Vacuum Generators, Vacuum Ejectors（Additional Function：Reverse Check Valve (Vacuum Retention)）

Vacuum generators and ejectors are machines that generate a vacuum. Vacuum generation methods are different, and vacuum generators are used to create a vacuum using compressed air and carry it by suction. When the compressed air flows into the diffuser, it is jetted at a high speed and the pressure drops, creating a vacuum. It is composed of a nozzle and a diffuser, and the degree of the vacuum pressure changes depending on the shape and dimensions. Ejectors, on the other hand, use water, steam, oil, etc. to create a vacuum. This is a mechanism in which the material that has been heated and turned into steam is injected at a high speed, so that the lower stage is compressed. It consists of jets, cylinders, boilers, pipe heaters, heat insulators with different widths, etc. The ejected steam is cooled and returns to the boiler again. Shapes and performances vary depending on the type, such as those with a solenoid valve, elbow type, and compact type.

Vacuum Unit, Ejector System ZK2 Series

SMC

A vacuum unit ejector system manufactured by SMC
[Features]
· Built-in digital pressure switch for vacuums, with energy-saving function. Cuts the air supply upon reaching vacuum: Leading to 90% reduction in air consumption
· Has a 2-stage ejector structure that increases suction flow rate by 50% and reduces air consumption by 30% (compared to SMC's single-stage ejectors)
· Compact and lightweight, with a 28% reduction in volume (88 cm³) and a 59% reduction in weight (81 g) compared to conventional products
· Reduced wiring for single units as well as manifolding.
· Once the supply valve is switched ON, the vacuum generation state is maintained even if the power is cut off. This reduces power consumption.

Vacuum Unit, Vacuum Pump System ZK2 Series

SMC

Vacuum pump system, vacuum unit with digital pressure switch for vacuum and energy-saving function.
[Features]
· Supply air cut when vacuum achieved: Air consumption reduced 90%.
· Compact and lightweight: Size reduced by 28% (88 cm³) and weight by 59% (81 g).
· Reduced wiring for both single units and manifolds.
· Once the supply valve is switched ON, the vacuum generation state is maintained even if the power is cut off. This helps reduce power consumption.
