A durable wind driven turbine attic ventilator from grainger helps to remove hot attic air in summer and moisture laden air in winter. Wind driven roof mount exhaust fans designed to spin freely with the slightest breeze these fans create a vacuum that draws air out from buildings and ventilation systems no electricity required. 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. The turbine ventilator operates by utilising the velocity energy of the wind to induce air flow by centrifugal action the centrifugal force caused by the spinning vanes creates a region of low pressure area which draws air out through the turbine.

Turbine fans have angled slits cut into a capped cylinder which create a continuous fan blade. Gasoline in crawlspaces and under floor slabs.

How much air must be moved. 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. All things being equal wind driven turbine vents also known as a whirlybird roof vent do move more air than flat vents but only when the wind blows. Turbines can rotate with the breeze to help create a strong upward draft that can draw inside air up and out.
