Unlike the turbine, the 303 static ventilators do not require to rotate to prevent water or snow infiltrations. Its unique patented deflector system prevents infiltrations while at the same time capturing the wind flow from any direction and at velocities as low as 4 miles/hr. With the combination of technology, wind and pressure differentials, a “chimney effect” results in drawing the air and moisture out and replacing it with fresh new air that enters through the soffits.
| With as little as a four miles per hour wind, this ventilator is creating an air exchange rate of 266 C.F.M. |
