Powerful Two-Surgery Performance in a Compact Design
The Duo delivers approximately 125–145 l/min at 5 bar, with a 20-litre tank and noise levels reduced to just 51 dB(A) when housed. It is oil-free, quiet, and engineered for long service life with minimal maintenance. Dürr Dental has led innovation in dental compressed air since 1965, setting the benchmark with its oil-free piston technology and advanced air-drying systems.
Advanced Membrane Drying
The integrated membrane drying unit provides a continuous flow of dry, hygienic compressed air. Unlike conventional dryers, there is no regeneration downtime, ensuring uninterrupted performance even under heavy use.
Durable Piston Technology
The Duo’s pistons and cylinders are engineered from wear-resistant materials, allowing them to operate without oil-based lubrication. This ensures hygienic air quality, protects dental instruments, and guarantees efficiency for years to come.
Flexible Growth with the Tandem Concept
 
For practices planning to expand, the Duo can be upgraded to a Duo Tandem configuration. This modular system doubles output and ensures operational security by providing redundancy, so your practice never faces downtime.
