Scroll vacuum pumps contain both a set and an Scroll Vacuum Pump orbiting scroll. As the orbiting scroll techniques, voids are manufactured at the inlet of the pump, drawing in the gas. As the rotor further moves, the gas is usually steadily compressed until it is discharged to atmosphere at the pump exhaust.

The scroll pump design provides 100% oil-free procedure as it will not require any lubrication. The bearings are separated from the compression chamber therefore no contamination of the pumped gas can be done. Furthermore, the leak-tight design helps prevent contamination of the pumped gas by ambient air flow. Maintenance is bound to changing the scroll suggestion seals which can be very easily completed by the operator and with no need for special tools.
