There is no second set of tires, lights, bearings, or registrations to maintain, nothing to unhitch at the jobsite, and no separate unit to lose track of overnight. For electric co-ops, telecom contractors, and municipal water and wastewater fleets running Class 4 to 6 service bodies, the KDU's footprint and support-mount frame are the reason it gets specified as the default onboard air supply.\u003c\/p\u003e\u003ch3\u003eSpec sheet\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eConfiguration\u003c\/td\u003e\n\u003ctd\u003eUtility mount \/ support-mounted skid for truck deck mounting\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFree Air Delivery (FAD)\u003c\/td\u003e\n\u003ctd\u003e185 CFM @ 100 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax working pressure\u003c\/td\u003e\n\u003ctd\u003e125 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEngine\u003c\/td\u003e\n\u003ctd\u003eKubota V2403-CR, 4-cylinder liquid-cooled diesel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEmissions\u003c\/td\u003e\n\u003ctd\u003eEPA Tier 4 Final\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated horsepower\u003c\/td\u003e\n\u003ctd\u003e49 HP (ECU-limited)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAirend\u003c\/td\u003e\n\u003ctd\u003eCP C111, direct-driven (no gearbox)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAir outlets\u003c\/td\u003e\n\u003ctd\u003e2 x ¾\" NPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAir receiver\u003c\/td\u003e\n\u003ctd\u003e4.5 gallon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApproximate dry weight\u003c\/td\u003e\n\u003ctd\u003e~2,060 lbs (skid)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eController\u003c\/td\u003e\n\u003ctd\u003eCP XC2003 with 3.5\" diagnostic display\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCold start\u003c\/td\u003e\n\u003ctd\u003e400W 120V block heater standard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFiltration\u003c\/td\u003e\n\u003ctd\u003eHeavy-duty 2-stage air filter, centrifugal oil separator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat 185 CFM gets you\u003c\/h2\u003e\u003cp\u003e185 CFM is the most common contractor-owned CFM size in North America for good reason.

The C111 is coupled directly to the engine flywheel: no gearbox, no belts, no idler pulleys. In practice that means lower fuel consumption per CFM delivered, fewer wear items, and a quieter machine. Over a typical 2,000-hour annual duty cycle the direct-drive design commonly saves several hundred gallons of diesel against belt-driven competitors.\u003c\/p\u003e\u003ch2\u003eNeed a towable 185 instead?\u003c\/h2\u003e\u003cp\u003eIf your application requires a trailer with a DOT light package, 4-way plug, pintle hitch, and safety chains, this is not the right model.
