Pneumatic barrier equipment

Abstract

The invention relates to a pneumatic barrier device that saves air and energy. This pneumatic barrier device comprises a pneumatic assembly, shaft, switches, barriers, and actuators, in which the pneumatic assembly includes an air supply chamber connected to an air compressor, a starter and an electrical control unit, a shaft mounted on the starter, and switches mounted on the starter. Furthermore, the electrical control unit is electrically connected to the switches, and the barriers are mounted on one side of the shaft. Two switches control the barrier, and the barrier raising and lowering shaft. The drive mechanism is located on the other side of the shaft; the air chamber supplies air to the drive mechanism to operate and control the shaft.
