This is the entry-level configuration in Castair's Industrial Series — but entry-level at Castair means a fully cast iron two-stage pump, not a cast iron-painted aluminum unit. If you are buying a shop compressor that you expect to run for 15-20 years without rebuilding the pump, this is the starting point.\u003c\/p\u003e\n\n\u003cp\u003eThe I513HC1-S uses the C1 pump (4-7.5HP rated, Inline 2 cylinder, two-stage) running at 767 RPM. The -S at the end indicates a factory-mounted magnetic motor starter is included — important if your shop requires starters for motor protection or code compliance. This is the 80-gallon horizontal version with single-phase power, making it accessible to shops that do not have 3-phase electrical service.\u003c\/p\u003e\n\n\u003cp\u003eThe -S with mounted starter distinguishes this from the base I513HC1 (which has the same compressor without the starter). If you know you need starter protection for your motor — and at 5HP single-phase, that is a reasonable requirement in many installations — this configuration saves you the trouble of sourcing and mounting one separately.\u003c\/p\u003e\n\n\u003ch2\u003eC1 Pump — Cast Iron Construction\u003c\/h2\u003e\n\n\u003ch3\u003ePump Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump designation:\u003c\/strong\u003e C1 — Two-stage, Inline 2 cylinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated HP range:\u003c\/strong\u003e 4-7.5HP — this pump is well within its operating range at 5HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump RPM:\u003c\/strong\u003e 767\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlywheel:\u003c\/strong\u003e 16.875-2B\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 cylinders, heads, valve plates, crankcase\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 for efficiency and low oil carry-over\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 with 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 and Electrical\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 (standard shop wiring)\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 Factory-mounted magnetic motor starter (-S designation)\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 with factory-mounted magnetic starter\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 C1 (Two-stage, Inline 2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump RPM:\u003c\/strong\u003e 767\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 48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 600 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 I513HC1-S compressor — fully assembled\u003c\/li\u003e\n\u003cli\u003eFactory-mounted magnetic motor starter (-S designation)\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\u003eAftercooler is available as an option (BGAC1M — 35 CFM, for 5, 7, 10HP models).
