The Kaeser Mobilair M27 Utility and M30 Utility are skid-mount diesel rotary-screw air compressors each a self-contained compressed air skid delivering 92 and 100 CFM at 100 PSI from a powder-coated steel cabinet that bolts directly to a service-truck deck. They pair a 21 hp Kubota D1105-B three-cylinder diesel with Kaeser’s SIGMA PROFILE airend the same running gear as the towable versions, repackaged for fleets that can’t pull a trailer.

One machine feeds two 3/4 in. NPT outlets, so a deck-mounted unit can run a breaker and a chipping hammer at once, and the M27’s variable settings reach 200 PSI for pressure work. If towing is an option, the same airend rides a single-axle trailer as the Mobilair M27/M30 portable; both live in our diesel-driven air compressor range. Standard Kaeser anti-frost control keeps tools cycling through sub-freezing shifts.

Mobilair M27/M30 Utility FAQ

What separates the M27 Utility from the M30 Utility?
Output: the M27 Utility delivers 92 CFM at 100 PSI with variable settings up to 200 PSI, while the M30 Utility delivers 100 CFM at 100 PSI. Both share the 21 hp Kubota D1105-B diesel and the same bolt-down cabinet.

How is the Utility version different from the towable M27/M30?
Same SIGMA PROFILE airend and Kubota engine, repackaged in a powder-coated steel cabinet that bolts to a truck deck or skid instead of riding a trailer — the answer for fleets that cannot tow.

How many tools will it feed?
Two 3/4 in. NPT outlets let one deck-mounted unit run a paving breaker and a chipping hammer at the same time.

Is there a warranty on the airend?
An optional 5-year Kaeser air-end warranty is available, and Crowder Supply stocks Genuine Kaeser service parts in Denver.
