Simple, yet powerful rotary vane pump to boost your production not your expenses
E2S range - E2S45, E2S65 and E2S85 - perfectly balances performance, cost and usability. A reliable piece of engineering, simply made, well suited for many standard applications that require medium vacuum. It pumps down fast, it handles vapours and it contributes to minimising noise level in your workplace.
Standard combinations of E2S two stage rotary pumps and EH mechanical boosters are available for high-capacity demands. Factory pre-assembled, these pumping systems are compact, mobile and easy to use. With a direct start from atmospheric pressure our E2S85-EH1200 stack provides 900 m3/h (@60Hz) effective speed and allows to reach high vacuum range with an ultimate vacuum of 2x10-4 mbar.
