EMAX ESPR15V120Y3-460 Silent Air Industrial 15HP Air Compressor – 38 CFM, 3-Phase 460V, 120-Gal Vertical, Pressure Lube Pump, Auto Drain & Aftercoolers

The EMAX Silent Air Industrial ESPR15V120Y3-460 is a 15 HP air compressor that delivers 38 CFM from a 120-gallon vertical tank and runs on 3-phase 460V power. It pairs a pressure-lubricated, all-cast-iron pump with EMAX's patented Silent Air™ noise suppression system and includes an auto drain and aftercoolers. It suits industrial shops and facilities that need dependable compressed air in high-stress, continuous-duty environments without the noise of a conventional compressor.

Silent Air™ Noise Suppression

• Up to 50% Quieter: The patented 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: Unlike enclosed cabinet systems, which are costly and restrict service access, the Silent Air™ silencer is cost-effective, easy to service and keeps the compressor accessible.

• Intake Noise Control: The system targets intake noise, the loudest source of compressor sound. It uses 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-driven oil pump mounted to the rear of the crankshaft generates positive oil pressure. It delivers a continuous flow of oil to each bearing point, keeping bearings cool and extending pump life.

• Rifle-Drilled Crankshaft & Rods: The crankshaft and connecting rods are rifle-drilled, sending oil directly to bearings and other high-friction wear points.

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

• Oil Pressure Gauge: An analog pressure gauge lets operators monitor oil pressure accurately.

• Built for Continuous Duty: Unlike splash-lubricated systems, pressure lubrication delivers oil precisely where it's needed. This reduces 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. This gives the pump durability and rigidity that aluminum components do not offer.

• Cast Iron High-Pressure Pistons: The high-pressure pistons are designed to withstand heavy loads, which helps prevent cylinder scoring and pump failure.

• CNC-Machined Connecting Rods: The solid cast iron connecting rods provide maximum rigidity and strength. They also stay strong at the crankshaft end, where aluminum rods commonly fail.

• Fully Rebuildable: Replaceable bearing inserts and wrist pins make the connecting rod assembly fully rebuildable rather than throw-away, which extends pump life.

Sealing & Wear Protection

• Four-Ring Piston Design: The pistons use precision-engineered overlapping rings. Two oil control rings remove excess oil on the downstroke, and two compression rings seal under compression to prevent blow-by. This minimizes compression loss, reduces oil carryover and extends ring life.

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

• 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 Features

• 24" Cast Iron Flywheel: The 15 HP pump uses a 24" heavy-duty cast iron flywheel. Its added mass generates greater kinetic energy, reducing amp draw and lowering overall energy consumption.

• Triple B-Groove Belts: Three B-style groove belts provide a larger contact surface area, which extends belt life.

• Cooling Fins: Six large cooling fins on the flywheel boost the pump's cooling capacity.

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