EMAX ESP15V120Y3-460 15 HP Silent Air | 58 CFM | 460V 3Ph

15 HP | 58 CFM per Model Specification | 175 PSI Maximum | 460V Three-Phase | 120-Gallon Vertical Receiver

The EMAX ESP15V120Y3-460 E450 Silent Air is a heavy-duty, two-stage reciprocating compressor for manufacturing, automotive service and industrial shops with 460V three-phase service. It combines a cast-iron pressure-lubricated pump with patented Silent Air™ intake noise suppression, an automatic tank drain, and a vertical 120-gallon air receiver.

For equipment sizing, compare the required tool and process CFM at operating pressure against the published rating. EMAX's current model sheet states 58 CFM, while its September 2026 pricing file states 57 CFM. The difference is being verified before publication.

Key Features and Benefits

• 15 HP two-stage industrial piston compressor: High-capacity shop air for correctly sized pneumatic systems.
• Pressure-lubricated APP3Y2062TP pump: Gear-driven oil pump and filtered lubrication to critical components.
• Silent Air™ intake: Patented sound-suppression baffles and high-capacity filtration media.
• 120-gallon vertical receiver: Air storage to buffer intermittent demand without increasing pump output.
• TEFC three-phase motor: 1,740 RPM industrial motor designed for 460V service.
• Automatic timed drain: Helps expel condensed water from the receiver.
• Magnetic starter, pump riser and belt tensioner: Manufacturer-confirmed equipment for starting control, cooling airflow and drive service.

Pressure-Lubricated Cast-Iron Pump

A gear-driven oil pump sends lubricant through rifle-drilled crankshaft and connecting-rod passages to internal bearing surfaces. EMAX's pump family incorporates an automotive-style spin-on filter and an oil pressure gauge for service monitoring. Cast-iron crankcase, cylinders, heads, crankshaft, rods and high-pressure pistons are designed for demanding operation; the low-pressure two-stage piston is aluminum to limit reciprocating mass.

Four-ring pistons help control blow-by and oil carryover. Replaceable bearing components and serviceable concentric disc valves support long-term maintenance. The APP3Y2062TP pump runs at 815 RPM and requires 3 quarts of oil.

Silent Air™, Cooling and Drive Design

The patented Silent Air intake uses acoustic baffles and high-capacity filtration to reduce intake sound, with EMAX advertising up to 50% quieter operation under qualifying conditions. The factory pump riser improves cooling airflow beneath the pump crankcase. The model-specific sheet confirms two drive belts and a belt tensioner for easier adjustment.

Installation and Electrical Considerations

This model is supplied for 460V three-phase power. EMAX lists 20.90A full-load current including the 1.15 service factor, 118A peak starting/locked-rotor current, and a 35A recommended breaker. A qualified electrician must verify conductor sizing, protection and local code requirements. The unit weighs 1,131 lb uncrated and 1,280 lb crated; plan unloading and placement accordingly.

Technical Specifications

Choose the Right System

A 120-gallon receiver increases stored air for short peaks but does not increase sustained CFM. For moisture-sensitive equipment, pair the compressor with a properly sized air dryer and compressed-air filtration. Find maintenance supplies for scheduled service.

Frequently Asked Questions

How much air does this compressor supply?

The current EMAX model sheet lists 58 CFM; the September 2026 pricing file lists 57 CFM. Both sources list the model as a 15 HP unit. Verify the final published airflow rating with EMAX before release.

Does this model operate on 230V?

No. ESP15V120Y3-460 is the 460V three-phase configuration. A separate 208/230V model is available.

What pump and motor does it use?

EMAX specifies the APP3Y2062TP pressure-lubricated two-stage pump at 815 RPM, paired with a 1,740 RPM TEFC motor.

What circuit protection is recommended?

The manufacturer lists a 35A recommended breaker, 20.90A full-load current with service factor, and 118A starting/locked-rotor current. A qualified electrician should validate the installation.

Does it include a magnetic starter?

Yes. EMAX identifies a magnetic starter on this model.

What are the benefits of pressure lubrication?

A gear-driven oil pump circulates filtered oil to crankshaft and connecting-rod wear points through drilled passages, rather than depending solely on splash lubrication.

Is the tank drain automatic?

Yes. An adjustable timed condensate drain is fitted to the air receiver.

Can it run continuously?

Verify the exact head-unloader arrangement and acceptable duty cycle for continuous-run applications. Do not infer a 100% duty-cycle rating from the listed features.

Which service kit and oil quantity apply?

The listed service kit is EFKIT009AWB and the pump holds 3 quarts of oil. Follow the official EMAX maintenance schedule.
