Kaeser Air Compressors

Kaeser operates world-wide company, providing a broad range of air compressor technology to users around the globe. Kaeser air compressors are typically not considered a DIY type of air compressor manufacturer.

Kaeser has a professional service group that, I expect, provides a very high level of after sales service expected of a compressor company of their caliber.

Kaeser Compressor USA asks that I provide some information for Kaeser air compressor users, posted below the photo. I am pleased to provide it for you.
