The EMAX 50HP Variable Speed Industrial Rotary Screw Compressor (Model: ERV0500003D-460) is built for high-demand industrial facilities, manufacturing plants, fabrication shops, and automated production lines operating on 460V 3-Phase power. This cabinet-only rotary screw compressor delivers 235 CFM at 100 PSI with a maximum pressure of 167 PSI, providing reliable compressed air for continuous industrial operation.

Unlike traditional reciprocating compressors, the rotary screw air end operates on a 100% continuous duty cycle, supplying consistent, pulse-free airflow without requiring cooling periods or causing pressure fluctuations.

Its integrated Variable Speed Drive (VSD) automatically adjusts motor speed to match real-time air demand. Instead of running at full speed continuously, the compressor produces only the airflow required, helping reduce energy consumption by up to 35%, lowering operating costs, minimizing component wear, and eliminating high inrush starting currents.

The heavy-duty powder-coated steel cabinet features integrated acoustic insulation for quiet operation between 62-65 dBA, allowing installation closer to production areas without requiring a separate compressor room. A precision-engineered rotary screw air end is rated for an estimated 100,000-hour service life, providing dependable long-term performance.
