Features and benefits

Atlas Copco's oil-free Scroll compressor offers Mobility operators the clean energy that they are looking for. An oil-free design means the need to store and handle a huge stock of oil is eliminated as well as the chances of over or underfilling the compressors during maintenance, leading to expensive repairs. Costs associated with collecting and treating the condensate is also eliminated, leading to cheaper overall maintenance costs for the end user.

Featuring less moving parts than an equivalent reciprocating oil-free compressor, the scroll compressor allows even cheaper running costs.

Thanks to its orbiting design the scroll compressor also provides lower noise and vibration levels than equivalent reciprocating compressors. Making it suitable for Railway and Mobility applications where low noise levels are a must.

We integrate this compressor into Air Generation and Treatment Units according to your specific needs with convenient maintenance accesses in compact and easy to install packages, compliant with your environmental conditions.
