Kaeser MOBILAIR M58 Utility Rotary Screw Air Compressor - 210 CFM, Diesel
The M58 Utility is the narrow one - 33 inches wide, 85 long, direct drive, built to live permanently on a service truck or in a utility body rather than behind a hitch. It still puts out 210 CFM, more than the towable M55PE, off a 28-gallon tank. Sandblast check valve is standard equipment on this model rather than an option.

Every MOBILAIR shares the same core engineering. The large, slow-turning SIGMA PROFILE® airend delivers 15–20% more air per gallon of fuel than comparable units, which is the single biggest line item over a machine's life. The anti-frost valve holds discharge air temperature high enough that ambient moisture will not freeze in the tool, protecting air motors and extending tool service life. Heavy-duty chassis and canopy resist corrosion; package airflow is routed to keep the engine cool under load; and the cold-start battery means the unit turns over in winter. Towable models ride on torsion bar suspension with even weight distribution.
