Unlike the turbine, the 401 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 wind and pressure differentials, a “chimney effect” results in drawing the air and moisture out, replacing it with fresh new air that enters through the soffits.
| This ventilator was made
to replace faulty 12 inches turbine ventilators, but can also
replace 10 inches or 14 inches units with the use of an adaptor,
which is ordered separately.
By removing the head of the turbine and leaving the existing base flashing, it allows for an easy installation without damaging, or replacing shingles. |
