Silver Airline - Compressed Air for CAD CAM Systems
Optimally suited for continuous operation of milling and grinding machines
Milling and grinding machines place particularly high demands on the compressor in terms of reliable and constant supply of compressed air. Constant oil-free, clean and dry compressed air is the top priority for operation - because the milling machine does not allow any breathers during operation.
Membrane drying unit
The duty cycle of a compressor unit during operation with a milling machine far exceeds the duty cycle in normal dental practice operation. Thanks to the innovative membrane drying system from Dürr Dental, no regeneration times are necessary. This ensures constantly dry compressed air in continuous operation.

Compressed air quality according to ISO 22052 Chap. 5.3.
Manufacturers of CAD/CAM systems make clear specifications for the quality of the connected compressed air supply regarding particle, oil and water content. Moist compressed air can cause damage to the CAD/CAM system. Oil can also impair the quality of the milling result. With our membrane drying and bacteria filter, Dürr Dental compressors produce dry and oil-free compressed air – for the optimal result of your work.

The Tandem Principle
The electronic control of the tandem compressors allows easy adjustment of the pressure range. The two independently operating units ensure operational reliability. If the demand for compressed air increases, it is possible to connect a second tandem compressor to the same compressed air network.

Operational safety with VistaSoft Monitor
With the help of the cloud-based IoT application VistaSoft Monitor, the condition of the compressor can be checked anywhere and at any time. You and participating dealers are also immediately alerted to upcoming maintenance/inspections. If action is required, you will receive an alert immediately.

Firmware
The new firmware offers more flexibility by extending the pressure range setting from 9 to 9.5 bar.

This recommendation applies to a 1:1 connection between CAD/CAM system and compressor. If there are other (e.g. workstations for technicians), these will have an effect on the correct choice of compressor and must therefore be taken into account accordingly. To avoid pressure fluctuations caused by other air consumers, it is recommended to operate the CAM system via a separate compressed air network with a dedicated compressor. Adjusting the pressure range on the compressor and setting the correct operating mode is also essential. The Duo Tandem is available with optional sound insulation.
