EMAX 5 HP 80-Gallon Two-Stage Air Compressor ESP05V080I3PK-460

The EMAX Silent Air Industrial Plus ESP05V080I3PK-460 is a 5 HP, 80-gallon two-stage air compressor package designed for shops that need dependable compressed air throughout the workday. Running on 460V three-phase power, it delivers 19 CFM at 100 PSI and includes a matched 30 CFM refrigerated air dryer to remove moisture before it reaches your tools and air lines. What separates it from standard shop compressors is the patented Silent Air™ intake silencer, which reduces operating noise by up to 50% while keeping the pump accessible for routine service. The unit includes a magnetic starter, electric auto drain, and pump riser for easier installation and maintenance.

The compressor uses a pressure-lubricated, 100% cast-iron pump engineered for continuous-duty operation. A gear-driven oil pump sends filtered oil directly to critical bearing points, while rifle-drilled crankshafts and connecting rods provide consistent lubrication where wear occurs. The cast-iron construction helps the pump handle heat and heavy workloads, and the estimated 70,000-hour pump life makes it suited for shops that depend on reliable air production. The included refrigerated dryer adds moisture control with built-in 0.001-micron and 0.005-micron prefilters, helping protect equipment, finishes, and air-powered tools.

A strong fit for professional repair shops, fabrication facilities, body shops, and industrial garages that require clean, consistent compressed air for impact tools, sanders, spray equipment, and other high-demand applications. The 80-gallon vertical tank design saves floor space while providing stored air capacity for demanding shop environments.

Features

Silent Air™ Patented Silencer
Reduces intake noise — the loudest source of compressor sound — with noise-reducing baffle plates and high-capacity filtration media. Delivers quieter operation at or below conversational volume while keeping the pump accessible for service.

Pressure-Lubricated Pump
A rear-mounted gear oil pump provides continuous positive oil pressure to bearings and high-friction components. Features rifle-drilled crankshaft and connecting rods, spin-on oil filter, liquid-filled pressure gauge, and adjustable regulator for reliable lubrication and monitoring.

100% Cast-Iron Pump Construction
Built with CNC-machined cast-iron crankcase, cylinders, and cylinder heads for durability under high-duty-cycle operation. Precision-honed cylinders with deep cooling fins improve heat dissipation, reduce oil carryover, and extend component life.

Cast-Iron Cylinder Heads & Disc Valves
Solid cast-iron heads provide strong gasket retention and long-term rigidity. CNC-machined disc valves deliver reliable sealing, extended service life, and quick inspection compared with traditional reed-style valves.

Cast-Iron Pistons & Rebuildable Connecting Rods
High-pressure cast-iron pistons resist wear under heavy loads, while solid cast-iron connecting rods with replaceable bearing inserts and wrist pins allow complete rebuildability. Four-ring piston design reduces blow-by and oil carryover.

Heavy Cast-Iron Flywheel & Multi-Belt Drive
The 16-inch cast-iron flywheel stores kinetic energy to reduce amp draw and improve efficiency. Dual B-style belts, cooling fins, and multi-belt drive design reduce vibration, lower belt tension, and extend system life.

Continuous-Run Head Unloaders
Supports automatic head-unloader operation for high-duty-cycle applications. The system allows the motor to continue running unloaded, reducing wear from repeated starts and improving cooling during operation.

Electric Auto Drain & Pump Riser
Dual-timer automatic drain removes tank moisture with adjustable 1–45 minute cycles, while the pump riser improves airflow around the oil reservoir and pump for enhanced cooling.

30 CFM Refrigerated Air Dryer
Includes a matched refrigerated dryer that removes moisture from compressed air with a built-in 0.001-micron prefilter and 0.005-micron coalescing prefilter for cleaner, drier air.

Specifications

Warranty

The compressor includes a 1-year standard warranty covering defects in materials, workmanship, and parts from the date of delivery, including 1 year of warranty labor from an authorized technician. Compressor coverage can be extended up to 5 years by registering for the EMAX extended warranty plan, using EMAX-approved oil, and following the required maintenance schedule.

The included refrigerated air dryer has its own 1-year standard warranty, extendable up to 3 years by registering for the extended plan and replacing the dryer filter kit annually. The EMAX 5-Year Extended Warranty Kit (EFKIT008AWBS, sold separately) supports 5–10 HP Silent Air electric models.

Required maintenance includes replacing the factory break-in oil within the first 70 hours of operation, then changing oil every 6 months or 1,000 hours, whichever comes first, using EMAX-approved oil.

FAQ

What electrical service does it need?

The compressor requires 460V three-phase power with a 7.3A full-load current (1.15 service factor), 45.4A locked-rotor starting current, and a recommended 15A breaker. A magnetic starter is included.

Can it run continuously?

Yes. The pump is rated for a 60% duty cycle and supports continuous-run operation through its head-unloader system, which is recommended for applications above 40% duty cycle.

Is the air dryer included?

Yes. The package includes a 30 CFM refrigerated air dryer with built-in 0.001-micron and 0.005-micron prefilters for moisture removal and cleaner compressed air.

What oil and maintenance does it require?

Replace the factory break-in oil within the first 70 hours, then change oil every 6 months or 1,000 hours using EMAX-approved oil. Maintaining this schedule and registering the extended warranty plan are required for extended coverage.

How does it ship?

The system ships by freight, crated at 49 × 46 × 87 inches.
