The EMAX EP10DW120V3-208 is a NEMA4 compliant, weather-resistant duplex air compressor rated at 10 HP and 76 CFM, mounted on a 120-gallon horizontal tank with an alternating switch. It is configured for 208V 3-phase power. Its pressure-lubricated, cast iron pump design suits shops and facilities that need dependable air in continuous-duty, high-stress environments.
System Configuration
Duplex Design with Alternating Switch: The duplex configuration includes an alternating switch and is built for demanding compressed-air applications.
NEMA4 Compliant, Weather-Resistant: Built to NEMA4 compliant, weather-resistant standards.
120-Gallon Horizontal Tank: A large horizontal receiver tank supports the system's 76 CFM output.
208V 3-Phase Power: This unit is configured for 208V 3-phase electrical service.
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, keeping bearings cool and extending pump life.
Rifle-Drilled Crankshaft and Connecting Rods: Oil flows through the crankshaft to the rifle-drilled passage in each connecting rod and up to the piston pin and bearing. This lubricates key high-friction wear points.
Spin-On Oil Filter: An automotive-style spin-on filter keeps oil clean and simplifies maintenance during oil changes.
Analog Oil Pressure Gauge: Lets operators monitor oil pressure accurately.
Better Than Splash Lubrication: Pressure lubrication delivers oil precisely where it is needed. Compared with splash-lubricated systems, it reduces friction, wear, and heat in 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 greater durability and rigidity than aluminum.
Cast Iron High-Pressure Pistons: Designed to withstand heavy loads and to prevent cylinder scoring and pump failure.
CNC-Machined Solid Cast Iron Connecting Rods: The rods provide maximum rigidity and keep their strength at the base and at the crankshaft end, which is where aluminum rods commonly fail.
Fully Rebuildable Rod Assembly: Replaceable bearing inserts and wrist pins allow the connecting rods to be rebuilt instead of thrown away.
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. The result is less compression loss, less oil carryover, and longer ring life.
CNC-Machined Disc Valves: These concentric ring valves are precision surface-ground for superior sealing and long service life. They are 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.
Non-Oil-Absorbent Gaskets: High-quality gaskets minimize oil leakage and reduce maintenance requirements.
Flywheel and Cooling
Heavy-Duty Cast Iron Flywheel: The 10 HP pump uses a 20" flywheel. Its added mass generates greater kinetic energy, which reduces amp draw and lowers overall energy consumption.
B-Style Groove Belts: Two B-style groove belts provide a larger contact surface area to extend belt life.
Optimized Cooling Fins: Nine large cooling fins enhance the pump's cooling capacity.
Head Unloader Ready: All valves are engineered to support an automatic head unloader system. Head unloaders relieve the intake valve during operation, which improves pump cooling and reduces wear in constant-run applications.
