The EMAX 40HP Variable Speed Industrial Rotary Screw Compressor (ERV0400003D-208) delivers 188 CFM at 100 PSI (maximum 145 PSI) for demanding industrial applications. Designed as a cabinet-only system for 208V 3-phase power, it provides a 100% continuous duty cycle, making it ideal for manufacturing plants, fabrication facilities, and automated production lines requiring reliable compressed air around the clock.

Its integrated 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 spikes. The heavy-duty sound-insulated steel enclosure keeps operating noise to just 62–65 dBA, allowing installation close to production areas without a dedicated compressor room.

At its core is a premium rotary screw air end engineered for an impressive 100,000-hour service life, delivering dependable long-term performance with minimal maintenance.
