XDS35i No Gas Ballast variant has had the gas ballast feature removed for applications such as rare gas recirculation and gas recovery.
The XDS46i shares many of the same features of the XDS35i but with a peak speed of 40 m³/h. The pump has been optimised for maximum pumping speed at inlet pressures between 1 mbar and 10 mbar, making it well suited for backing turbomolecular pumps.
For more aggressive applications, ‘C’ variants are available which features Chemraz® internal valves and stainless steel fittings for extra protection from the pumped media.
