About EDWARDS XDS35i Dry Scroll Pump/ Tested and Fully Functional w/ 30 days Warranty
Scroll pumps are an excellent alternative to rotary vane pumps where oil free pumping is desirable. The XDS pumps in particular use an innovative bearing shield to isolate the vacuum environment from all forms of lubricant not only making them totally dry, but also protecting the bearing from any process gases. Vapour handling is enabled by an adjustable gas ballast; this allows the range of pumps to satisfy many applications that were previously off limits to other scroll pumps. Listed on ZS E/D
