Kaeser – other models: towable compressors from the German manufacturer on car-trailer chassis outside the named ranges, M range and Mobilair from 0.54 to 2.75 t
Kaeser Kompressoren of Coburg, alongside stationary units, also builds towable compressors mounted on trailer chassis for mobile use on building sites. This page gathers the models outside the named ranges, mainly the M range (M36 to M135) and the versions marketed as "Mobilair"; "PE" denotes variants with Kaeser's Sigma-profile screw compressor block. The three-digit model number at Kaeser usually corresponds to delivery volume in cubic metres per minute.

The register lists here 59 versions with unladen weights from 535 to 2,750 kg, gross vehicle weights from 750 to 2,750 kg, lengths from 2,317 to 5,060 mm and widths from 1,300 to 2,075 mm.
Trailer compressors of this size work on building sites, in road and civil engineering, and at plant-hire firms, supplying pneumatic hammers, sandblasting equipment or pneumatic tools without the need for a separate vehicle with a built-in compressor. Kaeser competes there with Atlas Copco and Compair, which offer comparable trailer compressors.
When buying used, the operating hours of the compressor block matter, along with the condition of the oil cooler and intake filter, the tightness of the air hoses and valves, the condition of the chassis, axle and drawbar, and a valid trailer inspection. Wear parts such as filters, oil separators and belts are available through Kaeser's service network and independent compressed-air specialists.
