Overview

Edwards E2M series two stage oil sealed rotary vane vacuum pumps are renowned for their high ultimate vacuum, rapid pumping speeds, quiet operation and ability to handle water vapour. These direct drive rotary vane pumps are inherently compact and vibration free, and with their finger-proof fan and coupling housings they offer excellent operator protection.
A comprehensive range of accessories is available to allow use on a wide variety of vacuum applications.

Supplied with Ultragrade 70 Oil. Fomblin® must be purchased separately for PFPE prepared pumps E2MFX.
