At 420 RPM, these are the quietest cast iron pumps Castair builds. Paired with 240 gallons of air storage, this unit handles the most demanding single-phase shop applications: continuous spray operations, high-duty-cycle blast equipment, body shops running multiple tools simultaneously, and any operation that needs both maximum quiet operation and maximum air reserve from a single-phase power source.\u003c\/p\u003e\n\n\u003cp\u003eThis is not an entry-level purchase — at $9,012.30, the T10124HC2-S is a long-term infrastructure investment. The 420 RPM pump speed means these pump assemblies are physically larger and heavier than C1 units, which accounts for the 1,655 lb weight. If you are going to run this compressor for 20 years — which is entirely achievable with cast iron pumps at this speed — the investment makes sense.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e T10124HC2-S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower:\u003c\/strong\u003e 10 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase:\u003c\/strong\u003e Single-phase (1-phase)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Tandem — 2 pumps, 1 motor, two-stage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePump RPM:\u003c\/strong\u003e 420 RPM (slowest configuration in the 10 HP tandem range)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTank:\u003c\/strong\u003e 240-gallon horizontal, ASME-certified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions (LxWxH):\u003c\/strong\u003e 85 x 30 x 64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1,655 lbs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Speed:\u003c\/strong\u003e 1,725 RPM industrial with 15% service factor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrice:\u003c\/strong\u003e $9,012.30\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCast Iron Pump Construction\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAll cast iron:\u003c\/strong\u003e Cylinders, heads, crankcase, and valve plates — cast iron throughout for heat dissipation and long service life\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSlow RPM operation:\u003c\/strong\u003e Lower speed means less heat, less noise, and longer life between rebuilds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered roller bearings:\u003c\/strong\u003e Both ends of each crankshaft for superior support and reduced friction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision steel connecting rods:\u003c\/strong\u003e Automotive-type rod insert bearings at crankshaft and wrist pin for long service life\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc and spring valves:\u003c\/strong\u003e Stainless steel — approximately 10x the service life of standard reed valves, easy to service in the field\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4-ring pistons:\u003c\/strong\u003e Better sealing, higher compression efficiency, less oil carry-over\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentrifugal unloader:\u003c\/strong\u003e Load-free startup every time — the motor never has to start against tank pressure\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTank, Motor, and Controls\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePowder-coated ASME-certified horizontal tank\u003c\/strong\u003e with channel base\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eASME safety valves\u003c\/strong\u003e — code-compliant pressure relief installed\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eTotally enclosed metal belt guard\u003c\/strong\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eCopper discharge and unloader tubes\u003c\/strong\u003e\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeavy-duty 1,725 RPM industrial motor\u003c\/strong\u003e with 15% service factor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMagnetic motor starter:\u003c\/strong\u003e Mounted and wired from the factory (S designation)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eComplete tandem compressor assembly (pumps, tank, motor, controls)\u003c\/li\u003e\n  \u003cli\u003eMagnetic motor starter — factory mounted and wired\u003c\/li\u003e\n  \u003cli\u003eCast Air \"Right from the Start\" Kit\u003c\/li\u003e\n  \u003cli\u003eASME safety valve(s)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy a Tandem vs. a Single-Pump Compressor\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigher combined CFM output:\u003c\/strong\u003e Two pumps filling the tank simultaneously means faster recovery under continuous demand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRedundancy:\u003c\/strong\u003e If one pump needs service, the other keeps running — a single-pump unit is either all or nothing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLower heat per pump:\u003c\/strong\u003e Neither pump runs at maximum stress — cooler operation extends pump life significantly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDoubled pump service intervals:\u003c\/strong\u003e Runtime hours split between two pumps means each pump sees half the cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eShipping and Lead Time\u003c\/h3\u003e\n\u003cp\u003eThese units ship within two weeks of order placement.
