PURPOSE: An ejector array and a method therefore are provided to obtain the wanted negative pressure more promptly, thereby reducing loss of energy required for supplying compressed air. CONSTITUTION: An ejector array including a panel(10) having an injection port(11) connected with a compressed air supply device, a connector(12) connected with a suction pad, and an air discharging port(13) comprises; a first ejector(20) generating minimum negative pressure and a second ejector(30) discharging maximum amount of air per unit time, that are successively accumulated in the other side of the panel; and valve plates(40) installed between the panel and the first ejector, and between the first ejector and the second ejector, and connected with valves(41,42,43,44,45) preventing the counterflow of air, wherein the accumulated ejectors are operated by compressed air supplied through a unitary injection port. |
