This is the quieter, slower-running 5HP option in Castair's horizontal lineup: 420 RPM versus the 767 RPM of the C1-equipped models, with identical output of 17.5 CFM at 175 PSI.\u003c\/p\u003e\n\n\u003cp\u003eThe C2 is a Two-stage, V4 cylinder pump rated for 7.5-10HP applications. Running it at 5HP means the pump is operating well within its rated capacity, which shows up in longer service intervals and quieter operation. The trade-off is weight: the C2 adds 100 lbs over the C1 configuration — 700 lbs versus 600 lbs — and the horizontal dimensions change slightly at 64 x 20 x 46 versus 64 x 20 x 48 inches.\u003c\/p\u003e\n\n\u003cp\u003eThis is the base unit — no factory-mounted motor starter. If you have panel-mounted motor protection or a licensed electrician handling the installation with proper overcurrent protection, the base unit is the clean choice. If you want a self-contained unit with the starter already mounted, choose the I513HC2-S.\u003c\/p\u003e\n\n\u003ch2\u003eC2 Pump — Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump designation:\u003c\/strong\u003e C2 — Two-stage, V4 cylinder configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated HP range:\u003c\/strong\u003e 7.5-10HP (running at 5HP means additional service life margin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump RPM:\u003c\/strong\u003e 420\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlywheel:\u003c\/strong\u003e 19.0-2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil capacity:\u003c\/strong\u003e 2 quarts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e 100% cast iron throughout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearings:\u003c\/strong\u003e Tapered roller bearings at both crankshaft ends\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnecting rods:\u003c\/strong\u003e Precision steel with automotive-type rod insert bearings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValves:\u003c\/strong\u003e Disc and spring — field-replaceable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePistons:\u003c\/strong\u003e 4-ring configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnloader:\u003c\/strong\u003e Centrifugal — loadless start-up every time\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTank and Frame\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank capacity:\u003c\/strong\u003e 80 gallons, horizontal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank construction:\u003c\/strong\u003e Powder-coated ASME-rated steel, channel saddle frame\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety valve:\u003c\/strong\u003e ASME-rated, factory installed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt guard:\u003c\/strong\u003e Totally enclosed metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDischarge lines:\u003c\/strong\u003e Copper tubing or stainless braided flex line\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eMotor\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower:\u003c\/strong\u003e 5HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase:\u003c\/strong\u003e Single-phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor speed:\u003c\/strong\u003e 1725 RPM industrial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService factor:\u003c\/strong\u003e 15% minimum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor starter:\u003c\/strong\u003e Not included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax working pressure:\u003c\/strong\u003e 175 PSI\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003ePerformance Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor output:\u003c\/strong\u003e 5 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical:\u003c\/strong\u003e Single-phase (no starter included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank capacity:\u003c\/strong\u003e 80 gallons, horizontal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump:\u003c\/strong\u003e C2 (Two-stage, V4)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump RPM:\u003c\/strong\u003e 420\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree air delivery (0 PSI):\u003c\/strong\u003e 22.0 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDelivery at 175 PSI:\u003c\/strong\u003e 17.5 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax pressure:\u003c\/strong\u003e 175 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (LxWxH):\u003c\/strong\u003e 64 x 20 x 46 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 700 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCastair I513HC2 compressor — fully assembled base unit\u003c\/li\u003e\n\u003cli\u003eASME safety valve (factory installed)\u003c\/li\u003e\n\u003cli\u003ePressure switch with unloader\u003c\/li\u003e\n\u003cli\u003eTotally enclosed metal belt guard\u003c\/li\u003e\n\u003cli\u003eCopper discharge and unloader tubing (or stainless braided flex line)\u003c\/li\u003e\n\u003cli\u003eOwner's documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eMagnetic motor starter NOT included.
