This is a vacuum pump, each unit comes with two pen-type tubes, several tips, and a flexible hose. Both can be used simultaneously, for example, for two workers to share on the assembly line. The air pressure can be adjusted via the knob. The pump is powered by 220VAC, so if you do not have this voltage, we recommend a 110VAC to 220VAC step-up transformer.
This air vacuum suction pump is commonly used for electronic equipment repair, and its function is to hold SMD integrated circuits on electronic boards; you can also use it for your electronics projects.
