EMAX ESP10V120V3-460 10 HP Silent Air | 38 CFM | 460V 3Ph

10 HP | 38 CFM at 100 PSI | 175 PSI Maximum | 460V Three-Phase | 120-Gallon Vertical Receiver

The EMAX ESP10V120V3-460 E450 Silent Air is an industrial two-stage reciprocating air compressor with a pressure-lubricated pump, patented intake-noise suppression, and a large vertical air receiver. Designed for facilities with 460V three-phase service, it delivers 38 CFM at 100 PSI for demanding commercial shop and industrial pneumatic applications.

The 120-gallon tank increases stored-air capacity for intermittent peaks, but it does not increase continuous compressor output. Match the combined CFM requirements of tools and processes to the compressor's actual rating.

Features and Benefits

• Pressure-lubricated two-stage pump: Dedicated filtered oil delivery to internal bearings and connecting-rod components.
• Cast-iron construction: Heavy-duty crankcase, cylinders, heads, crankshaft and high-pressure piston in the EMAX pressure-lubricated pump family.
• Silent Air™: Patented intake sound-reduction baffles and high-capacity filtration.
• 120-gallon vertical receiver: Additional stored air for intermittent surges without the length of a horizontal receiver.
• Automatic condensate drain: Helps remove water accumulating in the receiver.
• Belt tensioner: Simplifies periodic belt adjustment.
• 460V three-phase power: Appropriate for industrial electrical installations equipped for this voltage.

Pressure-Lubricated Pump Technology

The EMAX pressure-lubricated pump family uses a gear-driven oil pump, rifle-drilled crankshaft and connecting-rod passages, and a replaceable spin-on oil filter. A liquid-filled pressure gauge assists oil-pressure monitoring. Four-ring piston construction, replaceable bearing inserts and wrist pins, and serviceable concentric disc valves are designed to support maintenance and long equipment life.

The major pump components are cast iron, while the low-pressure piston in two-stage models uses aluminum to reduce reciprocating mass. Perform oil, filter and belt service according to EMAX's maintenance instructions.

Silent Air™ and Cooling

EMAX's Silent Air intake uses noise-reducing baffle plates with high-capacity filter media. The manufacturer advertises up to a 50% noise reduction for its Silent Air technology, depending on the operating environment. Unlike a full acoustic enclosure, the system retains access to the pump, motor and drive components.

EMAX specifies a 20-inch cast-iron flywheel with two B-section grooves and nine cooling fins for its 7.5 and 10 HP pressure-lubricated pump family. Proper belt tension, air circulation and periodic intake-filter maintenance remain important.

80-Gallon vs. 120-Gallon and E350 vs. E450

The comparable 80-gallon and 120-gallon 10 HP Silent Air configurations are rated at 38 CFM at 100 PSI. The 120-gallon receiver has greater storage capacity, not greater compressor displacement. Compared with the more basic E350 range, the E450 adds maintenance-oriented features such as an automatic tank drain and belt tensioner. Select based on operating requirements and desired service features.

Technical Specifications

Applications and Installation Guidance

• Automotive repair, fabrication and general maintenance shops with adequate three-phase electrical service.
• Industrial air-tool applications requiring up to 38 CFM at the published 100 PSI rating.
• Install with suitable ventilation, equipment clearance and appropriately engineered electrical protection.
• Confirm model-specific amperage, shipping weight and unloading equipment before ordering.

For air quality and moisture control, pair the compressor with a suitably sized air dryer, compressed-air filtration, and maintenance supplies.

Frequently Asked Questions

How much air does this compressor deliver?

The EMAX ESP10V120V3-460 delivers 38 CFM at 100 PSI and has a maximum pressure of 175 PSI.

Is this model single-phase?

No. The ESP10V120V3-460 is configured for 460V three-phase power.

Does a 120-gallon receiver increase the compressor's CFM?

No. The larger receiver stores additional compressed air to help handle intermittent demand, but it does not increase the pump's continuous rated output.

How does the pressure-lubricated pump work?

A gear-driven oil pump supplies filtered lubricant to critical internal wear surfaces through drilled oil passages, unlike a pump relying only on splash lubrication.

Does Silent Air make the compressor completely silent?

No. The patented intake baffle and filtration design reduces intake noise. EMAX advertises up to 50% quieter operation under suitable conditions.

Does the E450 include automatic drainage?

Yes. The manufacturer lists an automatic receiver drain on this E450 configuration to discharge accumulated moisture.

Does this compressor include an air dryer?

No. An appropriately sized refrigerated or other air dryer is selected separately based on the air-quality requirements of the application.

Is a head unloader included?

Head-unloader configurations should be confirmed for the exact unit and intended duty cycle. A continuous-run feature does not automatically establish a 100% duty-cycle rating.

What electrical protection does the unit need?

Have the installation evaluated for 460V three-phase supply. Confirm breaker sizing, full-load amperage and starting current from the manufacturer data sheet and local electrical requirements.
