This is a shop compressor built for continuous heavy-duty use — the kind of unit that runs all day in a diesel bay, body shop, or fleet maintenance facility without issues. The tandem configuration means two cast iron pumps operating off a single motor, sharing the workload and delivering more total air output than a single-pump 10 HP unit while maintaining the continuous duty rating your shop demands.\u003c\/p\u003e\n\n\u003cp\u003eSingle-phase power is a significant factor in compressor selection for many shops — three-phase infrastructure requires electrical upgrades that add cost and lead time. The T10112HC1-S delivers 10 HP of compressor capacity on standard single-phase power, making it the practical choice for shops with single-phase electrical service that need serious air output.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e T10112HC1-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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStage:\u003c\/strong\u003e Two-stage compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePump RPM:\u003c\/strong\u003e 767 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTank:\u003c\/strong\u003e 120-gallon horizontal, ASME-certified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions (LxWxH):\u003c\/strong\u003e 85 x 28 x 57 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1,115 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 $6,560.05\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCast Iron Pump Construction — Why It Matters\u003c\/h3\u003e\n\u003cp\u003eCastair has been building compressors since 1991 with one core principle: cast iron pumps, not aluminum. Cast Air pumps are oil-lubricated, not oil-less, and run at very slow RPMs. This combination means quieter operation, better heat dissipation, and a service life measured in decades rather than years.
