E2M0.7

The E2M0.7 is a small two stage oil sealed rotary vane pump that features a very low sound level of only 43 dB(A), compact dimensions, low energy consumption and low operating temperature. It will appeal to scientific instrument manufacturers and laboratory users for backing small turbomolecular or diffusion pumps as well as general laboratory applications.

Fitted in a cabinet, the pump will be virtually inaudible and the low operating temperature will minimize the heat load on the equipment. Vertical vacuum inlet with horizontal option.

Features and Benefits

  • Very low sound level of only 43 dB(A).
  • The pump is designed for reliable, long-term operation.
  • Compact dimensions.
  • Low energy consumption.
  • Low operating temperature will minimize the heat load on the equipment.
  • The pump is a free-standing unit.
  • The motors are totally enclosed and are cooled by the motor-cooling fan.
  • Pressure die cast oil box with integral oil seals prevents oil leaks.
  • Gas ballast valve for large water vapor handling capacity.
  • Externally approved to EN61010, CSA, C22.2 and UL61010.
