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 < 1x10-6mbar 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.
Features & Benefits:
Compact footprint – the EPX is more compact than the equivalent turbomolecular pump and primary pump combination.
Low cost of ownership – zero routine maintenance with a 5 year service interval.
Unique patent protected pumping mechanism – the EPX can pump down from atmosphere to turbomolecular base pressure and can operate continuously at all inlet pressures. No separate “rough pumping” required.
Ultra clean mechanism – EPX pumps have no grease or oil under vacuum and present no other source of potential contamination.
Extremely reliable – based on field proven IPX technology, the EPX has a MTBFp = 13 years (SEMI E10) with service periods of around every 5 years to maximize the life of the pump.
Water cooled – low environmental heat load
Low noise and vibration – better working environment. Ideal for vibration sensitive environments.
