A 3 wing revolving door is a type of entrance system that consists of three flat panels that are arranged in a triangular formation around a central axis. The panels rotate simultaneously on a central spindle, allowing people to enter and exit buildings efficiently and safely. The door is designed to create a barrier between indoor and outdoor environments, preventing the influx of outside air and maintaining a consistent indoor temperature.

The system is powered by an electric motor and features sensors that control the speed and direction of the rotation, ensuring safe operation. The use of a 3 wing design provides a higher capacity and greater efficiency compared to traditional single or double doors, making it ideal for high traffic areas in commercial, public, and institutional buildings.
