The EMAX Industrial 13HP Honda GX390 30-Gallon MAXFLO Two-Stage Air Compressor delivers professional-grade compressed air performance in a compact, mobile-ready configuration. Producing an impressive 33 CFM at 100 PSI, this gas-powered compressor combines a proven Honda GX390 engine, EMAX MAXFLO pump technology, and a 30-gallon horizontal ASME-certified air tank for demanding industrial and commercial applications.
Its horizontal tank and compact footprint make this compressor an excellent choice for service trucks, work trailers, mobile repair operations, construction sites, agricultural applications, and remote job sites where dependable compressed air is needed without access to electrical power.
13HP Honda GX390 Gas Engine
Powered by the proven Honda GX390 13HP gas engine, this EMAX compressor is designed to provide dependable power for demanding mobile and field applications. The gas-driven configuration gives technicians and contractors the flexibility to operate pneumatic tools and equipment where electrical service may be unavailable or impractical.
MAXFLO 3-Cylinder Two-Stage Pump ~ More Air from Every Horsepower
At the heart of this compressor is EMAX’s innovative MAXFLO 3-cylinder, two-stage pump. Its unique Y-shaped cylinder configuration is engineered to maximize airflow and operating efficiency while maintaining the rugged durability required for demanding professional use.
MAXFLO technology is designed to deliver up to 30% more air output per horsepower compared with conventional compressor pump designs. The re-engineered pump architecture helps reduce wasted energy while providing easier starting, smoother operation, and dependable compressed air delivery throughout demanding work cycles.
Heavy-Duty Cast-Iron Construction
The MAXFLO pump features rugged solid cast-iron construction engineered for strength, heat management, and long-term reliability. Industrial-grade ceramic disc valves and solid steel connecting rods provide additional durability in demanding operating environments.
Designed for up to 50,000 hours of service life with proper maintenance, the MAXFLO pump provides the durability required by professional users who depend on their compressor day after day.
Splash-Lubricated Compressor Pump ~ Proven Lubrication System
The splash-lubricated compressor pump uses connecting-rod dippers that pass through oil contained in the crankcase during operation. As the pump runs, the dippers distribute lubricant onto the cylinders, pistons, and other internal components to help minimize friction and component wear.
Proper Oil Viscosity & Maintenance
Maintaining the proper compressor oil type, viscosity, and oil level is important for effective splash lubrication. The oil must properly adhere to the internal components and rod dippers so it can be distributed throughout the pump during operation.
Following EMAX’s recommended oil specifications and maintenance intervals helps ensure proper lubrication, reduce premature wear, and maximize compressor pump service life.
Simple, Cost-Effective Maintenance
The EMAX MAXFLO system is designed with straightforward routine maintenance in mind. Unlike more complex compressor systems that may require specialized service procedures, routine MAXFLO maintenance primarily consists of scheduled compressor oil and air filter changes, helping reduce maintenance costs and simplify long-term ownership.
Each compressor is factory-filled with 70-hour break-in oil. Warranty registration is required after purchase to qualify for applicable extended manufacturer warranty coverage.
Belt Drive | Heavy-Duty V-Belt Design ~ Power You Can Rely On
The EMAX heavy-duty V-belt drive system is engineered for efficient power transfer, reduced vibration, and dependable long-term operation. Compared with narrow single A-width belt configurations, EMAX’s wider multi-belt design provides increased belt contact for improved grip and load distribution.
Greater belt surface area provides improved grip and efficient power transfer.
Reduced belt tension helps minimize strain on engine and compressor pump bearings.
Lower noise and vibration promotes smoother compressor operation.
Improved load distribution helps extend belt and drive-system component life.
Heavy-duty construction supports demanding commercial and industrial applications.
The result is a durable, efficient, and low-maintenance belt drive system engineered for thousands of hours of dependable professional service.
Built for Mobile & Industrial Air Demand
With its combination of a 13HP Honda GX390 engine, 33 CFM at 100 PSI, 30-gallon horizontal ASME-certified tank, and MAXFLO 3-cylinder two-stage pump, this EMAX compressor delivers substantial compressed air capability in a configuration designed for mobile professional applications.
Built and performance-tested in Ohio, EMAX air compressors are engineered with reliability, performance, and durability in mind. The EMAX Industrial 13HP Honda GX390 MAXFLO Air Compressor provides a professional-grade compressed air solution for service trucks, mobile technicians, contractors, agricultural operations, and demanding job sites where reliable air power is essential.
