Aluminum Roof Wind Ventilators

This Aluminum Roof Ventilator is guaranteed for long lasting performance. Constructed from light-weight aluminum as it has 1/3rd the weight of steel and thus the inertia required to move the ventilator from stationary position is much less. Aluminum being highly ductile and malleable facilitates complex design of airfoil blades of the ventilator. These exclusive blades are designed to generate maximum resistance to the wind flow thus producing the rotational push. The Airfoil blades also incorporate intricate grooves that guide out the rain water falling on it and prevents the same from percolating inside the premises.
