Description
The Edwards E2M28 Rotary Vane Vacuum Pump, manufactured in the United States, is a reliable and versatile vacuum pump known for its quiet operation and excellent ultimate pumping speed. It features robust vapor handling capabilities, making it suitable for a variety of applications, including sterilization, mass spectrometry, vacuum distillation, and space research. This preowned unit powers on and operates normally, achieving an ultimate vacuum of 0.004 mbar. However, the operation is noticeably loud, which may suggest some wear.

It includes a fast-acting inlet valve, NW25 inlet/outlet connections, and adjustable gas ballast control for vapor handling. The unit comes with a 2m electrical supply cable, inlet screen, Ultragrade 19 Oil, and a lifting bracket.
Technician comment
The Edwards E2M28 powers on and operates normally. During testing, the pump achieved an ultimate vacuum of 0.004 mbar. The unit is noticeably loud during operation, which may indicate wear but did not prevent it from reaching specification. The pump is preowned and was removed from a working laboratory environment. Cosmetic condition shows stains and slight wear consistent with prior use. See photos for details.
