The RV Series provides four models with different pumping capacities and features such as two-position gas ballast, positive-pressure oil lubrication, and automatic inlet-valve protection.
The E2S Series includes three models and can be combined with Edwards EH boosters for additional pumping speed and improved ultimate pressure.
The E2M Series includes four larger models with HC, FX, AZ, and EX configurations. These variants address standard hydrocarbon-oil operation, oxygen-rich applications, azide compatibility, and explosive atmospheres.
The E2M0.7, E2M1.5, and E2M2.5 provide compact options for scientific and laboratory applications and small turbomolecular pump backing.
