CTI-Cryogenics P/N 8116021G002R is an observed configured identifier for the flat On-Board 8F cryopump. The On-Board platform combines cryogenic pumping hardware with valves, sensors, heaters, microprocessor control, diagnostics, regeneration control, and remote communications. Published On-Board 8F performance is 4,000 L/s for water, 1,500 L/s for air, 2,200 L/s for hydrogen, and 1,200 L/s for argon. Replacement selection requires the complete P/N and applicable interface drawing because multiple 8F configurations and related variants exist
Configurations vary. Verify the exact unit before choosing a replacement.

Configuration and Replacement Notes
The model designation establishes the documented 8F family performance but does not define every configured interface or option.
Match the complete P/N, flange and seal standard, array type, motor orientation and phase, electronics module, gauge, valves, purge arrangement, connectors, and installation/interface drawing before substitution.
Standard, Enhanced, GLE, 300 mm PVD, and On-Board IS 8F products have separate documentation and materially different configuration details; sibling specifications are not interchangeable.
The optional keypad/display and other configurable hardware must not be attributed to P/N 8116021G002R without its label, interface drawing, or manufacturer configuration record.
