EMAX 7.5 HP Single-Phase Rotary Screw Air Compressor with 120-Gallon Tank & 30 CFM Refrigerated Dryer (ERIK070001)

The EMAX ERIK070001 is an all-in-one 7.5 HP single-phase rotary screw air compressor built for shops that need steady, continuous airflow without the heat and downtime of a reciprocating pump. The rotary screw air end, a 120-gallon horizontal air receiver tank, and an integrated 30 CFM refrigerated air dryer arrive as one factory-assembled package, pre-plumbed with connecting hoses and ready to wire in.

Oil-injected rotary screw air ends are engineered for up to 100% duty cycle, so the ERIK070001 can run load after load where a piston compressor would need to cool down. The result is consistent, steady air for plants, production lines, and busy service bays. A dual-timer electric auto drain clears moisture from the tank automatically, while the integrated refrigerated dryer pulls humidity out of the compressed air before it reaches your tools and lines.

Power is delivered through a multi-belt V-belt drive, and the swing-arm dryer mount lets the dryer hinge away from the cabinet for service access. The unit requires 230V single-phase service on a 40-amp breaker (28.8 full-load amps including service factor) — confirm your shop's supply before ordering.

This package ships via freight with an uncrated weight of 660 lbs. To schedule delivery or confirm site requirements, contact MGS at sales@mygaragesupplies.com or 307-381-1810.

• Rotary screw air end — oil-injected male and female rotor design rated for up to 100% duty cycle, delivering continuous, steady airflow with relatively quiet operation.
• Integrated 30 CFM refrigerated air dryer — a condenser and cooling fan remove moisture from the compressed air to protect tools, lines, and finishes.
• Dual-timer electric auto drain — automatically expels water from the receiver tank on an adjustable 1- to 45-minute cycle, with a settable open duration and an included air muffler for quieter discharge.
• Swing-arm dryer mount — the dryer hinges away from the compressor cabinet to open up room for maintenance and service.
• Multi-belt V-belt drive — wider B- and C-width belts spread the load across more surface area, reducing belt tension and strain on the motor and compressor bearings while lowering noise and vibration for longer drive life.
• Fixed-speed operation — the motor runs at a constant 1750 RPM during run cycles for predictable, simple performance.
• 120-gallon horizontal tank — a large air reserve that smooths demand across tools and equipment.

The ERIK070001 rotary screw compressor carries a 1-year standard warranty covering defects in materials and workmanship — including the rotary screw pump and electric motor — plus one year of warranty labor from an authorized technician.

Coverage can be extended through EMAX's extended-warranty and SMART OIL auto-ship maintenance programs: up to 10 years on the rotary screw pump and 5 years on the single-phase motor, and a limited lifetime warranty on the pump for owners enrolled in the auto-ship program. The integrated refrigerated air dryer carries a 1-year standard warranty, extendable to 3 years. Extended and lifetime coverage require enrollment and adherence to EMAX's maintenance schedule; full terms are in the warranty documents below.

What electrical service does the ERIK070001 require?

It runs on 230V single-phase power and draws 28.8 full-load amps (including a 1.15 service factor), so EMAX specifies a 40-amp breaker.

Does it include an air dryer?

Yes. A 30 CFM refrigerated air dryer is integrated into the package and removes moisture from the compressed air before it reaches your tools and lines.

Can it run continuously?

The oil-injected rotary screw air end is rated for up to 100% duty cycle, so it is built to run load after load rather than cycling on and off like a piston compressor.

What maintenance does it need?

EMAX ships the unit with break-in oil and filters that are changed at 600 hours, then on the EMAX maintenance schedule (annually or every 4,000 hours). The recommended service kit is SKIT001AWB, and using EMAX SMART OIL is required to keep extended or lifetime warranty coverage in force.
