EMAX Industrial Plus 10 HP 80-Gallon Two-Stage Silent Air Compressor with 58 CFM Refrigerated Dryer, Single-Phase, ESP10V080V1PK

Description

The EMAX Industrial Plus ESP10V080V1PK is a 10 HP two-stage piston air compressor on an 80-gallon vertical tank, packaged with a 58 CFM refrigerated air dryer as a complete air system. The pressure-lubricated V4 pump delivers 38 CFM (34 CFM at the maximum 175 PSI) on 230V single-phase power, so a shop without three-phase service can still run a full complement of air tools, spray equipment, or a blast cabinet from one machine. EMAX rates the pump for an estimated 70,000 hours of service life, backed by ETL, ASME, and CRN certifications.

This is a Silent Air model. EMAX’s patented noise-suppression system targets intake noise — the loudest source of compressor sound — with noise-reducing baffle plates and high-capacity filter media that provides up to 1000% more filtration than standard setups. The result is up to 50% quieter operation, with noise at or below conversational volume (each 10 dBA drop reads as a 50% reduction to the human ear). Unlike enclosed cabinet systems, which are costly and restrict service access, the silencer design stays easy to service without compromising accessibility.

The pump is built for duty, not just peak numbers: a gear-driven oil pump pressure-feeds every bearing point, the crankshaft and connecting rods are rifle-drilled for direct oil flow to high-friction components, and an automotive-style spin-on oil filter keeps the oil clean between changes. A liquid-filled gauge lets you monitor oil pressure at a glance. Rated for a 60% duty cycle, the unit also supports continuous-run operation through its head unloader system — at maximum tank pressure the pilot valve unloads the compressor so the motor keeps running instead of repeatedly starting under load, cutting amp draw by up to 60% while unloaded.

Features

Pressure-Lubricated Pump

A gear-driven automotive-style oil pump mounted to the rear of the crankshaft generates positive oil pressure, feeding the internal crankshaft bearings and upper connecting rod assembly. Unlike splash-lubricated systems, pressure lubrication delivers oil precisely where it’s needed — reducing friction, wear, and heat in high-stress, continuous-duty operation. The system includes an oil pump bleeder valve for quick priming, an adjustable regulator for precise oil pressure across RPM ranges, a liquid-filled oil pressure gauge, and a spin-on oil filter for simple oil changes.

100% Cast Iron Pump

All major pump components are cast iron — crankcase, cylinder heads, cylinders, connecting rods, crankshaft, and high-pressure piston. No aluminum sleeves under the paint: cast iron handles high-duty-cycle compression where aluminum components lose rigidity. The low-pressure pistons in the two-stage design are aluminum by design, operating under low stress around 45 PSI where the lighter material aids balance and efficiency.

Pistons and Connecting Rods

Cast iron high-pressure pistons withstand heavy loads and prevent cylinder scoring. The CNC-machined solid cast iron connecting rods carry replaceable bearing inserts and wrist pins, so the rod assembly is fully rebuildable rather than throw-away. A rifle-drilled oil port routes oil from the crankshaft through the rod to the piston pin and bearing for continuous lubrication.

The four-ring piston design uses precision-engineered overlap rings — two oil control rings remove excess oil on the downstroke while two compression rings seal under compression to prevent blow-by. The configuration maximizes sealing, reduces oil carryover, and extends ring life. Non-oil-absorbent gaskets minimize leakage and maintenance.

CNC-Machined Disc Valves

The concentric ring (disc) valves are precision surface-ground for sealing and durability — a more reliable design than the feather or fixed reed valves common in this class. Service takes minutes: remove the retainer, lift out the valve for inspection, and reinstall.

Cast Iron Cylinder Heads

Solid cast iron heads avoid the head gasket failures that aluminum heads are prone to. Tapped holes provide superior fastener strength, the casting maintains rigidity under demanding conditions, and the disc valve design holds a secure head gasket seal without retorquing.

Cylinder Construction

The cast iron cylinders are CNC-machined for flatness and precise tolerances, with a precision-honed bore that promotes easier break-in, reduced oil carryover, and longer ring life. Deep cooling fins maximize surface area for cylinder cooling under high-duty-cycle operation, and deep-bored, threaded holes allow proper head torque for long-term gasket durability.

Heavy-Duty Flywheel and Multi-Belt Drive

The 10 HP pump runs a 20″ cast iron flywheel with two B-style groove belts and nine large cooling fins. The added flywheel mass generates greater kinetic energy, reducing amp draw and energy consumption, while the multi-belt B-width drive provides more grip surface and lower belt tension than the narrow single A-width belts used on lighter machines — less strain on motor and pump bearings, lower noise and vibration, longer belt life.

Continuous Run with Head Unloader

At preset maximum pressure, the pilot valve unloads the compressor and holds the intake valve open, so the piston keeps cycling without compression while cool air circulates through the cylinder to dissipate heat. The motor keeps running instead of cycling on and off — reducing amp draw by up to 60% while unloaded and protecting the motor and magnetic starter from repeated starts under load. For duty cycles over 40%, opening the ball valve connected to the pilot valve allows continuous-run operation.

Dual-Bolt Belt Tensioner

The dual-bolt tensioner makes belt adjustment precise and keeps alignment true while maintaining optimal tension. No pry bars required.

Pump Mounting Riser

The riser raises the pump to allow 360-degree airflow from the flywheel across the pump oil reservoir, with additional airflow under the pump for maximum cooling.

Dual-Timer Automatic Tank Drain

The electric auto drain expels moisture from the air receiver tank on an adjustable cycle — set the interval anywhere from 1 to 45 minutes and set how long the drain stays open. An air muffler is included for quiet water dispensing.

Specifications

Warranty

The compressor carries a 1-year standard warranty against defects in material, workmanship, and parts, including 1 year of warranty labor from an authorized technician. Registering with EMAX and following the extended warranty plan — which includes using EMAX SMART OIL and the published maintenance schedule — extends coverage to a full 5 years. Units ship with break-in oil that must be changed within the first 70 hours, then every 6 months or 1,000 hours, whichever comes first.

The EMAX 5-Year Extended Warranty Kit (kit # EFKIT008AWBS, sold separately) is designed for 5-10 HP Silent Air electric models and includes the components and lubricants required for proper startup and the routine maintenance that supports extended warranty coverage.

The refrigerated air dryer carries its own 1-year standard warranty with 1 year of warranty labor; registering for the extended warranty plan and purchasing one Airbase dryer filter replacement kit per year extends dryer coverage to a full 3 years.

FAQ

What electrical service does it require?

230V single-phase (+/- 10%) with a recommended 60 A breaker. Full load amps are 52.9 A with the 1.15 service factor, and peak starting (locked rotor) draw is 270 A. A magnetic starter is included.

Can it run all day?

The unit is rated for a 60% duty cycle and supports continuous-run operation. For applications over a 40% duty cycle, the ball valve connected to the pilot valve can be opened so the head unloader keeps the motor running unloaded between demand instead of stopping and restarting.

How quiet is it?

EMAX’s patented Silent Air system suppresses intake noise — the loudest source of compressor sound — with baffle plates and high-capacity filter media, achieving up to 50% quieter operation at or below conversational volume. Because it is not an enclosed cabinet, the pump stays fully accessible for service.

What maintenance does it need?

Change the break-in oil within the first 70 hours of operation, then change oil every 6 months or 1,000 hours, whichever occurs first (oil capacity is 2 quarts). The spin-on oil filter and Silent Air filters are serviced with the EFKIT008AWBS kit, and using EMAX-approved oils is required to keep the warranty valid.

Does the dryer remove water from the air?

Yes. The included 58 CFM refrigerated dryer removes moisture from the compressed air, with a built-in 0.001-micron prefilter and 0.005-micron coalescing prefilter. The dual-timer auto drain also expels water that condenses in the tank automatically.
