Description
The Kaeser Mobilair M55 and M59 are towable 185-195 CFM-class diesel rotary-screw air compressors built around Kaeser's SIGMA PROFILE airend for more air per gallon. The mid-size construction-site workhorse for civil, demolition, and pipeline crews running three to four pneumatic tools simultaneously on a single mobile circuit with surge headroom.
- M55PE delivers 185 CFM at 100 PSI from a 43 hp Kubota D1803CR-T diesel, EPA Tier 4 Final certified
- M59 is the next-step variant in the same family for slightly higher airflow or updated emissions compliance same chassis architecture and SIGMA PROFILE airend
- Direct-drive single-stage oil-injected rotary-screw construction; Kaeser SIGMA PROFILE rotor geometry more air per gallon than competing 185-200 CFM screws
- Heavy-duty steel chassis with 15 in. wheels, rigid tow bar, pintle-eye towing standard, galvanized canopy designed for outdoor jobsite life
- Extended service intervals over competing 185-200 CFM diesel screws; fuel-tank capacity sized for full-shift; on-board lockable tool box
- Applications: civil-construction multi-tool circuits, demolition paving breakers and rivet busters, pipeline and utility-trenching rock drills, moderate-scale sandblasting, rental fleets
- 185-195 CFM sweet spot for two to four 50-CFM-class tools simultaneously with surge headroom; replaces legacy 185-200 CFM piston and screw compressors
- Standard CGA air outlets compatible with crowsfoot, claw, and quick-disconnect; Crowder Supply stocks contractor air hose, line oilers, hose whips, regulators, aftercoolers, Kaeser service parts
