The EMAX Silent Air™ 7.5HP 80-Gallon Industrial Air Compressor is engineered for serious compressed air demand, combining industrial-grade durability, high-volume airflow, and advanced noise reduction in one professional system. Delivering an impressive 26 CFM at 100 PSI, this two-stage air compressor is an excellent choice for automotive repair shops, manufacturing facilities, agricultural operations, fabrication shops, and demanding commercial applications.
Designed for up to 50,000 hours of service life with proper maintenance, the compressor features a rugged all-cast-iron, 3-cylinder, two-stage, splash-lubricated pump. The two-stage design provides dependable compressed air performance for applications requiring consistent airflow and pressure throughout demanding work cycles.
Heavy-Duty 1740 RPM Industrial Motor
A powerful 7.5 HP, 1740 RPM industrial-duty motor provides dependable performance while operating at a lower speed than many high-RPM compressor motors. This helps reduce heat, operating noise, and component wear, contributing to longer motor life, reduced maintenance requirements, and improved overall compressor reliability.
Industrial Magnetic Starter
An integrated industrial magnetic starter provides additional motor protection for demanding commercial environments. The system offers overload protection and low-voltage restart protection, helping improve operating safety while protecting the motor and supporting dependable long-term compressor performance.
80-Gallon ASME-Certified Ring Base Tank
The heavy-duty 80-gallon ASME-certified ring base air tank provides substantial compressed air storage for high-demand applications. Increased storage capacity helps reduce compressor cycling, maintain more consistent air delivery, and improve overall system efficiency. The ring base provides a stable foundation, while the durable powder-coated finish helps protect the tank against corrosion and demanding shop conditions.
Additional industrial components include a pressure switch factory set to 145 PSI, manual tank drain with ball valve, 18-gauge steel belt guard, isolator pads, and a large 3/4-inch air outlet designed to provide unrestricted airflow to compatible pneumatic tools and shop equipment.
Silent Air™
Patented Noise Suppression System – Up to 50% Quieter
EMAX Silent Air™ Technology is engineered to dramatically reduce compressor intake noise, one of the loudest sources of sound produced by a reciprocating air compressor. The patented noise suppression system routes incoming air through specially engineered baffle chambers to provide significantly quieter operation while maintaining the airflow required for demanding professional applications.
The Silent Air™ system can provide up to 50% quieter perceived operation while avoiding the accessibility limitations associated with fully enclosed compressor cabinets. This allows critical compressor components to remain readily accessible for inspection, maintenance, and service.
Advanced Air Filtration
Silent Air™ combines noise suppression with enhanced intake filtration to help protect the compressor and promote dependable long-term performance.
Noise-reducing baffle plates help suppress compressor intake noise.
High-capacity filter media helps capture airborne contaminants before they enter the pump.
Provides up to 1000% more filtration compared with standard filtration setups.
Four stages of intake air filtration help protect internal compressor components.
The result is a quieter, cleaner-running industrial air compressor designed to provide the performance professional shops need without unnecessary workplace noise.
3-Cylinder Two-Stage Splash-Lubricated Pump
Heavy-Duty Cast-Iron Construction
At the heart of this EMAX compressor is a rugged 3-cylinder, two-stage, all-cast-iron pump engineered for demanding commercial and industrial service. The two-stage configuration compresses air progressively, providing the consistent pressure and airflow required for professional pneumatic equipment and high-demand shop applications.
Proven Splash Lubrication
The splash-lubricated compressor pump uses connecting-rod dippers that pass through oil in the crankcase as the compressor operates. This movement distributes lubricant onto the cylinders, pistons, and other critical internal components, helping minimize friction and wear.
Using the correct compressor oil, viscosity, and oil level is important for proper splash lubrication. Following EMAX’s recommended oil specifications and maintenance intervals helps maintain effective lubrication, reduce premature wear, and maximize pump service life.
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 performance. Unlike systems that rely on narrow, single A-width belts, EMAX compressors utilize a multi-belt drive system with wider B- and C-width belts to provide increased contact area and improved grip.
Greater belt surface area provides improved grip and efficient power transfer.
Reduced belt tension helps minimize strain on motor and compressor pump bearings.
Lower operating noise and vibration promotes smoother compressor performance.
Improved load distribution helps extend belt and drive-system component life.
Heavy-duty multi-belt construction is designed for demanding commercial and industrial applications.
The result is a durable, efficient, and low-maintenance belt drive system engineered to provide thousands of hours of dependable professional service.
Built for Professional Air Demand
With 7.5 HP of industrial power, 26 CFM at 100 PSI, an 80-gallon ASME-certified tank, a 3-cylinder two-stage cast-iron pump, and patented Silent Air™ Technology, this EMAX compressor provides the performance required for demanding professional environments. It is ideally suited for automotive service equipment, pneumatic tools, fabrication equipment, maintenance operations, manufacturing applications, and other high-demand compressed air systems.
Built and performance-tested in Ohio, EMAX compressors are engineered around long-term reliability, durability, and professional performance. Backed by a strong manufacturer warranty, the EMAX Silent Air™ 7.5HP 80-Gallon Industrial Air Compressor is built to keep demanding shops and commercial operations supplied with dependable compressed air day after day.
