Master Flow rotary turbines are efficient, easy-to-install attic venting options. They allow heat and moisture-laden air to escape, helping extend the life of your roof. Upper and lower steel ball bearings provide years of trouble-free operation. The all-aluminum housing makes this 14" model lighter than galvanized turbines and resists corrosion in coastal and high-humidity climates.
