Electrical smoke exhaust skylights, as the name implies, can achieve automatic smoke exhaust. They are typically installed in the building atrium or on the exterior walls of high-rise buildings, featuring an automatic opening mechanism for the smoke exhaust window.

Generally, an electric smoke exhaust window is composed of several main components, including the sash, frame, and an automatic opening device. The automatic opening device is further made up of an opener, an alarm, and an electric controller, among other components. It can automatically open the smoke exhaust window upon detecting a large amount of smoke caused by a fire, promptly expelling toxic smoke.
