It runs on 460V 3-phase power. This is a proven continuous-duty machine: if your shop is running sanders, spray equipment, impact tools, and tire equipment through a full shift, 40 CFM at 100 PSI from a rotary screw is what keeps tools performing without pressure drop.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eNote on tank size: The model number suffix \"-VP75\" suggests a 75-gallon tank designation, but the confirmed product listing specifies an 80-gallon vertical tank. The 230V version (R1038VP75-230) is listed at 75 gallons. Verify current specifications with us at 866-217-0063 before ordering if tank volume is a deciding factor.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003ePerformance Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor output:\u003c\/strong\u003e 10 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhases:\u003c\/strong\u003e 3-phase\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 460V (for 460V or 480V 3-phase service)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCFM output:\u003c\/strong\u003e 40 CFM at 100 PSI — confirmed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTank volume:\u003c\/strong\u003e 80 gallons, vertical orientation — confirmed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuty cycle:\u003c\/strong\u003e 100% continuous (rotary screw)\u003c\/li\u003e\n  \u003cli\u003e\u003cem\u003eAdditional specs (max PSI, dimensions, weight, oil capacity) — contact us to confirm\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat 40 CFM at 100 PSI Means in a Working Shop\u003c\/h3\u003e\n\u003cp\u003eCFM is the number that actually determines whether your compressor can keep up.

The same motor at 230V draws approximately 28-32 amps. Half the amperage means smaller wire gauge, smaller breaker, and less heat in your electrical infrastructure.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLess voltage drop over distance\u003c\/strong\u003e — Lower amperage through the same wire gauge produces less voltage drop. If your compressor is more than 30-50 feet from the panel, 460V is significantly more efficient and the motor runs closer to its rated voltage under load.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCooler running under sustained load\u003c\/strong\u003e — Lower amperage translates to less resistive heat in the wiring and motor windings.
