Gravity Roof Ventilator

Functioning with no moving parts the aura gravity ventilator pulls hot attic air every time the wind blows.

Gravity roof ventilator.

These ventilators provide natural ventilation and are used for intake and relief applications. Gravity roof ventilation turbo charged. The aura gravity roof ventilator dynamically removes heat from the attic in the summer and moisture from the attic in the winter. How does it work.

Designed for maximum airflow passage and weathertight integrity bgh comes in either intake or relief models with aluminum or galvanized finishes. Round mushroom style roof vent. The gravity intake and relief ventilators are non powered do not have a fan and work on pressure differential between the inside and outside of the building. An extensive range of sizes is offered with many standard and optional features.

The aura gravity roof ventilator vigorously removes heat from the attic in the summer and moisture from the attic in the winter. Built in curb cap with prepunched holes for easy attachment to roof curb. These hooded gravity roof ventilators are designed for nonpowered ventilation or can be used in conjunction with powered exhaust supply or reversible fans. Gravity intake and relief ventilators for use in non powered applications.

Bgh gravity ventilators offer a modern low silhouette design that blend with roof lines and other equipment. The dayton low profile gravity roof ventilator is designed for exhaust or supply applications on natural gravity or positive pressure systems. Brock offers two styles of gravity roof ventilators to help provide free air movement into the bin. Low profile hood has a rigid aluminum corrosion resistant construction.

The aura gravity ventilator functions like a spinning roof turbine but does not need to spin in order to work. In order to take advantage of both wind pressure and stack effect gravity ventilators are generally used in conjunction with open doors and windows to ventilate the structure. The strong weathertight hood is constructed of interlocking arched galvanized steel panels. Twin city fan offers both spun aluminum and hooded ventilators featuring a low silhouette for low roof lines.

Gravity vents are placed on the roof being the highest part of the structure to provide for exhaust of building air. The gravity intake and relief ventilators are non powered do not have a fan and work on pressure differential between the inside and outside of the building. The aura gravity roof ventilator functions much like a spinning roof turbine also known as whirlybird but does not need to spin in order to work.
