Edwards E2S Rotary Vane Pumps
The Edwards E2S Series is a range of two-stage oil-sealed rotary vane vacuum pumps designed for medium vacuum applications. The range includes E2S45, E2S65, and E2S85 models, combining high pumping speed, vapour handling, and simplified operation. ACFM supplies these Edwards pumps for applications such as vacuum degassing and drying, heat treatment, vacuum insulation, leak testing, gas handling, research, and backing of high-vacuum pumps or systems.

E2S Rotary Vane Pump Features
Applications
Applications may vary depending on the E2S model and system configuration.
E2S Pump and Booster Combinations
Standard combinations of E2S two-stage rotary vane pumps with Edwards EH mechanical boosters are available for higher-capacity requirements. The E2S45, E2S65, and E2S85 can be combined with EH250, EH500, and EH1200 boosters. The E2S85-EH1200 combination can provide up to 900 m³/h effective speed and reach an ultimate vacuum of 3 × 10⁻⁴ mbar.
