10 HP 38 CFM 460V 3 Phase 120 Gallon Vertical Silent Air Industrial Air Compressor with Auto Drain and Aftercoolers - EMAX ESPR10V120V3-460

The EMAX Silent Air Industrial ESPR10V120V3-460 is a 10HP air compressor that delivers 38 CFM from a 120-gallon vertical tank and runs on 3-phase 460V power. It pairs EMAX's patented Silent Air™ noise suppression with a pressure-lubricated cast iron pump, and it comes equipped with an auto drain and aftercoolers. It suits industrial facilities with 460V three-phase service that need a quieter compressor built for high-stress, continuous-duty environments.

Silent Air™ Noise Suppression

• Up to 50% Quieter: The patented Silent Air™ silencer system achieves up to 50% quieter operation, with noise levels at or below conversational volume. Each 10 dBA drop equals a 50% reduction to the human ear.

• Service-Friendly Design: Enclosed cabinet systems are costly and restrict service access. The Silent Air™ silencer is cost-effective, easy to service and keeps the compressor accessible.

• Intake Noise Reduction: Intake noise is the loudest source of compressor sound. The system targets it with noise-reducing baffle plates and high-capacity filter media.

• Enhanced Air Filtration: The intake system provides up to 1000% more filtration than standard setups.

Pressure Lubrication System

• Gear-Driven Oil Pump: A gear oil pump is mounted to the rear of the crankshaft and generates positive oil pressure. It delivers a continuous flow of oil to each bearing point, which keeps bearings cool and extends pump life.

• Rifle-Drilled Oil Passages: The crankshaft and connecting rods are rifle-drilled for direct oil flow to bearings and other high-friction wear points. Oil travels through the crankshaft into the connecting rod and up to the piston pin and bearing.

• Spin-On Oil Filter: An automotive-style spin-on oil filter keeps the oil clean and simplifies maintenance during oil changes.

• Analog Oil Pressure Gauge: Operators can monitor oil pressure accurately for reliable performance and peace of mind.

• Built for Continuous Duty: Splash-lubricated systems do not deliver oil this precisely. Pressure lubrication puts oil where it's needed, reducing friction, wear and heat in high-stress, continuous-duty environments.

100% Cast Iron Pump Construction

• Cast Iron Major Components: The crankcase, cylinder heads, cylinders, connecting rods, crankshaft and high-pressure piston are all cast iron. Cast iron offers durability and rigidity that aluminum components do not match.

• Cast Iron High-Pressure Pistons: These pistons are designed to withstand heavy loads and help prevent cylinder scoring and pump failure.

• CNC-Machined Connecting Rods: The solid cast iron rods provide maximum rigidity and strength. They keep their strength at the crankshaft end, which is where aluminum rods commonly fail.

• Non-Oil-Absorbent Gaskets: High-quality gaskets minimize oil leakage, provide a more reliable seal and reduce maintenance requirements.

Pistons, Rings & Rebuildability

• Four-Ring Piston Design: Each piston uses four precision overlap rings instead of three. Two oil control rings remove excess oil on the downstroke, and two compression rings seal under compression to prevent blow-by.

• Reduced Oil Carryover: The ring configuration minimizes compression loss, maximizes sealing and extends ring life.

• Fully Rebuildable Connecting Rods: Replaceable bearing inserts and wrist pins allow the connecting rod assembly to be fully rebuilt instead of thrown away, which extends pump life.

• Optional Head Unloaders: Optional head unloaders are ideal for constant-run applications. They relieve the intake valve during operation, which improves pump cooling and reduces wear under heavy workloads.

Heavy-Duty Flywheel & Included Equipment

• 20" Cast Iron Flywheel: The 10HP models use a 20" flywheel with (2) B-style groove belts and 9 large cooling fins. Its added mass generates greater kinetic energy, which reduces amp draw and lowers energy consumption.

• Extended Belt Life & Cooling: The multiple B-groove belts provide a larger contact surface to extend belt life. The optimized cooling fins enhance pump cooling capacity.

• Auto Drain & Aftercoolers: This model comes equipped with an auto drain and aftercoolers.

• 120-Gallon Vertical Tank: The vertical tank configuration provides 120 gallons of air storage.
