Differentially Pumped Rotary Feedthrough
DPRFT
The Differentially Pumped Rotary Feedthrough provides 360° of continuous rotary freedom through the vacuum wall of a UHV system.
The feedthrough has two stages of differential pumping isolated by graphite-impregnated, expanded viton seals on special sealing surfaces. A preloaded ball bearing set accurately controls the rotating stage position.
Application
The Differentially Pumped Rotary Feedthrough can be combined with manipulators and any other precision positioning devices.
