Dry Scroll Pumps
Dry scroll vacuum pumps are positive displacement pumps that use two spiral-shaped scrolls, one fixed and one orbiting, to trap and compress gas molecules. They are oil-free, low maintenance pumps that are commonly used for clean vacuum applications. Since they do not rely on oil for sealing and lubrication, they eliminate the risk of oil contamination and leakage, making them an environmentally-friendly choice.

We in Edwards are driving scroll technologies to its best and we are committed to offer the most sustainable solution now and in the future.
