Auxiliary air
Oil-free auxiliary air compressors from Dürr Technik
Versatile on the move in rail transport
Are you looking for suitable compressors for special applications on your rail vehicles? Whether as a unit or system solution - with an auxiliary air compressor from Dürr Technik, you are always in good hands, because we understand exactly the requirements of our customers. After all, we are the world market leader in this field.
Durability, cost efficiency and certification are key factors in the rail sector. But also the weight of the individual components plays an important role - because rail wear costs can be significantly reduced as a result. With the lightest oil-free compressor for pantographs currently available, Dürr Technik is contributing to further weight reduction in the railway sector.
Aggregates, special aggregates and system solutions
A large number of variants are available - from DC to 3-phase solutions, from 24V DC to 400V 3~AC. As special aggregates, our products may be equipped with EMC filters, special lacquers, special electronics, connectors, etc. You can rely on our unique competence in the development and manufacture of complete compressed air systems and facilities as customized system solutions according to your specifications.
