EMAX 7.5 HP 80-Gallon Two-Stage Air Compressor ES07V080V1

The EMAX Silent Air Industrial ES07V080V1 is a 7.5 HP two-stage air compressor with an 80-gallon vertical tank designed for shops that need steady airflow from standard single-phase power. It delivers 31 CFM at 100 PSI and 26 CFM at 175 PSI, providing the output needed for impact tools, grinders, sanders, plasma cutters, and other high-demand applications. The 100% cast-iron pump features pressure lubrication for longer service life, with an estimated 70,000-hour pump life, while the ETL-listed, ASME-certified tank and factory-installed magnetic starter make it ready for professional shop installation.

The patented SilentAir™ noise suppression system reduces intake noise — the loudest source of piston compressor sound — using noise-reducing baffle plates and high-capacity filtration media. It operates at or below conversational volume while keeping the pump accessible for maintenance, unlike fully enclosed cabinet designs. The pressure-lubricated pump uses a gear-driven oil system that continuously feeds filtered oil to bearings and high-friction components through drilled crankshaft and connecting rod passages, helping reduce heat and wear during extended operation.

Built with cast-iron cylinders, rebuildable connecting rods, four-ring pistons, and precision-machined disc valves, this compressor is engineered for demanding daily use rather than occasional air needs. The heavy 20-inch cast-iron flywheel, dual B-belt drive, and vibration isolator pads help improve cooling, reduce vibration, and support reliable operation. It is a strong choice for automotive repair shops, fabrication businesses, professional garages, and serious home workshops that need high airflow with quieter operation.

Features

SilentAir™ Noise Suppression

EMAX’s patented SilentAir™ silencer targets intake noise — the loudest source of sound in a reciprocating compressor — using noise-reducing baffle plates and high-capacity filter media. The result is operation at or below conversational volume without the added cost, heat buildup, and restricted service access of a fully enclosed cabinet. The silencer also functions as a high-capacity intake filter, helping deliver cleaner air to the pump.

Pressure-Lubrication Pump

A gear-driven oil pump mounted to the rear of the crankshaft generates positive oil pressure and continuously supplies lubrication to every bearing point, similar to an automotive engine lubrication system. The crankshaft and connecting rods are gun-drilled to deliver oil directly to piston pins and bearings, while an automotive-style spin-on oil filter keeps the lubricant clean.

A liquid-filled oil pressure gauge provides easy monitoring, a bleeder valve allows quick pump priming, and an adjustable regulator fine-tunes oil pressure across the RPM range. Compared with splash lubrication systems, pressure lubrication provides more consistent cooling and reduced wear during continuous-duty operation.

100% Cast-Iron Construction

All major pump components are constructed from cast iron — including the crankcase, cylinders, cylinder heads, connecting rods, crankshaft, and high-pressure piston. Cast iron is engineered to handle the heat, pressure, and load demands of high-duty-cycle applications better than aluminum designs, with no aluminum sleeves hidden beneath the paint.

The CNC-machined cylinders are precision-honed for accurate concentricity, reducing oil carryover and extending piston-ring life. Deep cooling fins increase surface area for improved heat dissipation during long operating cycles. Solid cast-iron cylinder heads feature deep-bored, threaded bolt holes for reliable torque retention and a disc-valve design that maintains sealing performance without frequent retorquing.

Four-Ring Pistons and Cast-Iron Connecting Rods

The pump uses a four-ring piston design with two oil-control rings that remove excess oil during the downstroke and two compression rings that maintain sealing under pressure. This design improves efficiency, reduces blow-by, and minimizes oil carryover throughout the pump’s service life.

On this two-stage pump, the high-pressure piston is cast iron for maximum durability, while the low-pressure piston uses aluminum construction because it operates under lighter loads of approximately 45 PSI. CNC-machined cast-iron connecting rods feature replaceable bearing inserts and wrist pins, allowing the rod assembly to be rebuilt instead of replaced.

Cast-Iron Flywheel and V-Belt Drive

The heavy cast-iron flywheel stores kinetic energy to smooth operation and reduce amp draw, while integrated cooling fins direct airflow across the pump. The 7.5 HP unit uses a 20-inch flywheel with nine large cooling fins and two B-groove belts.

The multi-belt V-drive provides more contact area than a single narrow belt design, reducing belt tension, minimizing vibration, and lowering strain on motor and pump bearings for improved reliability and longer service life.

CNC-Machined Disc Valves

The compressor uses concentric-ring disc valves that are precision surface-ground for reliable sealing and extended service life. When maintenance is required, the valve can be serviced quickly by removing the retainer, lifting the valve for inspection, and reinstalling it — avoiding the more complex rebuild process associated with feather or reed valve designs.

Specifications

Warranty

Every EMAX compressor includes a 1-year limited warranty covering defects in materials, workmanship, and parts from the date of delivery, including one year of warranty labor through an authorized technician. Coverage extends to 5 years when the compressor is registered and maintained under the EMAX SMART OIL extended-warranty plan. This plan requires the use of the EFKIT008AWBS maintenance kit (sold separately) and compliance with the published oil-change schedule.

Standard technical assistance is available at no charge during and after the warranty period.

FAQ

What electrical service does this compressor need?
