This Edwards purge gas restrictor sets the flow rate of dry purge gas through the purge port on any nEXT turbo pump. An inert purge gas is used to protect the bearing and motor from corrosion. In order to use this purge restrictor, the vent port adapter (part number P106356) must be used to adapt the G 1/8" (BSPP) purge port to a KF10 NW10 flange. The PRX10 purge restrictor is a special KF10 centering ring with a filter and restrictor built in. This purge restrictor, as supplied, is adjusted to restrict the flow rate of dry nitrogen at a supply pressure of 25 sccm. The supply pressure can be increased to increase the flow rate. Please see the accessories download for additional information about calibrating the purge restrictor. This Edwards PRX10 purge restrictor has part number B58065001.
