The new compact EPX500 high vacuum drypump offers enhanced performance with reduced cost of ownership. Using a unique patent protected mechanism the EPX500 is capable of pumping from atmosphere to ultimate pressures of -5 Torr.

Features and Benefits

  • Compact footprint - as one of the smallest on-tool pumps available, the EPX offers outstanding savings in footprint. EPX can be mounted directly onto the tool saving foreline and installations costs or remotely if preferred.
  • Low cost of ownership - EPX requires only 1.4 kW of power and incorporating idle mode to maximize power efficiency.
  • Unique patent protected pumping mechanism
  • Ultra clean mechanism
  • Extremely reliable
  • Network compatible


  • The EPX series covers a broad range of applications from wafer handling through to medium duty processes.
  • The EPX ‘LE’ Series has been designed for use clean duty applications pumping inert gas mixtures.
