Oil-free Compressors - E-Bull Series

Our small powerful compressor package for commercial vehicles, rail vehicles and a wide range of industrial applications

With the next generation of the E-Bull, Dürr Technik is optimising its innovative range of oil-free piston compressors, which are specially designed for rail and commercial vehicles such as trains, trucks and buses and as well as for industrial applications.

In the field of mobility, where every gram counts, the low weight of the E-Bull reduces energy consumption and increases payload. With a power consumption of only 10.6 watts/l/min, the next generation oft this versatile piston compressor belongs in the upper efficiency class. Despite its high performance, it is extremely quiet and makes a significant contribution to reducing noise pollution. Thanks to its compact dimensions, the compressor can be installed anywhere in the vehicle - in any installation position.

High-quality materials and our know-how in oil-free technology ensure low-maintenance operation and an extremely long service life, which is also reflected in low life-cycle costs. The robust design of the E-Bull can withstand strong vibrations and is therefore ideal for mobile applications. Dürr Technik has been an innovative network partner for the German initiative “e-mobil Baden-Württemberg” since 2017 and supports joint research and development projects on electromobility.

With our oil-free compressors you can fully rely on an environmentally friendly solution that combines sustainability, energy efficiency and reduction of CO2 emissions.

Press article about the new generation of compressors

Mouldi Warag, Product Manager at Dürr Technik, on the new generation of oil-free electric compressors:

“These developments might not sound like much at first, but it’s actually really impressive in the context of starting with an already very compact compressor.”

Your benefits at a glance

Robust & durable
  • New: Optimised heat dissipation using new rotating head design
  • Withstands even strong vibrations and is therefore ideally suited for mobile applications
  • Well protected against dust and water with degree of ingress protection; IP 67
  • Extremely long service life thanks to high-quality materials and low-friction oil-free technology
  • Application temperature range from -40°C to +50°C
Powerful & efficient
  • New: 11% higher flow rate compared to the previous model with lower weight (as low as 0.1 kg per l/min depending on application)
  • Suitable for operation with frequency inverter. The inclusion of a variable speed drive (VFD) means that the compressor only runs at the required output, saving power and reducing noise
  • Long lift: guaranteed 100% duty cycle
Compact & quiet
  • New: Even less space required thanks to internal air ducting
  • Variable mounting positions
  • Extremely quiet compared to other piston compressors
Economical & environmentally friendly
  • New: Even more sustainable with a 6% reduction in power consumption
  • Cost savings in oil, filter and and the disposal of waste oil thanks to oil-free technology
  • Low lifecycle costs due to robust and reliable design. Low requirement for spare parts.
  • Low-maintenance operation and extended maintenance intervals as oil level checks and oil changes are no longer necessary
  • Environmentally friendly thanks to low energy consumption and high effiecency motors, specially IE3.

The benefits of the new compressor range in detail:


Increased Flow Density

Despite its lower power consumption and reduced height, the new E-Bull now produces 11% more air than its predecessor.

Improved Heat Dissipation

The new design of the compressor heads ensures faster heat dissipation. The new head rotation option allows airflow to be optimised according to the compressor's installation position.

Lower power consumption

The power consumption of the compressor has been reduced by 6%. This not only reduces heat production, but also also improves the E-Bull's sustainability credentials.

Reduced height thanks to integrated air ducting

The new air guide, which is fully integrated into the crankcase, reduces the overall height of the compressor and significantly lowers the outlet temperature of the compressed air. This is particularly advantageous when the compressor is integrated into stations or installed in low height machine rooms.

The E-Bull compressor - perfect for many industries


The E-Bull: the ideal train companion.

You can rely on the E-Bull in any situation. The compressor is a compact powerhouse that is quiet, low maintenance, reliable and meets the latest railway standards. The E-Bull compressor is ideal for integration into modern compressed air systems for new trains or for retrofit projects.

Systems based on one or more compressors and in combination with coolers, dryers, electrical and pneumatic controls can be integrated easily due to the low height and flexibility of the arrangement. Compressed air stations can be designed exactly to customer requirements and sized flexibly according to vehicle consumption.

Please contact us for further information.

The E-Bull: Powerful support for modern commercial vehicles.

Electrically powered trucks and buses require compact, efficient and environmentally friendly compressors that are corrosion resistant and extremely reliable. The new E-Bull compressor meets all these requirements.

Excellent driving comfort: low noise and vibration thanks to balanced moving parts and high-quality vibration dampers.
Premium motor: high protection rating up to IP67 and high efficiency motor up to IE3.
Small and compact dimensions: ideal for installation where space is limited. Contact us now to arrange a consultation.
