Powerex SEQ4007 – 40 HP Oil-Less Scroll Enclosed Air Compressor

Eight 5 HP Pumps • Ultra-Quiet • Oil-Free

The Powerex SEQ4007 40 HP Oil-Less Scroll Enclosed Air Compressor is a high-capacity multiplex compressed air system engineered for facilities that demand exceptional airflow, maximum redundancy, clean air delivery, and quiet operation. Featuring eight 5 HP oil-free scroll compressor pumps, the SEQ4007 delivers powerful, reliable performance while maintaining low sound levels compared to traditional large-horsepower compressor systems.

The multiplex architecture allows the system to stage compressors on demand, optimizing energy efficiency and reducing wear. Built-in redundancy ensures uninterrupted operation. If one pump is offline, the remaining pumps continue supplying air, making the SEQ4007 an ideal solution for mission-critical environments where uptime is essential.

Housed in a sound-attenuated enclosure, this system is designed for three-phase power and allows customers to select standard 116 PSI or high-pressure 145 PSI operation to meet system requirements.
