Scroll vacuum pumps consist of both a set and an orbiting scroll. As the orbiting scroll techniques, voids are manufactured at the inlet of the pump, drawing in the gas. As the rotor Scroll Vacuum Pump additional 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 
operation as it does not require any lubrication. The bearings are separated from the compression chamber so no contamination of the pumped gas can be done. In addition, 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 may be very easily performed by the operator and with no need for special tools.
