A wireless pneumatic safe device includes an actuated tube mounted on a lower edge of an electric rolling door. The actuated tube has a closed chamber longitudinally defined therein. A hose communicates with the chamber. A control unit is mounted on the electric rolling door. The hose is further connected to the control unit for transmitting a compressed air from the actuated tube to the control unit. The control unit transmits a disconnection signal or a reversal signal when receiving the compressed air from the actuated tube. A radio receiver is mounted to and electrically connected to a motor. The radio receiver transmits a disconnection order or a reversal order to the motor for stopping or reversely operating the electric rolling door for achieving a purpose of safety when receiving the disconnection signal/the reversal signal from the control unit.
