Axial flow smoke exhaust fans are designed to handle large volumes of smoke and hot gases during a fire. These fans use an axial flow mechanism to efficiently remove smoke from building interiors, especially in structures with long, complex duct systems. They are ideal for use in public buildings, tunnels, and high-rise buildings, where effective smoke extraction is necessary for occupant safety. Their design focuses on high airflow capacity and reliability, ensuring that they function effectively under emergency conditions.
