Sloped Roof Ventilator, 303, Grey

Unlike the turbine, the Maximum Ventilators are CSA approved and do not require to rotate to prevent water or snow infiltrations. Its unique storm proof system prevents infiltrations while at the same time capturing the wind from all directions and at velocities as low as 6 km./hr. (4 mi./hr.). With this combination of technology, wind and pressure differentials, a “chimney effect” results in drawing the stale air and moisture out of the attic space, while replacing it with fresh new air that enters through the soffits.

The model VMAX-303 has been designed for slope roof application and is compatible with most all types of roofing membrane including metal. It has no moving parts, requires no electricity, and is completely silent and maintenance free. Built tough to endure the harshest weather conditions that nature has to offer including hail storms. It sits high enough off the roof deck to allow it to weather through snow accumulations without being covered, thus, finally giving the home owner a peace of mind.
