Low maintenance, corrosion resistant pumps that don't require oil.
Scroll Vacuum Pumps are low maintenence, corrosion resistent pumps that require no oil. While they can have higher up-front costs, the lifetime operation costs are much lower. It is recommended that the scrolls be changed every 40,000 hours of use. Eliminating the oil eliminates hydrocarbon contamination. Scroll pumps handle water vapor better than most types of pumps and make significantly less noise during operation.
