EDWARDS E2M 0.7-28 Oil-Sealed Rotary Vane Vacuum Pumps

EDWARDS E2M 0.7-28 oil-sealed rotary vane vacuum pumps are designed to achieve low ultimate pressures, with pumping speeds of up to 27.5 m³/h. Compact and self-contained, they are particularly well suited to scientific applications, laboratories, research facilities and light industrial processes.

The two-stage E2M range combines quiet operation, proven reliability and efficient vapour handling through the use of a gas ballast valve.

The selection also includes the E1M18, the single-stage version of the EM family, offered alongside the E2M18 and E2M28 models. E2M pumps are also ideally suited for use as backing pumps for turbomolecular pumps.

Their compact design, forced-air cooling and features designed to simplify oil level monitoring, filling and draining contribute to straightforward installation, operation and maintenance.
