The Kaeser Mobilair M27 and M30 are single-axle towable diesel rotary-screw air compressors delivering 92 and 100 CFM at 100 PSI the modern replacement for piston wheelbarrow compressors. A 21 hp Kubota D1105-B three-cylinder diesel drives Kaeser’s SIGMA PROFILE airend inside a rotomolded polyethylene cabinet, and the M27’s variable pressure settings reach 200 PSI (57 CFM) for pressure-testing and cable work.

Standard anti-frost control pre-conditions the air so chipping hammers and breakers keep cycling below freezing, and dual 3/4 in. NPT outlets run two tools at once a 60 lb breaker plus a second tool, or a pneumatic post driver on fence and sign work. Fleets that can’t tow will find the same airend deck-mounted in the M27/M30 Utility; keep every tool oiled with an in-line lubricator at the whip.

Kaeser M27 / M30 FAQ

What is the difference between the M27 and the M30?
The M30 delivers a fixed 100 CFM at 100 PSI. The M27 delivers 92 CFM at 100 PSI but adds variable pressure settings 74, 67 and 57 CFM at 145, 175 and 200 PSI for pressure-testing and cable work. Both sit in our diesel-driven air compressor range.

How many tools can it run at once?
Dual 3/4 in. NPT outlets support two-tool operation: two 40 CFM tools, a 60 lb breaker plus a chipping hammer, or a single 90 CFM blast pot.

Will pneumatic tools ice up in freezing weather?
Kaesers standard anti-frost control pre-conditions the air supply to prevent ice formation in pneumatic tools during sub-freezing operation.

What warranty and parts support do these compressors carry?
An optional 5-year Kaeser air-end warranty is available, and Crowder Supply stocks Genuine Kaeser service parts in Denver.
