It is available with rough (3 mbar) or high (10–6 mbar) vacuum capability. The 8 × 8-in. unit is mountable in various configurations and movable while in operation. Although the system uses a turbo pump to achieve ultimate pressure, it does not employ some of the standard operating procedures of a turbo pump. The device includes a quick-connect inlet flange of NW 25. The pumping speed is 11 l/s for nitrogen, 6 l/s for helium and 4 l/s for hydrogen.
