Welcome to the website of the Ecodesign Preparatory Study on Compressors (ENER Lot 31). This website presents the results of two studies on compressor packages driven by electric motors, in the context of Article 15 of the Directive 2009/125/EC on Ecodesign and the Ecodesign Working Plan(s).

The most recent study covered low pressure and oil-free compressor packages. This study started on 14 April 2015 and was finalized on 7 June 2017.

Lubricated/oil-injected compressor packages are referred to as "standard air" and were addressed in a preceding study (start 6 March 2012, finalized 6 June 2014).

The final reports of both studies are available on this website, in the Documents section.

The authors wish to thank all who have contributed to and/or commented on reports and meetings in the context of this study, in particular the experts that provided valuable information and guidance.

Kind regards,

Martijn van Elburg
