Gravity ventilators are an important part of a building’s ventilation system. They are designed to allow fresh air to enter the building while simultaneously expelling stale air. Gravity ventilators work by using the natural forces of gravity and wind to draw in fresh air and expel stale air. The ventilator has an intake and an exhaust, with the intake located at the highest point of the building and the exhaust located at the lowest point. The intake allows fresh air to enter the building, while the exhaust allows stale air to escape. This process helps to keep the air inside the building fresh and healthy. Gravity ventilators are often used in commercial and industrial buildings, as well as in residential homes. They are an effective and efficient way to keep the air inside a building fresh and healthy.
