EMAX ESP15V120Y3-208 15 HP Silent Air | 58 CFM | 208/230V 3Ph
15 HP | 58 CFM at 100 PSI | 175 PSI Maximum | 208/230V Three-Phase | 120-Gallon Vertical Receiver
The EMAX ESP15V120Y3-208 E450 Silent Air is an industrial two-stage reciprocating air compressor delivering 58 CFM at 100 PSI. Its cast-iron pressure-lubricated pump, patented Silent Air intake and 120-gallon vertical receiver suit professional shops and industrial facilities with three-phase power.
Before selecting a compressor, compare its rated 58 CFM with all tools and processes that will operate simultaneously. The 120-gallon receiver helps cushion intermittent demand, but does not increase sustained pump capacity.
Key Features and Benefits
- 15 HP, 58 CFM: High airflow for correctly sized shop and production equipment.
- Pressure-lubricated cast-iron pump: Gear-driven oil supply to crankshaft and connecting-rod bearings.
- Silent Air™: Patented intake baffles and filtration reduce intake noise without a full enclosure.
- 120-gallon vertical receiver: Air storage with reduced floor length compared with horizontal tanks.
- Automatic tank drain: Timed discharge of receiver condensate.
- Belt tensioner: Facilitates accurate, repeatable belt adjustment.
- 208/230V three-phase: Designed for facilities with compatible industrial electrical service.
Pressure-Lubricated Pump Construction
EMAX's pressure-lubricated pump family uses a gear oil pump and drilled crankshaft and connecting-rod passages to deliver lubricant to critical bearings. A spin-on oil filter helps remove contaminants and a liquid-filled oil pressure gauge permits operating checks. Cast-iron major pump components, four-ring pistons, concentric disc valves and serviceable bearing assemblies support durability and maintenance access.
Silent Air™, Cooling and Service
Silent Air™ uses noise-reducing baffles and high-capacity intake filter media. EMAX advertises up to 50% quieter operation, depending on the environment and application. The manufacturer's 15 HP pump family uses a heavy-duty cast-iron flywheel and cooling fins; EMAX specifies two drive belts on this particular configuration. Follow the specific model's belt and maintenance instructions.
The adjustable automatic receiver drain helps expel collected moisture. Review the desired operating duty cycle and verify continuous-run/head-unloader equipment with EMAX rather than assuming the unit can operate continuously without limitations.
Technical Specifications
Model-specific manufacturer data: This unit has an APP3Y2062TP pressure-lubricated two-stage pump operating at 815 RPM, with a 1,740 RPM TEFC motor, factory magnetic starter, pump riser and two drive belts. EMAX specifies 41.90 A including the 1.15 service factor, 237 A starting/locked-rotor current, and a 70 A recommended breaker. Have a qualified electrician verify branch circuit and protection requirements.
The pump oil capacity is 3 quarts and the listed service kit is EFKIT009AWB. Equipment weight is 1,138 lb uncrated and 1,287 lb crated. Shipping arrangements should accommodate these weights.

Sizing and Installation Recommendations
Have a qualified electrician confirm the site's three-phase service, motor starting current and branch protection. Maintain clearances around the drive, pump, motor and air intake. Confirm exact dimensions and shipping weight before arranging installation and unloading.
Pair with a suitably sized air dryer and compressed-air filtration where the application requires clean, dry air. See compressor maintenance supplies for periodic service.
Frequently Asked Questions
How much air does this compressor deliver?
EMAX lists 58 CFM at 100 PSI with a maximum working pressure of 175 PSI.
Is this 15 HP compressor single-phase?
No. This ESP15V120Y3-208 is the 208/230V three-phase configuration.
Does the 120-gallon tank provide 58 CFM continuously?
The pump is rated at 58 CFM at 100 PSI. The receiver stores air for intermittent peaks but does not increase the pump's continuous output.
What does the pressure-lubricated pump do differently?
A gear-driven oil pump distributes filtered lubricant through drilled internal passages to critical wear components.
Is the compressor quiet?
Silent Air technology reduces intake sound using patented baffles and high-capacity filtration; EMAX advertises up to 50% quieter operation under applicable conditions.
Does the unit drain condensed water automatically?
Yes, the E450 Silent Air series lists an automatic tank drain, with adjustable discharge timing.
Does it include a refrigerated air dryer?
No. A properly sized dryer and filtration package can be purchased separately for moisture-sensitive applications.
Can I use this compressor for extended high-demand work?
Confirm duty-cycle suitability and the exact continuous-run/head-unloader configuration with EMAX. Do not assume an unrestricted 100% duty rating.
What electrical breaker is required?
The exact current and protection requirements should be confirmed from this model's data sheet and by a qualified electrician before installation.
