It is built for shops and light-industrial operations that run air tools, plasma cutters, sandblasters, or production equipment long enough that a piston compressor would overheat — the oil-injected rotary screw air end is rated for \u003cstrong\u003e100% duty cycle\u003c\/strong\u003e, so it can run continuously without a forced cool-down period.\u003c\/p\u003e\n\u003cp\u003eAt its core is a single-stage, oil-injected rotary screw air end built around a male-and-female rotor design with an estimated \u003cstrong\u003e100,000-hour\u003c\/strong\u003e service life. Air moves through an air\/oil separator and an air-cooled aftercooler before it reaches the tank, pulling out heat and moisture along the way. Power reaches the air end through a two-belt V-belt drive that uses wider B- and C-width belts to spread the load over more surface area, lower belt tension, and cut noise and vibration — the 7.5 HP unit runs at about \u003cstrong\u003e62 dB(A)\u003c\/strong\u003e. The totally enclosed, fan-cooled (TEFC) motor turns at 1750 RPM and draws 10.4 full-load amps, including a 1.15 service factor, on a 460V three-phase circuit.\u003c\/p\u003e\n\u003cp\u003eAn onboard digital control panel runs the compressor and shows operating pressure and temperature, with start, stop, and emergency-stop controls and six built-in maintenance notifications that flag when it is time to service filters, oil, and other wear items. The motor and cabinet are \u003cstrong\u003eVSD-ready\u003c\/strong\u003e — a variable-speed drive can be added later through EMAX if your air demand swings widely.\u003c\/p\u003e\n\u003cp\u003eCompressed air then passes through the integrated refrigerated dryer before it reaches your lines, where a condenser and cooling fan pull moisture out of the air stream so tools, dies, and finishes stay dry. The package is mounted on a \u003cstrong\u003ematte-black 120-gallon horizontal receiver tank\u003c\/strong\u003e, plumbed with braided hydraulic hoses, and fitted with a dual-timer electric automatic tank drain that expels condensate on a schedule you set — anywhere from 1 to 45 minutes — with an air muffler for quiet discharge.\u003c\/p\u003e\n\u003cfigure\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0771\/5550\/0318\/files\/emax-ervk070003-460-rotary-screw-air-compressor-dryer-base.jpg?v=1781778673\" alt=\"Matte black 120-gallon horizontal receiver tank on welded mounting feet with braided hydraulic hose and brass valve\"\u003e\n\u003cfigcaption\u003eMatte-black horizontal receiver tank with braided hose and brass ball valve.\u003c\/figcaption\u003e\n\u003c\/figure\u003e\n\u003cp\u003eA swing-arm dryer mount lets the dryer hinge away from the compressor cabinet, opening up room to reach filters, belts, and the air end during service without unbolting the dryer.\u003c\/p\u003e\n\u003cp\u003eThis unit ships by freight and requires a \u003cstrong\u003e460V three-phase\u003c\/strong\u003e circuit on a dedicated line — confirm your shop's service before ordering.

The integrated refrigerated dryer carries its own \u003cstrong\u003e1-year standard warranty\u003c\/strong\u003e on parts, workmanship, and labor.\u003c\/p\u003e\n\u003cp\u003eBoth can be extended. Enrolling in EMAX's scheduled-maintenance program — changing oil and filters on the published schedule using EMAX SMART OIL — extends the compressor to up to \u003cstrong\u003e10 years on the rotary screw pump and the three-phase motor\u003c\/strong\u003e and 5 years on the remaining components, and extends the dryer to \u003cstrong\u003e3 years\u003c\/strong\u003e.
