Edwards E2M28 Two Stage Rotary Vane Vacuum Pump – 19.5 CFM, 115/200-230V 1-Phase with IEC60320 Connector (A37317984)

The Edwards E2M28 (part number A37317984) is a high-capacity two-stage oil-sealed rotary vane vacuum pump from the reliable EM series. This single-phase model features a convenient IEC60320 power connector and supports 115/200-230V 50/60 Hz, making it easy to install in laboratory and light industrial environments.

With a strong pumping speed of 19.5 CFM (33.0 m³/h) at 60 Hz and an excellent ultimate vacuum of 1 × 10⁻³ mbar (7.5 × 10⁻⁴ Torr) without gas ballast, the E2M28 delivers faster pump-down times and deeper vacuum than the smaller E2M18 models. It offers superior vapor handling, quiet operation, and proven long-term reliability for demanding roughing and backing applications.
