The EMAX 20HP Fixed Speed Industrial Rotary Screw Compressor (Model: ERI0200003-208) is a high-volume pneumatic workhorse engineered specifically for major manufacturing complexes, automated assembly plants, and heavy-duty facilities operating on low-voltage 208V 3-Phase power grids. Designed as a space-saving "Cabinet Only" standalone module, this heavy commercial engine delivers an immense, non-surging 76 CFM at 100 PSI (and 68 CFM at its max 145 PSI). Traditional multi-piston configurations attempting to match this massive volume generate destructive amounts of friction heat, requiring strict duty cycle limitations to avoid structural failure. Conversely, this industrial rotary air end thrives under a 100% continuous duty cycle, running smoothly 24/7/365 under maximum plant tool loads without ever risking thermal shutdown or line starvation.

Running high-horsepower machinery in localized floor spaces typically creates a deafening roar and intense floor vibrations. EMAX completely solves this layout issue with its premium, heavy-gauge steel sound attenuation enclosure cabinet. Operating at a whisper-quiet 62 to 65 dBA, this system produces less noise than a standard household conversation, allowing you to bypass building an isolated compressor house and place the unit directly inside your active workspace cells. At its mechanical heart is an oversized, precision-ground single-stage rotary screw air end rated for an industry-leading 60,000-hour commercial pump lifecycle, ensuring decades of trouble-free operation.

Driven by a high-efficiency, premium-insulated 20HP electric motor paired with a heavy-duty, fixed-speed direct belt-drive assembly, this standalone cabinet configuration packs massive pneumatic output into a compact physical footprint. It represents the ultimate infrastructure upgrade for automated fabrication yards, large multi-booth commercial collision networks, precision CNC machine loops, and high-speed packaging lines looking to transition away from high-maintenance piston hardware.

Key Features

Why Choose the EMAX ERI0200003-208 Rotary Screw Compressor?

  • True 100% Continuous Duty Cycle: Built to run around the clock under relentless pneumatic demand. While reciprocating compressors must cycle off to cool down, this industrial rotary air end operates constantly without drop-offs, keeping automated lines running.
  • Enormous 76 CFM Volume Output: Supplies a steady, continuous column of high-volume compressed air capable of running multiple sandblasting bays, high-speed multi-axis CNC machines, and heavy production machinery simultaneously.
  • Low-Voltage 208V 3-Phase Optimization: Engineered explicitly to draw power cleanly from standard 208V three-phase electrical systems, avoiding the need for costly high-voltage step-up utility upgrades while maintaining balance across your facility's power legs.
  • Elite 60,000-Hour Pump Life: The industrial air end relies on precision-machined asymmetric male and female helical rotors turning on high-load roller bearings. With no metal-to-metal wearing contacts, it outlasts standard reciprocating pump designs by up to 300%.
  • Ultra-Quiet Sound Enclosure Cabinet: Insulated cabinet panels isolate internal mechanical resonance, dropping active operation sound down to 62–65 dBA. This protects employee hearing and ensures seamless compliance with strict OSHA noise workplace regulations.
  • Versatile "Cabinet Only" Plumbing Integration: Built as a standalone unit without an attached storage tank, this cabinet fits flexibly into existing air loops. Line it directly into large vertical bulk receiver tanks, external refrigerated air dryers, or primary facility manifold systems.

    Frequently Asked Questions

    Do I need to buy a separate air receiver storage tank to use this machine?
    Yes. Because this model is a "Cabinet Only" standalone unit, it features no internal air storage tank. Rotary screw compressors require an external receiver tank to damp out facility pipeline system spikes and give downstream water moisture a localized place to drop out. You can cleanly plumb this cabinet outlet line into any existing vertical or horizontal air storage tank (typically 120 gallons or larger is ideal for a 15HP unit).


    Why does a rotary screw air end last so much longer than a standard piston compressor pump?
    Standard piston pumps rely on pistons moving vertically inside cylinders, which creates constant friction, extreme heat cycles, and inevitable wrist-pin/ring wear. Rotary screws utilize two interlocking helical screws that compress air smoothly in a continuous fluid-sealed rotating motion without matching surfaces ever banging or rubbing together. This friction-free geometry yields an exceptional 60,000-hour operational life.


    Can this 208V unit be re-wired to run on a 460V or 230V three-phase panel?
    No. This specific model variation is engineered and optimized explicitly for low-voltage 208V 3-Phase electrical grids. Attempting to feed it alternate voltages will cause severe current imbalances and permanent motor damage. If your plant runs on a different industrial voltage grid, you must select the corresponding voltage-configured variant from the EMAX lineup.
