EMAX 10 HP 120-Gallon Rotary Screw Air Compressor ERIK010001

The EMAX 10 HP rotary screw air compressor delivers 45 CFM at 100 PSI from a single-phase 230V power supply, eliminating the need for three-phase electrical service. Built with an oil-injected rotary screw air end, it supports up to a 100% duty cycle for continuous operation during demanding production schedules, with an estimated 60,000-hour service life. The system includes a 120-gallon horizontal receiver tank and an integrated refrigerated air dryer rated for 58 CFM, providing clean, dry compressed air before it reaches your equipment.

The integrated refrigerated dryer removes moisture from the air stream to help protect tools, air lines, and finished surfaces from water contamination. Its swing-arm mounting design allows the dryer to move away from the compressor cabinet for easier maintenance access, while the dual-timer electric auto drain automatically removes tank condensate with adjustable drain intervals from 1 to 45 minutes. The fixed-speed motor maintains a consistent 1,750 RPM throughout operation, delivering predictable performance without the added complexity of variable-speed controls.

Designed for professional shops, manufacturing environments, and high-demand automotive applications, this compressor is a strong fit for operations that require reliable compressed air throughout long work cycles. The multi-belt V-belt drive helps distribute load efficiently, reducing vibration, belt strain, and wear for dependable daily use.

Features

Oil-injected rotary screw air end

The oil-injected rotary screw air end uses matched male and female rotors to deliver smooth, continuous airflow without the pulsing typical of piston compressors. Designed for up to 100% duty cycle operation, it runs quietly and is built for long service life, with the air end rated for an estimated 60,000 hours and a maximum working pressure of 145 PSI.

Integrated refrigerated air dryer

The integrated refrigerated dryer is rated for up to 58 CFM and removes moisture from compressed air by cooling it until condensation forms and can be separated. A dedicated condenser fan moves ambient air across the dryer coil, helping release heat and keeping moisture from reaching tools, air lines, and finished surfaces.

Swing-arm dryer mount

The dryer is installed on a swing-arm mount that pivots away from the compressor cabinet, creating easier access for maintenance and inspections without requiring the dryer to be disconnected.

Dual-timer electric auto drain

The electric dual-timer auto drain automatically removes collected water from the receiver tank. Drain intervals can be adjusted from 1 to 45 minutes, while the open duration can also be customized to match operating conditions. An inline air muffler helps reduce discharge noise during draining.

Fixed-speed operation

The compressor uses a fixed-speed design that maintains a consistent 1,750 RPM during operation. This provides steady performance and reliable output while avoiding the added complexity and cost of variable-speed controls.

Multi-belt V-belt drive

The multi-belt V-belt drive uses wider B- and C-width belts to distribute load across a larger contact area, improving grip while reducing belt tension. This helps minimize stress on the motor and compressor bearings, while lowering vibration and noise for a durable, low-maintenance drive system designed for extended service life.

Specifications

Warranty

EMAX provides separate warranty coverage for the compressor and refrigerated dryer.

The rotary screw compressor includes a 1-year standard warranty against defects in materials and workmanship, covering the rotary screw pump and all major components, including the electric motor. The warranty also includes one year of labor coverage performed by an authorized technician. For the first 180 days, EMAX covers ground shipping on replacement parts.

Customers can extend coverage through EMAX’s SMART OIL maintenance program with two available warranty upgrades:

• Extended Warranty: Covers the rotary screw pump for up to 10 years, the single-phase motor for 5 years, and most other components for 5 years.
• Limited Lifetime Warranty: Provides non-prorated, unlimited-hour coverage for the rotary screw pump through the SMART OIL auto-ship program.

Both extended coverage options require the use of EMAX SMART OIL and approved filters according to the recommended maintenance schedule.

Refrigerated dryer warranty

The refrigerated dryer includes a 1-year standard warranty covering materials, workmanship, and parts, along with one year of warranty labor.

Coverage can be extended to 3 years by registering the dryer and purchasing one Airbase dryer filter replacement kit each year, while continuing to follow the required maintenance schedule.

FAQ

What electrical service does it need?

The compressor runs on 230V single-phase power and draws 38.3 full-load amps with a 1.15 service factor. EMAX recommends a 55-amp breaker for installation. Since it operates on single-phase power, no three-phase electrical service is required.

How does it remove moisture from the air?

The system uses two moisture-control methods. The integrated refrigerated dryer, rated for up to 58 CFM, cools compressed air to condense and remove moisture before it reaches downstream tools. The dual-timer electric auto drain then automatically releases collected condensate from the receiver tank to help prevent water buildup between uses.

Can it run continuously?

Yes. The oil-injected rotary screw air end is designed for up to 100% duty cycle operation and is rated for an estimated 60,000 hours of service life. It is built for demanding shop environments where compressed air is needed throughout the workday.

What maintenance and oil does it use?

The rotary screw pump holds 1.33 gallons of oil. Each unit includes factory break-in oil and filters, which should be replaced after the first 600 hours of operation. After that, EMAX recommends changing the oil and filters annually or every 4,000 hours, whichever comes first.

Maintaining the compressor with genuine EMAX SMART OIL and approved filters according to the recommended schedule is required to qualify for the extended warranty and limited lifetime warranty programs.

How does it ship?

The compressor ships by freight on a pallet. When crated, it weighs 1,455 lbs and measures 84 in L × 47 in W × 77 in H. A forklift or liftgate-equipped delivery truck is required for unloading. Contact MGS at support@carliftsupply.com or 877-600-5227 to arrange freight delivery.
