The EMAX 7.5 HP three-phase rotary screw air compressor combines continuous-duty compressed air production with integrated moisture control in a complete package built around a 120-gallon horizontal receiver tank. Its oil-injected rotary screw air end is engineered for up to 100% duty cycle operation, delivering a steady 24 CFM at up to 145 PSI for shops and light-industrial applications that need consistent airflow throughout the workday. The built-in 30 CFM refrigerated air dryer removes moisture before it reaches air lines and equipment, while the system’s three-phase TEFC motor provides reliable operation in demanding environments.
The rotary screw design uses male and female rotors to maintain continuous airflow without the frequent start-stop cycling common with piston compressors. A swing-arm-mounted dryer moves away from the compressor cabinet to improve service access, making maintenance easier in tighter equipment rooms. The dual-belt drive uses wider B- and C-width belts to distribute load more effectively, reducing belt tension, vibration, and stress on the motor and compressor components during long operating cycles.
Designed for automotive repair facilities, production shops, manufacturing environments, and commercial garages that rely on compressed air every day. The digital controller provides operating information and maintenance alerts, while the automatic dual-timer drain removes tank moisture on a preset schedule to help protect air tools, piping, and finished work from water contamination.
Features
-
Continuous-Duty Rotary Screw Air End
Oil-injected male and female rotor design supports up to 100% duty cycle operation, delivering consistent 24 CFM airflow during extended run cycles.
-
Integrated 30 CFM Refrigerated Air Dryer
Removes moisture from compressed air before it reaches tools and air lines. A condenser fan circulates ambient air across the cooling coil for efficient operation.
-
Swing-Arm Dryer Mount
The dryer pivots away from the compressor cabinet to improve access during maintenance and service.
-
Dual-Belt Drive System
Uses wider B- and C-width belts to distribute load across a larger surface area, reducing belt tension, vibration, and stress on motor and compressor bearings for longer drive life.
-
Dual-Timer Electric Auto Drain
Automatically removes condensate with adjustable 1–45 minute drain cycles and customizable open duration. Includes an air muffler for quieter discharge.
-
Fixed-Speed Operation
Maintains a constant 1750 RPM motor speed during operation for simple, predictable performance.
-
TEFC Motor
Totally enclosed fan-cooled three-phase motor designed for reliable operation in demanding shop environments.

Warranty
The compressor and integrated dryer include a 1-year standard warranty from the date of delivery, covering defects in materials and workmanship, plus 1 year of warranty labor from an authorized technician. Compressor coverage includes the rotary screw pump, electric motor, and system components. EMAX covers ground freight on warranty parts for the first 180 days; after that, warranty-part freight is the owner’s responsibility.
Extended coverage is available through EMAX warranty programs, which require enrollment and compliance with the recommended maintenance schedule, including EMAX SMART OIL auto-ship and filter replacement requirements. The extended compressor plan provides up to 10 years of coverage on the rotary screw pump and three-phase motor, with other components covered for up to 5 years. A Limited Lifetime pump warranty option is also available. The refrigerated dryer warranty can be extended up to 3 years through its own maintenance plan.
FAQ
What electrical service does it need?
The unit requires 208–230V three-phase power with a 21.6A full-load draw (1.15 service factor), 132A locked-rotor starting current, and a recommended 30A branch breaker. Confirm three-phase power availability before installation.
Can it run continuously?
Yes. The oil-injected rotary screw air end is rated for 100% duty cycle operation, allowing continuous airflow without the cycling associated with piston compressors.
Does it include an air dryer?
Yes. The package includes a 30 CFM refrigerated air dryer mounted on a swing arm for easier service access. The dryer removes moisture before compressed air reaches the shop air system.
What maintenance does it need?
The unit ships with break-in oil and filters that should be replaced at 600 hours, then maintained according to the EMAX service schedule. Following the SMART OIL program and required maintenance is necessary to maintain extended and lifetime warranty coverage.
How does it install?
The compressor requires three-phase electrical service and professional installation. It ships by freight and should be installed according to local electrical and equipment requirements.
