Dry scroll pumps are specialized vacuum pumps designed to create a stable and oil-free vacuum environment. Unlike traditional vacuum pumps that rely on lubricants, dry scroll pumps use a pair of interleaving spiral elements (scrolls) to compress gases mechanically. This design eliminates the need for oil or other lubricants in the pumping chamber, reducing contamination and maintenance requirements.
