Exhaust Fan

An exhaust fan is a mechanical device designed to remove stale air, smoke, heat, odors, and moisture from an indoor space, improving air quality and ventilation. It works by drawing air from the room and expelling it outside, creating a flow of fresh air. Commonly used in kitchens, bathrooms, workshops, and industrial settings, it helps prevent dampness, mold growth, and accumulation of harmful gases. Exhaust fans come in various sizes and designs, including wall-mounted, ceiling-mounted, and window units. They can be powered electrically or connected to building ventilation systems. Some models include filters to trap dust and pollutants. The fan’s blades rotate at high speed to maximize airflow efficiency. Many modern units are energy-efficient and operate quietly. Overall, exhaust fans are essential for maintaining a healthy, comfortable, and safe indoor environment.
