Kaeser MOBILAIR M27PE Towable Rotary Screw Air Compressor - 92 CFM, Diesel
The M27PE is the four-pressure machine in the small diesel class - 92 CFM at 100 psig, and still 57 CFM when you dial it to 200. That range is what makes it the rental-fleet workhorse: one unit covers general air tool work, sandblasting and higher-pressure jobs without a second machine on the trailer. Kaeser's anti-frost valve holds discharge temperature up so ambient moisture does not freeze in the tool, and the gear-driven SIGMA PROFILE airend turns slowly enough to keep fuel burn down.

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.
