A ventilation system is an important part of any home or business, as it helps to keep the air inside clean and fresh. An exhaust fan ventilation system is a type of ventilation system that helps to remove stale air, odors, and pollutants from a room or building. It works by drawing in fresh air from outside and pushing out the stale air through an exhaust fan. The fan is typically installed in the ceiling or wall, and is connected to a duct system that carries the stale air outside. Exhaust fan ventilation systems are a great way to keep the air inside your home or business clean and fresh, while also reducing energy costs. They are also an effective way to reduce the risk of airborne diseases, as they help to remove pollutants from the air.
