Customized & Eco-friendly
Requirement-oriented configuration of the compressors and systems through a broad product range and extensive special equipment
Oil-free compressors protect the environment by saving crude oil and avoiding oil and oil-filter as hazardous waste.
Compact design and low weight due to omission of condensate collector and oil filter
Increased driving comfort thanks to noise and vibration-reducing dampers and spring elements
Operating the signal horn
Control of toilet doors and emptying of the toilet bowl
Wheel flange lubrication
Air brake system
Each train has its own special features with specific requirements. Therefore, our product range offers you all options - from the proven main air compressor with belt drive to the technical high-end solution.
Some railway vehicles, such as trams, use a hydraulic brake instead of a pneumatic one. For this reason, smaller auxiliary air compressors are required for all pneumatic applications such as sanding or wheel flange lubrication.
