The EMAX Silent Air ESPR10V120V3-460 is a 10 HP, 120-gallon two-stage piston air compressor designed for continuous shop and light-industrial applications. Its belt-driven, pressure-lubricated pump delivers 38 CFM at up to 175 PSI, powered by 460V three-phase electricity through a 25-amp circuit. Built for demanding environments, it combines a TEFC motor, Silent Air enclosure, and a pump rated for an estimated 70,000 hours of operation. Requires freight delivery due to its 913 lb uncrated weight.
The two-stage pump uses a spin-on oil filter system to maintain clean lubrication at the bearings, helping extend component life during long operating cycles. A built-in radiator aftercooler cools compressed air before it enters the tank, reducing moisture buildup that can damage air tools and shop piping. The automatic timed tank drain removes collected condensate on a schedule, reducing routine maintenance while helping keep the air system cleaner.
Designed for high-demand automotive and industrial applications, the ESPR10V120V3-460 is a strong fit for professional repair shops, fabrication facilities, paint operations, and businesses running tools that require consistent airflow. The Continuous Run function helps maintain performance during extended jobs like blasting, grinding, and resurfacing by reducing frequent motor starts, while the 120-gallon ETL, ASME, and CRN certified tank provides the capacity needed for sustained shop operation.

Warranty
The ESPR10V120V3-460 includes EMAX’s 1-year standard warranty covering defects in materials, workmanship, and parts from the date of delivery, along with one year of warranty labor from an authorized technician. EMAX also covers ground freight for warranty parts during the first six months.
The warranty can be extended up to 5 years when the unit is registered and maintained according to EMAX’s extended-warranty program using EMAX SMART OIL. Maintenance requires replacing the factory break-in oil within the first 70 hours of operation, then changing the oil every 6 months or 1,000 hours (whichever comes first) while maintaining the proper oil level.
FAQ
What are the electrical requirements?
The compressor requires 460V three-phase power, draws 14.1 full-load amps (1.15 service factor), and requires a dedicated 25-amp circuit. Installation should be completed by a licensed electrician according to NEC and local electrical codes.
Does it include an air dryer?
No. The ESPR10V120V3-460 is a standalone compressor. Its radiator aftercooler removes a significant amount of moisture, but a refrigerated air dryer is recommended for moisture-sensitive applications such as painting or plasma cutting.
How is it installed?
The compressor must be installed on a flat, level concrete surface using rubber anti-vibration pads (maximum 1/4-inch thickness). EMAX recommends 3/8-inch wedge anchors measuring 3.5 inches long, with at least 15 inches of clearance around the unit for proper airflow and service access. The installation area should remain between 35°F and 110°F.
