EMAX EP07DW120V3-208 NEMA4 Compliant Weather-Resistant Duplex 15HP Air Compressor, 62 CFM, 208V 3-Phase, 120-Gal Horizontal Tank with Alternating Switch

The EMAX EP07DW120V3-208 is a NEMA4 compliant, weather-resistant duplex air compressor rated at 15 HP and 62 CFM. It runs on 208V 3-phase power and is built on a 120-gallon horizontal tank with an alternating switch. Its pressure-lubricated, cast iron pump design suits shops and facilities that need dependable air in high-stress, continuous-duty environments.

Duplex, Weather-Resistant Package

• NEMA4 Compliant: The weather-resistant design is NEMA4 compliant.

• Duplex Configuration: The duplex setup includes an alternating switch.

• Power and Output: The 15 HP unit delivers 62 CFM on 208V 3-phase electrical service.

• Tank: The 120-gallon horizontal tank provides air storage.

Pressure Lubrication System

• Gear-Driven Oil Pump: An oil pump mounted to the rear of the crankshaft generates positive oil pressure. It delivers a continuous flow of oil to each bearing point, which reduces friction and internal wear and keeps bearings cool.

• Rifle-Drilled Crankshaft and Connecting Rods: Oil flows directly to key wear points, including bearings and the piston pin, for continuous lubrication.

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

• Analog Oil Pressure Gauge: Operators can monitor oil pressure accurately.

• Critical Components Coverage: Unlike splash-lubricated systems, pressure lubrication delivers oil precisely where it's needed. This reduces friction, wear, and heat under demanding conditions.

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 greater durability and rigidity than aluminum.

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

• CNC-Machined Solid Cast Iron Connecting Rods: The rods provide maximum rigidity and strength, including at the crankshaft end where aluminum rods commonly fail.

• Fully Rebuildable Rods: Replaceable bearing inserts and wrist pins allow the connecting rod assembly to be rebuilt rather than thrown away, extending pump life.

Sealing and Valve Design

• Four-Ring Piston Design: Two oil control rings remove excess oil on the downstroke, and two overlapping compression rings seal under compression to prevent blow-by. Together they minimize compression loss, reduce oil carryover, and extend ring life.

• CNC-Machined Disc Valves: These concentric ring valves are precision surface-ground for superior sealing and extended service life. They are significantly more reliable than feather or fixed reed valves.

• Quick Valve Service: To service a valve, remove the retainer, lift out the valve for inspection, and reinstall it within minutes.

• Head Unloader Ready: All valves are engineered to support an automatic head unloader system. Head unloaders relieve the intake valve during constant-run operation, which improves pump cooling and reduces wear.

• Non-Oil-Absorbent Gaskets: High-quality gaskets minimize oil leakage and reduce maintenance requirements.

Heavy-Duty Flywheel

• Cast Iron Mass: The heavy-duty cast iron flywheel generates greater kinetic energy. This reduces amp draw and lowers overall energy consumption.

• Multiple B-Groove Belts: The larger belt contact surface area helps extend compressor belt life.

• Optimized Cooling Fins: The fins are engineered to enhance pump cooling capacity.
