When the air supply is insufficient, the motor speed of the air blower 6 can be controlled according to the situation.

[0018] The controller is a controller that can be programmed, such as a PLC or a microcomputer controller. In this way, the air supply of each air blower 6 at the supply end can be adjusted according to the use state and air consumption parameters of the energy-using device 10, and whether to supply air to the energy-using device 10, so as to coordinate the demand between each unit and the energy-using end, and achieve the best energy-saving state and the longest service life.
