New Dry Backing Pump Offers Ultra-Clean Operation

摘要

When is a Roots pump more than a Roots pump? When it's an ACP 20 dry pump from Alcatel High Vacuum Technology, Annecy. The Alcatel ACP 20 series is designed for oil-free, particle-free, rough-vacuum applications that require vacuum levels ranging from atmospheric pressure to 4 x 10~(-2) torr. With a pumping speed of 20 m~3/hr (12 cfm), it is ideal for backing compound turbomolecular pumps and most applications that now rely on oil-sealed rotary vane pumps, which have about the same footprint as the ACP 20.
