SCREW COMPRESSORS FOR THE RAILWAY INDUSTRY

BACK

Airpol SK series screw compressors are designed for operation on railway rolling stock to supply the traction vehicle’s pneumatic system as well as the entire train. Compressed air in railway vehicles is not only used to supply power to braking devices, but it is also used to supply air to other pneumatic devices that use air for their operation. These are e.g.: pneumatic sirens, sand traps, current collectors, electropneumatic contactors, sanitary equipment, doors, elements of mechanics of self-unloading units of freight wagons, etc.

SK screw compressors are manufactured for the railway industry with high quality standards to ensure the highest degree of safety and reliability of the device. Airpol has been designing and supplying components for traction vehicle pneumatic systems for years. Currently, Airpol’s offer includes both individual designs of new compressors and modernization of compressors that have been used in rolling stock for many years.
