What is an Exhaust Fan? Exhaust fan, also known as full house fan, is often classified as an exhaust system or fan. It expels into a house or building’s attic to drag blistering fresh air out from any establishment. It also pushes it into the attic space. This fan brings an upbeat pressure disparity in the attic pushing air out through the soffit vents or gable while generating an off-putting pressure inside the structure that draws air in open area like windows. Exhaust fan also used in a kitchen to absorb the air that comes from cooking to prevent nasty smell and keep the entire house smell good.
