The 185 KDU delivers that capability with the lowest fuel-per-CFM rating in its class.\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\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, 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 @ 2,700 RPM (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\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\u003eFuel capacity\u003c\/td\u003e\n\u003ctd\u003e25 US gallons\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRuntime at full load\u003c\/td\u003e\n\u003ctd\u003e8+ hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCold start (standard)\u003c\/td\u003e\n\u003ctd\u003e14°F (lower with starting aid)\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\u003eCooling\u003c\/td\u003e\n\u003ctd\u003eSide-by-side aluminum coolers\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\u003eBuilt for utility crews and line trucks\u003c\/h2\u003e\u003cp\u003eThe 185 KDU's footprint and skid layout make it a natural fit on Class 4-6 utility bodies — which is why so many electric co-ops, telecom contractors, and municipal water\/wastewater fleets spec it as their default truck-mounted air supply.

Chicago Pneumatic's C111 airend is coupled directly to the engine flywheel — no gearbox, no belts, no idler pulleys. The practical impact: lower fuel consumption per CFM delivered, fewer wear items, and a quieter machine. Over a typical 2,000-hour annual usage cycle, the direct-drive design typically saves operators several hundred gallons of diesel versus belt-driven competitors.\u003c\/p\u003e\u003ch2\u003eController and diagnostics\u003c\/h2\u003e\u003cp\u003eThe CP XC2003 controller is the same panel used on the larger 250 and 400-150 models — a 3.5-inch diagnostic display with operating-hour logging, real-time pressure and temperature readouts, fault history, and automatic shutdown for over-temperature, low oil pressure, and low fuel.
