EMAX ESP10V080V3-460 10 HP Silent Air | 38 CFM | 460V 3Ph

10 HP | 38 CFM at 100 PSI | 175 PSI Maximum | 460V Three-Phase | 80-Gallon Vertical Tank

The EMAX ESP10V080V3-460 E450 Silent Air is a pressure-lubricated two-stage industrial piston compressor for 460V three-phase shops requiring meaningful airflow with straightforward service access. The 80-gallon vertical receiver, patented Silent Air™ intake, timed automatic tank drain, pump riser and belt tensioner make this a carefully equipped compressed-air platform for repair, fabrication and manufacturing operations.

Its rated 38 CFM at 100 PSI should be compared with the actual combined demand of connected tools and equipment. For sustained production usage, evaluate required running hours and the application duty cycle as well as CFM.

Key Features and Benefits

• 10 HP, 38 CFM at 100 PSI: High-volume two-stage piston compression.
• 460V three-phase TEFC motor: Industrial power configuration with enclosed, fan-cooled motor construction.
• 175 PSI maximum working pressure: Supports appropriately regulated shop applications.
• Pressure-lubricated cast-iron pump: Filtered oil is directed to critical bearing and connecting-rod surfaces.
• Patented Silent Air™ intake: Noise-reducing baffles and high-capacity filtration media.
• 80-gallon vertical tank: Receiver storage in a space-conscious footprint.
• Automatic dual-timer tank drain: Condensate removal with adjustable intervals.
• Dual-bolt belt tensioner: Accurate, service-friendly tension and alignment adjustment.
• Pump riser and magnetic starter: Factory-listed cooling and electrical equipment.

Pressure-Lubricated Pump: Why It Matters

The APP4V1043TP pump uses a gear-driven oil pump to provide continuous lubrication to crankshaft and connecting-rod wear points. Rifle-drilled passages distribute oil internally, while an automotive-style spin-on filter removes contaminants. A liquid-filled oil pressure gauge helps monitor operating pressure. Regular oil and filter changes remain important.

Built for Maintenance and Long-Term Service

EMAX describes cast-iron crankcases, cylinder heads, cylinders, connecting rods, crankshafts and high-pressure pistons for its pressure-lubricated pump family. The two-stage low-pressure piston uses aluminum for reduced reciprocating mass. Four-ring piston construction, replaceable bearing inserts and wrist pins, and removable concentric disc valves help maintain sealing and provide service access.

The 10 HP pump family uses a 20-inch cast-iron flywheel with nine cooling fins and two B-style belt grooves. The broader drive-belt contact area helps transmit power reliably while distributing belt load. This model's pump riser also improves airflow beneath the crankcase.

Silent Air™ Intake Noise Reduction

The patented Silent Air™ intake system channels incoming air past sound-reducing baffles and high-capacity filter media. EMAX advertises up to 50% noise reduction for the technology, depending on application conditions. The compressor remains accessible without an enclosing sound cabinet.

Automatic Drain and Belt Tensioner

EMAX's dual-timer drain design allows interval adjustment from 1 to 45 minutes and adjustable valve-open time to release accumulated receiver condensate. Its dual-bolt belt tensioner allows adjustment without levering against the motor. These upgrades reduce routine service friction compared with simpler piston configurations.

E350 vs. E450: Choosing the Correct 10 HP Model

The comparable E350 and E450 10 HP configurations share a published 38 CFM at 100 PSI rating. The E450 adds a timed automatic drain, belt tensioner and pump riser. These features improve equipment servicing and cooling rather than increasing the rated airflow. For facilities with 208/230V instead of 460V three-phase, select the appropriate separate electrical configuration.

Technical Specifications

Sizing and Installation Considerations

• Have a qualified electrician confirm 460V three-phase supply, starting loads, conductor sizing and circuit protection.
• Review combined CFM demands of all tools expected to operate at the same time.
• Allow service access and ventilation for the motor, intake, belts and pump.
• Evaluate compressor duty cycle when demand is sustained rather than intermittent.

Moisture-sensitive work may require a correctly sized air dryer and compressed-air filtration. Find maintenance supplies for proper service.

Frequently Asked Questions

What airflow does the ESP10V080V3-460 supply?

It delivers 38 CFM at 100 PSI with a maximum pressure of 175 PSI.

Will this compressor work on 230V three-phase power?

No. This model is specified for 460V three-phase service. Choose a correctly configured 208/230V variant if needed.

What is the pump lubrication system?

A gear-driven pressure-lubrication system supplies filtered oil through drilled passages to critical bearings. Follow EMAX oil and filter service intervals.

Does the unit have a magnetic starter?

Yes. EMAX lists a magnetic starter as standard on this configuration.

What are the electrical requirements?

EMAX lists 14.10 amps including the 1.15 service factor, 85.4 starting/locked-rotor amps, and a 25A recommended breaker. Have an electrician verify the installation.

Does it automatically remove tank water?

Yes. The automatic drain uses adjustable timing to discharge condensed moisture from the receiver.

What is different about E450 compared with E350?

The E450 adds convenience features such as an automatic tank drain, belt tensioner and pump riser while sharing the published 38 CFM output of corresponding E350 models.

Can it run continuously?

Head-unloader and continuous-run configurations need to be assessed for the application. Do not treat this piston unit as 100% duty cycle without explicit confirmation.

What service kit is specified?

EMAX lists EFKIT008AWBS. Extended warranty eligibility depends on registration and scheduled maintenance.
