Vacuum ejectors are often used in pneumatic conveyor systems to transform positive pressure to negative—or vacuum—pressure. They are also used in many industrial robotic and automated systems, where vacuums must be created quickly and repeatedly to power motion. Choose from inline or single unit vacuum ejectors, and make sure you know the size tube you’ll be connecting it to before you shop. In addition to conveyors and robotics, vacuum ejectors are used in a variety of manufacturing and industrial machines that have pneumatic pumping systems. You can also shop for vacuum regulators, vacuum saving valves and vacuum pressure switches.
