The EMAX 50HP Variable Speed Industrial Rotary Screw Compressor (ERV0500003D-208) delivers 235 CFM at 100 PSI with a maximum pressure of 145 PSI, making it an excellent choice for manufacturing plants, fabrication facilities, and high-demand industrial operations. Designed as a cabinet-only system for 208V 3-phase power, 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%, minimising wear, and eliminating high start-up current. A heavy-duty sound-insulated steel enclosure keeps operating noise to just 62–65 dBA, allowing installation close to production areas. The premium rotary screw air end is engineered for an exceptional 100,000-hour service life, delivering dependable long-term performance.
