The EMAX 40HP Variable Speed Industrial Rotary Screw Compressor (ERV0400003D-460) delivers 188 CFM at 100 PSI (maximum 145 PSI) for high-demand industrial facilities, manufacturing plants, and fabrication workshops operating on 460V 3-phase power. Designed as a cabinet-only system, it provides a 100% continuous duty cycle for reliable, uninterrupted compressed air.

Its advanced Variable Speed Drive (VSD) automatically adjusts motor speed to match air demand, reducing energy consumption by up to 35%, lowering operating costs, minimising component wear, and eliminating high start-up current. The 460V electrical configuration further improves efficiency by reducing running amperage.

The sound-insulated steel enclosure operates at just 62–65 dBA, allowing installation close to work areas without a dedicated compressor room. The premium rotary screw air end is engineered for an impressive 100,000-hour service life, delivering dependable long-term industrial performance.
