EMAX 5 HP 80-Gallon Two-Stage Air Compressor ESP05V080I3PK-208

The EMAX ESP05V080I3PK-208 is a complete 5 HP shop air system combining an 80-gallon two-stage Silent Air™ piston compressor with a 30 CFM refrigerated air dryer for clean, dry compressed air in demanding work environments. The compressor delivers 19 CFM at 175 PSI maximum pressure and runs on 208–230V three-phase power, making it a strong fit for stationary professional shops. Built around a pressure-lubricated 100% cast-iron pump with an estimated 70,000-hour service life, this system includes a magnetic starter, dual-bolt belt tensioner, pump riser, and automatic tank drain.

The Silent Air™ intake silencer reduces the loudest source of compressor noise by using noise-reducing baffle plates and high-capacity filtration, allowing operation up to 50% quieter while keeping the pump accessible for maintenance. Inside, the two-stage cast-iron pump uses a gear-driven oil system that sends filtered oil directly to critical bearing points through rifle-drilled crankshaft and connecting rod passages. CNC-machined cylinders, disc valves, rebuildable connecting rods, and cast-iron heads are designed to handle continuous-duty operation with reduced wear and easier service over the compressor’s working life.

Designed for automotive repair facilities, fabrication shops, industrial service centers, and professional garages, the ESP05V080I3PK-208 provides reliable airflow for impact tools, sanders, spray equipment, grinders, and other pneumatic applications. The included 30 CFM refrigerated air dryer with built-in prefilters helps remove moisture before air reaches your tools and air lines, while the continuous-run head unloaders, cooling flywheel, belt drive, and automatic drain system support dependable operation during long work sessions.

Features

Pressure-Lubricated Pump
A gear-driven oil pump delivers continuous pressurized lubrication to bearings and high-friction components, improving cooling and extending pump life. Rifle-drilled crankshaft and connecting rods provide direct oil flow, while the spin-on filter, pressure gauge, adjustable regulator, and bleeder valve simplify maintenance and monitoring.

100% Cast Iron Two-Stage Construction
Built with cast iron crankcase, cylinders, cylinder heads, connecting rods, crankshaft, and high-pressure piston for superior durability under high-duty-cycle operation. No aluminum sleeves are used beneath the paint.

Cast Iron Cylinders
CNC-machined and precision-honed cylinders provide accurate tolerances, reduced oil carryover, longer ring life, and improved heat dissipation with deep cooling fins.

Solid Cast Iron Cylinder Heads
Heavy-duty cast iron heads provide strong gasket retention, improved rigidity, and reliable sealing without frequent retorquing. The disc-valve design allows quick inspection and service.

CNC-Machined Disc Valves
Precision-ground concentric disc valves deliver reliable sealing, long service life, and easier maintenance compared with traditional reed-style valves.

Pistons and Rebuildable Connecting Rods
Cast iron high-pressure pistons withstand heavy loads, while CNC-machined connecting rods with replaceable bearing inserts and wrist pins allow full rebuildability. The four-ring piston design improves sealing and reduces oil carryover.

Cast Iron Flywheel
The 16-inch cast iron flywheel stores kinetic energy for smoother operation, reduced amp draw, and improved cooling through integrated airflow fins and dual B-style belts.

Continuous-Run Head Unloaders
The included head unloader system allows the motor to keep running unloaded at preset pressure, reducing repeated starts, lowering wear, and supporting high-duty-cycle applications.

Dual-Bolt Belt Tensioner & Pump Riser
Provides accurate belt alignment and tension without pry bars while the raised pump design improves 360-degree airflow for enhanced cooling.

Dual-Timer Automatic Tank Drain
Automatically removes moisture and condensate with adjustable drain intervals from 1–45 minutes and customizable open duration. Includes an air muffler for quieter operation.

30 CFM Refrigerated Air Dryer
Included dryer removes moisture from compressed air with a built-in 0.001-micron prefilter and 0.005-micron coalescing prefilter to protect equipment and improve air quality.

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. Registration is not required for standard coverage.

Coverage can be extended up to 5 years by registering at emaxwarranty.com, using EMAX SMART Oil, and following the required maintenance schedule. This 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 and maintaining proper oil level.

The included refrigerated air dryer has its own 1-year standard warranty, extendable to 3 years with registration and one annual dryer filter replacement kit. The EFKIT008AWBS extended warranty kit (sold separately) provides the SMART Oil and filters required for 5–10 HP Silent Air electric models.

FAQ

What electrical service does this compressor need?

The compressor requires 208–230V three-phase power with a 14.5A full-load draw (1.15 service factor) and 91A locked-rotor starting current. A 30A breaker is recommended. A magnetic motor starter is included.

Can it run continuously?

Yes. This pressure-lubricated unit is designed for continuous-run operation and includes head unloaders with a 60% duty cycle for sustained shop air demand.

Does it come with an air dryer?

Yes. The package includes a 30 CFM refrigerated air dryer with built-in prefilter and coalescing prefilter to remove moisture from compressed air.

How loud is it?

The patented Silent Air™ silencer reduces intake noise — the main source of compressor sound — providing operation up to 50% quieter and at or below conversational volume while keeping the pump and belts accessible for service.

What maintenance keeps the warranty valid?

For extended compressor coverage, replace the break-in oil within the first 70 hours, then service the oil every 6 months or 1,000 hours using EMAX-approved oil. Maintain proper oil level and complete registration at emaxwarranty.com. Dryer extended coverage requires one annual filter replacement kit.

How does it ship?

The system ships by freight, crated on a pallet. The carrier will contact you to schedule delivery.
