The EMAX Industrial 7.5HP 80-Gallon 2-Stage Inline Air Compressor is engineered for demanding professional applications that require high airflow, dependable pressure, and exceptional long-term durability. Delivering an impressive 31 CFM at 100 PSI with a maximum pressure of 175 PSI, this single-phase vertical air compressor is an excellent choice for automotive repair shops, fabrication facilities, manufacturing operations, agricultural applications, fleet maintenance facilities, and other high-demand commercial environments.
Designed for up to 60,000 hours of service life with proper maintenance, the compressor combines a rugged all-cast-iron, pressure-lubricated, two-stage reciprocating pump with an industrial-grade electric motor and heavy-duty components. The result is a professional compressed air system engineered to deliver consistent airflow and reliable performance throughout demanding work cycles.
Heavy-Duty Industrial Components
This EMAX 7.5 HP compressor is equipped with an industrial-grade electric motor and magnetic starter for dependable operation and added motor protection. A manual ball-valve tank drain simplifies routine moisture removal, while the durable 80-gallon ASME-certified powder-coated air tank features a 200 PSI tank rating for demanding professional applications.
Silent Air™ Technology
Patented Noise Suppression System
The patented EMAX Silent Air™ System is designed to attack compressor noise at one of its primary sources: the air intake. Incoming air is routed through a series of engineered baffle plates that dissipate intake noise before it reaches the compressor pump, helping provide a significantly quieter working environment.
The low-profile Silent Air™ design can reduce compressor intake noise by more than 35% while maintaining convenient access to critical compressor components. Unlike fully enclosed cabinet systems, the design does not unnecessarily restrict routine inspection, maintenance, or service access.
Advanced Air Filtration
In addition to reducing intake noise, the Silent Air™ system incorporates enhanced filtration to help protect the compressor from airborne contaminants.
Noise-reducing baffle plates help suppress compressor intake noise.
High-capacity filter media helps capture contaminants before they reach the pump.
Four levels of intake air filtration provide enhanced compressor protection.
Provides up to 1000% more filtration compared with standard filtration setups.
Patented Pressure-Lubricated Pump ~ Maximum Protection for Critical Components
The EMAX pressure-lubricated reciprocating pump is engineered to provide continuous lubrication directly to critical internal components. A gear-driven oil pump generates positive oil pressure and delivers a controlled flow of lubricant to bearing and wear points, helping reduce friction, heat, and premature internal wear.
This targeted lubrication system is particularly beneficial in demanding professional environments where compressors experience extended operating cycles and high air demand.
100% Cast-Iron Pump Construction
Major components of the EMAX pump are manufactured from heavy-duty cast iron for superior rigidity, durability, and long-term performance.
Cast-iron crankcase
Cast-iron cylinder heads
Cast-iron cylinders
Cast-iron connecting rods
Cast-iron crankshaft
Cast-iron high-pressure piston
Rifle-Drilled Oil Passages
The crankshaft and connecting rods are rifle-drilled, allowing pressurized oil to flow directly to bearings and other high-friction wear points. This precision lubrication helps maintain a protective oil film throughout the pump and provides additional protection during demanding operating conditions.
Spin-On Oil Filter & Pressure Monitoring
A convenient automotive-style spin-on oil filter helps remove contaminants from the circulating lubricant, providing cleaner oil to critical internal components while simplifying routine filter replacement during scheduled maintenance.
An integrated analog oil pressure gauge allows operators to monitor lubrication system pressure and verify proper operation of the pressure-lubrication system.
Four-Ring Piston Design
The pump utilizes a four-ring piston design with precision-engineered overlap rings to provide effective cylinder sealing. This design helps minimize compression loss, reduce oil carryover, and maintain efficient pump performance during demanding compressor operation.
High-Quality Pump Gaskets
High-quality non-oil-absorbent gaskets provide dependable sealing and help minimize oil leakage. Improved sealing helps reduce maintenance requirements while contributing to the long-term efficiency and durability of the compressor pump.
Optional Head Unloaders
Optional head unloaders are available for demanding constant-run applications. Head unloaders relieve the intake valve during unloaded operation, helping improve pump cooling and reduce unnecessary component wear during extended operating cycles. This makes them especially useful for commercial and industrial environments with sustained compressed air demand.
20" Heavy-Duty Cast-Iron Flywheel
The 7.5 HP compressor pump features a massive 20-inch cast-iron flywheel engineered to improve energy efficiency, operating stability, and pump cooling. The increased flywheel mass generates greater kinetic energy, helping maintain smooth compressor operation while reducing peak motor demand.
The flywheel incorporates nine large cooling fins that move air across the compressor pump during operation. Increased airflow helps dissipate heat and maintain more consistent operating temperatures during demanding duty cycles.
Belt Drive | Heavy-Duty V-Belt Design ~ Power You Can Rely On
The EMAX heavy-duty V-belt drive system is engineered for dependable power transfer, reduced vibration, and long-lasting performance. Unlike compressors that use narrow, single A-width belts, EMAX compressors feature a multi-belt drive system utilizing wider B- and C-width belts to provide greater contact area and improved grip between the motor and compressor pump.
Greater belt surface area provides improved grip and more efficient power transfer.
Reduced belt tension helps minimize unnecessary strain on motor and compressor pump bearings.
Lower noise and vibration promotes smoother, quieter compressor operation.
Improved load distribution helps extend belt life and reduce premature component wear.
Heavy-duty multi-belt construction provides dependable performance in demanding commercial and industrial applications.
The result is a durable, efficient, and low-maintenance air compressor belt drive system designed to deliver thousands of hours of reliable professional performance.
Built for Serious Compressed Air Demand
With 7.5 HP of industrial power, 31 CFM at 100 PSI, 175 PSI maximum operating pressure, an 80-gallon ASME-certified tank, patented pressure-lubricated cast-iron pump, and Silent Air™ Technology, this EMAX compressor provides the airflow and durability required by demanding professional operations.
Built for long-term performance, the EMAX Industrial 7.5HP 80-Gallon 2-Stage Inline Air Compressor delivers a powerful combination of high airflow, advanced lubrication, heavy-duty construction, enhanced filtration, and reduced intake noise for professional shops that depend on reliable compressed air day after day.
