Vacuum generators are designed to create a vacuum and establish suction for purging piping systems and are widely used in the semiconductor industry. FITOK proudly introduces three series of vacuum generators: VGB Series, VGM Series, and VGC Series. The VGB series features a main structure similar to that of the VGM series but offers multiple options for inlet and vent ports, while the VGM series specifies the sizes and types of inlet and vent ports. In addition, the VGC series integrates vacuum venturi, air-actuated valve, and check valve to provide a compact design.
