Auxiliary Oilless Piston Compressor for Electric Trains and Locomotives

Compressor's function is to supply compressed air to rolling stock auxiliary devices and mechanisms (electric trains and locomotives), to pantograph lifters in particular.

Motor Supply Voltage: 50, 75, 110VDC.
Climatic Version У2 per GOST 15150-69.

Compressor Code:

Advantages:

Easy maintenance as the oilless design requires replacing air filter once a year;
Higher cold-start efficiency;
Long motor service life (6,000 eng h or 20–25 years of operation);
No oil disposal costs required which makes the compressor more ecofriendly.
