A commercial exhaust fan is a type of fan specifically designed for commercial use. It is typically mounted on the roof of a building and is used to draw air out of the building. This type of fan is commonly used in restaurants, factories, and other commercial establishments to help keep the air inside the building clean and fresh. The exhaust fan helps to remove airborne contaminants, smoke, and other odors that can be hazardous to the health of those inside the building. It also helps to reduce the amount of heat inside the building, making it more comfortable for those inside. Commercial exhaust fans are typically more powerful than residential fans, and they are designed to handle the heavier air flow and larger volume of air that is often present in commercial establishments. They are also designed to be more durable and reliable, making them a great choice for commercial use.
