  • Large, clearly marked, easily accessible controls
  • Operate at quiet 48dBA
  • Easy to use and service (require no special tools)
  • Fast-acting inlet valve prevents oil and gas suckback in the event of power or oil pressure loss
  • NW25 inlet/outlet connections
High vacuum or high throughput from the same pump
  • Easily selectable modes
  • High Vacuum mode provides ultimate vacuum down to 1.5 x 10-3 torr with no gas ballast
  • High Throughput mode sustains long-term high inlet pressures with ultimate vacuum as low as 2.3 x 10-2 torr without gas ballast
Adjustable gas ballast control maximizes vapor handling capability
  • Gas ballast delivered into pump prevents condensation of vapor carried by pumped gases
  • Three user-selectable gas ballast positions—'0' Closed, 'I' Low Flow, 'II' High Flow—meet most vapor handling requirements
