Single Crankpin - Anest-Iwata, Edwards, Leybold, Ulvac, Varian-Agilent Part# 71004006S

The use of the crank pin allows the scroll elements to maintain a fixed phase relationship and ensures that the gas is trapped, compressed, and expelled in a continuous and efficient manner. This design results in a vacuum pump that is oil-free, reliable, and capable of achieving high levels of vacuum in various applications, such as semiconductor manufacturing, laboratory equipment, and vacuum packaging.
