How To Choose a Roughing/Backing Pump for the Turbo and

The pump has to, first, rough pump the chamber from atmospheric pressure to a low enough pressure to allow the high vacuum pump to operate, and then it has to revert to a secondary position where it supports the high vacuum pump by providing a low enough pressure at the high vacuum pump’s outlet or exhaust....<<more>>
