Air Reciprocating Compressors are generally installed on trains to activate the braking system and the automatic doors in the carriages.

In railway transport, reciprocating compressors are needed to activate the Air braking system or the Air system of the doors in the carriages. The market trend is for high speed and fully oil-free reciprocating compressors.

Dott. Ing. Mario Cozzani s.r.l. designed specific valves for this application in order to guarantee excellent reliability with oil-free compressor working up to 1800 rpm, low noise and extreme environmental conditions.

Thanks to its specific knowledge in designing and manufacturing cylinder valves since 1946, it has been able to meet all the special requirements requested by this specific market.
