Anatomy of a Butterfly Damper
Butterfly dampers consist of a round blade, seals, packing, a bearing, an actuator, and a shaft.The shaft plays a large part in a Butterfly damper's operation, as it intersects the linkage, bearing, packing, and blade.
How doButterfly Dampers Work?
Butterfly dampers use a round blade that moves upwards and downwards, opening and closing to start or stop airflow as needed.
Butterfly dampers can withstand extreme pressures, acidic applications, and very high temperatures (up to 1800°F). This makes them great for use in corrosive environments and abrasive air streams such as wastewater treatment.
