The new Master Flow Green Machine High-Power Solar Roof Vent features a 750 CFM max airflow that provides up to 50 percent more airflow than competitively priced solar vents. Impact-resistant construction helps this product withstand hail and foreign objects and a standard six-year limited warranty with three-year Labor Protection Plus gives contractors and homeowners peace of mind. GAF is offering two models: a solar-powered model and a dual-powered version that switches automatically between solar and house power for 24/7 cooling.
