It delivers \u003cstrong\u003e31 CFM\u003c\/strong\u003e and builds to a \u003cstrong\u003e175 PSI\u003c\/strong\u003e maximum, with 26 CFM still on tap at full 175 PSI pressure — enough to keep impact tools, sanders, and spray equipment moving without the pump cycling constantly.\u003c\/p\u003e\n\u003cp\u003eWhat sets this unit apart is the Silent Air patented noise-suppression system. Instead of an enclosed cabinet that drives up cost and blocks service access, EMAX silences the loudest source of compressor noise — the air intake — with a serviceable silencer, noise-reducing baffle plates, and high-capacity filter media. The result runs up to \u003cstrong\u003e50% quieter\u003c\/strong\u003e, at or below normal conversational volume, while every component stays out in the open for routine maintenance.\u003c\/p\u003e\n\u003cp\u003ePower comes from a 7.5 HP open drip-proof (ODP) motor wired for \u003cstrong\u003e230V single-phase\u003c\/strong\u003e service, paired with a magnetic starter so the unit drops onto common shop power without a phase converter. The pump is rated for \u003cstrong\u003econtinuous-run operation\u003c\/strong\u003e at a 60% duty cycle, and EMAX estimates 70,000 hours of pump life under proper maintenance.\u003c\/p\u003e\n\u003cstyle\u003e.embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }\u003c\/style\u003e\n\u003cdiv class=\"embed-container\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/atakh7WsbDY\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003ch3\u003ePressure-Lubricated Cast Iron Pump\u003c\/h3\u003e\n\u003cp\u003eUnlike splash-lubricated compressors, the ESP07V120V1 uses a gear-driven oil pump mounted to the rear of the crankshaft that pushes a continuous flow of oil to every bearing point. The crankshaft and connecting rods are rifle-drilled for direct oil delivery to high-friction wear points, an automotive-style spin-on oil filter keeps the oil clean, and a liquid-filled gauge lets the operator read oil pressure at a glance.
