Our Pressure Gravity System eliminates dead zones, areas where air does not circulate, allowing your facilty to ventilate more efficiently.

A natural gravity opening mounted at either peak or high side of a building, provides a natural evacuation point for heat and fumes. The hot air and fumes must rise due to natural gravity physics.

Building pressurization through powered supply equipment provides a ventilation assist to the natural system increasing the ventilation rate. For more info on our Pressure Gravity Sytems look under the products section or call (800) 474-3267.
