Roof Ventilator Wind Turbine

It is a free spinning roof ventilator which works by utilizing the velocity energy of wind to induce air flow through centrifugal action.

Roof ventilator wind turbine.

Aluminum wind turbine ventilators are natural air ventilation systems. Good attic ventilation is important for preventing ice dams in the winter. Depending upon the diameter of the vents and the wind speed outdoors the turbines can expel vast quantities of humid air before it becomes a problem. Unlike turbines this venting style does not have any moving parts.

A turbine has a series of vanes that spin as wind passes through them. Air vent airhawk 12 in aluminum externally braced roof turbine vent. A single 14 inch diameter turbine vent that is subjected to 15 mph winds can expel up to 1 342 cfm of air. A small 12 inch diameter turbine vent with a constant wind speed of 5 miles per hour mph can remove 347 cubic feet of air per minute cfm from the attic space.

A turbine is installed directly on the top of a roof and uses wind power to suck hot and humid air out of the attic. These can be ridge vents wind turbines or the flat vents your roofer wants to install. A small 12 inch diameter turbine vent with a constant wind speed of 5 miles per hour mph can remove 347 cubic feet of air per minute cfm from the attic space. Turbines can rotate with the breeze to help create a strong upward draft that can draw inside air up and out.
