The defining feature of this unit compared to the C1-based models is the pump: the C2 runs at 420 RPM — well below the 767 RPM of the C1 — which translates to meaningfully quieter operation, less heat generated per hour of runtime, and longer pump service life between valve and ring service.\u003c\/p\u003e\n\n\u003cp\u003eThe performance output is the same as the C1 versions: 22.0 CFM free air, 17.5 CFM at 175 PSI. You are not buying more CFM when you choose the C2 — you are buying quieter operation and longer pump life. For shops where the compressor is in or near the work area, the noise difference is significant. For shops that run the compressor hard all day, the slower RPM means less wear accumulating per hour.\u003c\/p\u003e\n\n\u003cp\u003eThe C2 pump is a Two-stage, V4 cylinder design — four cylinders versus the C1's Inline 2. The V4 arrangement runs smoother and with less vibration than an inline twin, which is another reason the C2 is the premium choice at 5HP.\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 — this pump is running below its rated range at 5HP, which means additional longevity headroom\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 — 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 on every cycle\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\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 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 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-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 available as factory option (BGAC1M — 35 CFM, for 5-10HP models).

The 420 RPM C2 runs about 45% slower than the 767 RPM C1 — at equal runtime hours, the C2 pump accumulates significantly less wear. If you are buying this compressor expecting to run it for 15-20 years, the C2 pump investment typically pays back in reduced maintenance and extended pump life.\u003c\/p\u003e\n\n\u003ch2\u003eWhen Does a Shop Need This?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1-2 technician shop on single-phase power that values quieter compressor operation\u003c\/li\u003e\n\u003cli\u003eShop where the compressor is in or near the work area and noise level matters to technicians or customers\u003c\/li\u003e\n\u003cli\u003eHigh-runtime applications (8+ hours per day) where slower pump RPM meaningfully extends service intervals\u003c\/li\u003e\n\u003cli\u003eYou want factory-mounted motor protection built into the unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy Buy From Air Compressor Factory Direct?\u003c\/h2\u003e\n\u003cp\u003eSince 2016, we have sold industrial air compressors to shops and facilities that need real equipment.
