The EPX is a unique pump, patented and designed by Edwards, that is capable of pumping from Atmospheric pressure to 10⁻⁴ and 10⁻⁶, and ideal even in demanding cycling applications
In a single pump, thanks to a unique and patented mechanism designed and manufactured by Edwards
EPX is smaller than the equivalent
turbomolecular pump and primary pump combination
EPX pumps have no oil or grease under vacuum and present no other source of potential contamination
The EPX series uses a unique, patented, single-shaft regenerative and Holweck® stage mechanism

The EPX series uses a unique, patented, single-shaft regenerative/Holweck® stage mechanism that makes them capable of pumping from atmosphere to ultimate pressures of <1x10⁻⁴ mbar or <1x10⁻⁶ mbar depending on model. They are ideal for applications where a better base pressure is required than can be delivered by a typical primary pump and where otherwise a turbomolecular pump and primary pump would be required and also for applications that cycle frequently from atmosphere to low pressures as they can operate continuously at all inlet pressures.
Product Features
COMPACT FOOTPRINT
EPX is smaller than the equivalent turbomolecular pump and primary pump combination.
HOLWECK AND REGENERATIVE STAGES
for wide range performance with low heat and vibration.
ULTRA CLEANMECHANISM
EPX pumps have no oil or grease under vacuum and present no other source of potential contamination.
WATER COOLED
for a low environmental head load.
ADDITIONAL HELICAL ROTOR STAGE (EPX500 ONLY)
for increased speed and 1x10⁻⁶ mbar capability.
NITROGEN PURGE FACILITY (N VARIANTS)
which makes them suitable for pumping vapours and low levels of corrosive vapours and particulates.
