Membrane-drying unit

All Dürr Dental compressors operate with innovative membrane-drying unit and therefore offer an unbeatable benefit: Permanent power availability. As the drying process is based on diffusion through membrane fibre layers, the normal regeneration step of conventional drying processes is eliminated.

  • Permanent power availability, no regeneration times
  • Constant dryness of the compressed air
  • Pressure dew point of ≤ 5°C at 40°C ambient temperature
  • Maintenance-free except for annual filter change
