  • Automatic self-cleaning purge maintains efficiency, extends diaphragm life
  • Free air displacement: 35 L/min (1.2 CFM)
  • Incremental ballast switch enables fast response to bumping/foaming
  • Inlet and exhaust separators protect pump and lab air from contaminants
  • Select 9 torr model for atmospheric B.P to 120°C; 2 torr model to B.P. 160°C
