It delivers \u003cstrong\u003e38 CFM\u003c\/strong\u003e (34 CFM at its 175 PSI maximum) and runs on \u003cstrong\u003e230V single-phase power\u003c\/strong\u003e (±10%), so it does not require three-phase service. A magnetic starter, dual-bolt belt tensioner, electric auto tank drain, and isolator pads are part of the package.\u003c\/p\u003e\n\u003cp\u003eThis is a Silent Air model: EMAX's patented noise-suppression system runs \u003cstrong\u003eup to 50% quieter\u003c\/strong\u003e than comparable compressors, holding noise at or near conversational volume. Unlike enclosed cabinet designs, the silencer doesn't restrict service access — the intake system pairs noise-reducing baffle plates with high-capacity filter media that EMAX rates at up to 1000% more filtration than standard setups.\u003c\/p\u003e\n\u003cp\u003eThe pressure-lubricated, 100% cast iron pump (model APP4V1043TP) carries an \u003cstrong\u003eestimated 70,000-hour pump life\u003c\/strong\u003e, and the unit is \u003cstrong\u003eETL, ASME, and CRN certified\u003c\/strong\u003e.

Unlike splash-lubricated systems, pressure lubrication puts oil precisely where it's needed in high-stress, continuous-duty operation. An automotive-style \u003cstrong\u003espin-on oil filter\u003c\/strong\u003e keeps the oil clean between changes, and a liquid-filled gauge with an adjustable regulator lets you monitor and set oil pressure accurately.\u003c\/p\u003e\n\u003cfigure\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0771\/5550\/0318\/files\/emax-esp10v120v1pk-10-hp-120-gallon-air-compressor-feature-4.jpg?v=1781269578\" alt=\"Numbered diagram of oil pump assembly with liquid-filled oil pressure gauge\"\u003e\n\u003cfigcaption\u003eOil pump: bleeder valve, liquid-filled gauge, gear pump, regulator, spin-on filter\u003c\/figcaption\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e100% Cast Iron Pump\u003c\/h3\u003e\n\u003cp\u003eThe crankcase, cylinders, cylinder heads, crankshaft, connecting rods, and high-pressure piston are all cast iron — no aluminum sleeves under the paint.

When tank pressure reaches the preset maximum, the pilot valve unloads the compressor — holding the intake valve open so the motor keeps running instead of repeatedly starting under load. That cuts amp draw by up to 60% while unloaded, circulates cool air through the cylinders, and protects the motor and magnetic starter from start-stop wear. For duty cycles over 40%, a ball valve connected to the pilot valve can be opened for continuous-run operation.\u003c\/p\u003e\n\u003ch3\u003eHeavy Cast Iron Flywheel and Belt Drive\u003c\/h3\u003e\n\u003cp\u003eThe 10 HP pump runs a \u003cstrong\u003e20-inch cast iron flywheel with two B-style groove belts\u003c\/strong\u003e and nine large cooling fins. The flywheel's mass builds kinetic energy that reduces amp draw, while the multi-belt B-width drive provides more grip surface at lower belt tension than narrow single A-width belts — less strain on motor and pump bearings, less noise, and longer belt life.
