D-030 - probably the quietest, smallest and most lightweight main air compressor for rail traffic

(c) IMechE / David Shirres


With 61 dB (A), 209x108x156 mm (LxWxH) and just 4.4 kg, the oil-free compressor D-030 from Dürr Technik delivers a fabulous 8 l / min at 5 bar. That's not enough for a Vectron (Siemens) or TRAXX (Bombardier) locomotive, but for EMMA.

In order to attract qualified young talent to the railway industry, the Institutional Mechanical Engineers (IMechE) annually organizes a student competition. The University of Applied Sciences Aachen enables its students to participate as a team across all disciplines.

The entry in the competition is called EMMA, an electric locomotive powered by a hydrogen fuel cell. All subsystems of the locomotive are designed, developed and improved by the students. Dürr Technik provided the students with an oil-free compressor unit D-030 from the KK8 series. The supervising professor Dr. Raphael Pfaff is convinced of the unit: "Among other things, noise emissions are assessed within the framework of the Railway Challenge. The used D-030 could be installed without further housing directly in the locomotive EMMA. Also, the compressor could be operated even during the noise evaluation in its normal regime. The noise level was so low that other teams jealously asked if it was actually working."

We are pleased about this feedback and we wish lots of success in the next competition and a good result.

With its wide oil-free compressor portfolio, Dürr Technik offers oil-free and low-noise compressors not only for EMMA but also for "real" locomotives. In addition to auxiliary air compressors, Dürr Technik   produces main air compressors up to 1200 l / min at 9 bar.
