GAF, North America’s largest roofing manufacturer, is pleased to introduce the new environmentally friendly and energy-saving Master Flow® Green Machine™ High-Power Solar Roof Vent. The new vent offers many features and benefits to help contractors differentiate themselves, including increased airflow and improved aesthetics.

With better performance than comparable vents, the Green Machine’s 750 CFM max airflow provides up to 50% more airflow than competitive-priced solar vents.* Its simple installation makes it easy for all contractors, with virtually the same installation process as typical electric-power roof vents. Impact-resistant construction helps it to withstand hail and foreign object impact, and its standard 6-year limited warranty with 3-year Labor Protection Plus** allows both contractors and homeowners peace of mind.

Two models of the Green Machine™ High-Power Solar Roof Vent are being introduced. The Solar-Powered model has a 20-watt integral solar panel and an adjustable thermostat/humidistat, and helps to reduce attic cooling costs. The Dual-Powered model uses unique dual-power technology to switch automatically between solar and house power for 24/7 cooling during cloudy weather or at night. It uses just 1/6th the electricity of typical electric-powered vents and comes with an adjustable thermostat that features a dual-power controller.

“Historically, most solar vent products helped to save energy, but lacked the aesthetics and performance that property owners desired for their new roofing system,” stated Jeff Avitabile, product manager at GAF. “Our new Master Flow® Green Machine™ High-Power Solar Roof Vent provides property owners with a 'next-generation' solution that provides not only better attic cooling but also a finished look that will not detract from their newly installed roofing system.”
