Oil-free air compressors are those which do not utilize oil for lubrication of components within the compressor. Instead, the system is designed in such a way that there is no mechanical contact between components. Water or special coatings can also be used for lubrication.
Air compressors which do not use oil for lubrication can offer many benefits over oil-lubricated versions, such as the elimination of oil leaks and reduced maintenance. However, there are also some drawbacks associated with oil-free air compressors such as higher upfront costs.
In this interview with Robert Horneman, Product Manager at ELGi Industrial – a developer of air compressors – he outlines how oil-free air compressors differ from their oil-lubricated counterparts and the various factors which need to be taken into account when selecting a compressor.
