The EMAX 7.5HP Variable Speed Industrial Rotary Screw Compressor (ERV0070001) delivers 29 CFM at 100 PSI (maximum 145 PSI) from a standard 230V single-phase power supply. Designed as a cabinet-only system, it provides reliable, pulse-free compressed air with a 100% continuous duty cycle, making it ideal for automotive workshops, fabrication facilities, woodworking shops, and CNC operations.

Its integrated Variable Speed Drive (VSD) automatically adjusts motor speed to match air demand, reducing energy consumption by up to 35%, minimising start-up current, and extending component life. The sound-insulated steel cabinet operates at just 62–65 dBA, allowing installation close to work areas without the need for a separate compressor room.

Built with a premium rotary screw air end rated for an estimated 100,000-hour service life, this compressor delivers dependable long-term performance while integrating easily with existing receiver tanks and compressed air systems.
