ABSTRACT:
An air supply system may supply air into an elevator building and into the elevator. The system includes a number of frames each having a number of openings communicating with an air passage formed in the elevator building. One or more tubes are disposed in the elevator building for communicating with the air passage. An air generator is coupled to the tube for supplying air into the tube and for supplying air into the air passage and the elevator. A heat resistive panel assembly is secured to the wall and spaced from the elevator for forming an air chamber and for protecting the elevator from being burned by the fire.
