How Maximum Ventilators Work


The Maximum Ventilator is a static ventilator which is used to replace stale, moist air within the attic space with fresh outside air which is being drawn in by the ventilator through the soffit air intake located on the underside of the eaves of the building.

The ventilator functions with the combined effects of wind and pressure differentials, creating a chimney effect, thus drawing out the stale air from the attic space. Both the Turbine and the Maximum Ventilators function the same, except now the Maximum Ventilator does not have to turn to prevent rain or snow infiltrations due to it's unique, storm proof deflector built within.

That's right, the only reason the turbine is turning is to prevent rain and snow infiltrations into the attic.

Refer to a chimney with a fireplace or wood stove. Do you see anything on top of the chimney that is turning to draw out the smoke? Of course not, this is being done the same way as the ventilator, wind and pressure. If you notice, as the velocity of the wind becomes stronger, the draw also becomes greater, thus forcing you to close the damper of the chimney flue so that you do not lose all your heat.How Maximum Ventilators Work

The velocity of the wind is what activates these ventilators, but when comparing the Maximum Ventilator with the turbine, there is another flaw with the turbine, the turning of the head of the turbine is also preventing the full effect of the wind, thus reducing the drawing power and capacity of ventilation area.

The Maximum Ventilator has no moving parts, and because of the design, it captures the full effect of the wind, producing a greater drawing power thus a larger capacity of area to ventilate. The Maximum Ventilator model #301 is capable of ventilating 1200 sq. ft. of attic area, compared to the 12 inch turbine ventilator, which is capable of only 400 sq. ft.
