EH Roots pump series

Ehrler & Beck offers EH mechanical booster pumps from Edwards. Based on the proven Roots principle, EH mechanical boosters remain the preferred pumps for applications requiring high pumping speeds at pressures in the range of 0.01 to 10 mbar.
EH vacuum pumps must always be backed by another pump that can discharge against a high pressure differential to atmospheric pressure.
Application areas
- Vacuum metallurgy
- Vacuum distillation
- Vacuum packaging
- Steel degassing
- Coating
- Wind tunnels
- Space simulation
- Vacuum impregnation
- Oil drying and degassing
- Pharmaceutical freeze drying
- Industrial freeze drying
