Turbo/Maxx fits over your existing roof vent. Any roof vent can become a powerful ceiling fan! Maxxair Turbo Maxx contains a high-powered 12 volt fan and fits directly over the existing 14" roof vent for easy installation. It replaces stale air with fresh air even when it is raining. Includes three-speed fan motor for both intake and exhaust functions. The powerful 4 amp motor and 12" diameter, 10-blade fan easily removes musty air, smoke and cooking odors while preventing heat build-up, provides over 900 CFM on high speed, 680 CFM with 2.45 amp draw on medium and 500 CFM with 1.4 amp draw on low. The fan is located on the roof to drastically reduce fan noise.
