Gravity Roof Ventilator

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

Gravity roof ventilator.

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. 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. An extensive range of sizes is offered with many standard and optional features. Bgh gravity ventilators offer a modern low silhouette design that blend with roof lines and other equipment.

These hooded gravity roof ventilators are designed for nonpowered ventilation or can be used in conjunction with powered exhaust supply or reversible fans. 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. Designed for maximum airflow passage and weathertight integrity bgh comes in either intake or relief models with aluminum or galvanized finishes. How does it work.

The aura gravity ventilator functions like a spinning roof turbine but does not need to spin in order to work. Brock offers two styles of gravity roof ventilators to help provide free air movement into the bin. The brock elbow style roof vent offers 190 square inches 1225 square centimeters of ventilation opening. The dayton low profile gravity roof ventilator is designed for exhaust or supply applications on natural gravity or positive pressure systems.

Gravity intake and relief ventilators for use in non powered applications. Twin city fan offers both spun aluminum and hooded ventilators featuring a low silhouette for low roof lines. Gravity roof ventilation turbo charged. Gravity vents are placed on the roof being the highest part of the structure to provide for exhaust of building air.

The aura gravity roof ventilator dynamically removes heat from the attic in the summer and moisture from the attic in the winter. 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. The strong weathertight hood is constructed of interlocking arched galvanized steel panels.

Gravity ventilation gravity ventilators are used to equalize a building s positive or negative pressure created by other fans in the system. These ventilators provide natural ventilation and are used for intake and relief applications. Low profile hood has a rigid aluminum corrosion resistant construction.
