Oil-free DC compressors
Meeting the highest demands with high tech: DC Compressors from Dürr Technik
Compressors are used in many areas of everyday life. Few people know that they also play a role in buses and trains to get people safely from A to B.
Piston compressors are the preferred choice for mobile applications because they are particularly durable and reliable. Thanks to the sophisticated oil-free technology that Dürr Technik uses in all its compressors, Dürr Technik's oil-free DC compressors are also particularly low-maintenance. For these reasons, our oil-free DC compressors are popular with our customers in the marine, automotive, construction equipment and many mobile industrial applications.
Another prominent example is rail transport. Train manufacturers use oil-free DC compressors primarily for auxiliary air applications. They are also reliable in continuous operation. With no need for oil level checks or oil changes, the units are maintenance free. The operator also saves the cost of servicing and disposing of used oil. The use of high quality materials ensures minimal wear and tear, resulting in above average component life.
Advantages of our oil-free DC compressors
- Maintenance-free, cost-saving and environmentally friendly due to oil-free technology
- Higher availability and less downtime - oil-lubricated, older models require more maintenance
- Wide range of powerful DC compressors with different voltages
- 100% duty cycle S1 even under extreme climatic conditions from -40°C up to +70°C
- Simple installation - perfect for retrofit use
Oil-free DC compressors for industrial and automotive applications
Industry: Our oil-free DC compressors are used in all branches of industry, e.g. food industry, beverage industry, metal industry, paper industry, printing industry, pneumatic conveying, cement industry, mechanical engineering and many more.
In the automotive sector: There is a wide range of applications, e.g. for lifting devices, inflating tyres, opening doors, but also for exhaust gas treatment or trailer brakes.
Oil-free DC compressors in the rail sector
For example, to operate toilet doors, sanding systems, wheel flange lubrication or the signal horn. Complete auxiliary air supply systems lift panthographs. Train manufacturers primarily use oil-free DC compressors for auxiliary air applications. They are reliable even in continuous operation. As no oil level checks or oil changes are required, the units are maintenance free. The operator also saves the cost of servicing and disposing of used oil. The use of high quality materials minimises wear and results in above average component life.
Our DC compressors meet all relevant railway standards
Our DC compressors are manufactured in Germany and meet all relevant standards and specifications for the railway sector. In addition, Dürr Technik has been IRIS certified since 2009.
- EN 50121-3-2 Electromagnetic compatibility
- EN 45545-2 Fire safety requirements
- EN ISO 9227 Salt spray test
- EN 61373 Vibration and shock
Deutsche Bahn AG certified: oil-free compressor D-120
Designed for rail vehicles to ensure maximum safety, reliability and economy. Manufacturers, operators and system suppliers in the railway sector use the oil-free D-120 compressor because of its compact design and reliable quality, e.g. for pantograph lifting. Suitable for retrofitting the LP115 compressor. Certified by Deutsche Bahn AG - Certificate No. 5245-2022-311.
