Screw Compressor
Elite Air’s EA Series screw air compressors are designed to meet diverse industrial demands, offering a comprehensive range of power options for applications ranging from light-duty to heavy-duty. This series combines robust structural design with advanced intelligent control technology, ensuring superior reliability and operational efficiency even in demanding manufacturing environments.
To meet the stringent requirements of modern industry for energy conservation and cost reduction, the entire EA series now offers an optional “Variable Speed Drive (VSD)” function. Through advanced VSD technology, the compressor precisely adjusts motor speed according to actual air demand, eliminating the energy consumption typically associated with unloaded operation in fixed-speed machines. This not only achieves significant energy savings but also provides more stable system pressure and reduces impact on the power grid through soft starts, ultimately extending equipment lifespan.
Every EA series compressor (whether standard fixed speed or VSD equipped) is paired with high-efficiency motors and sophisticated microcomputer controllers. These provide real-time operation monitoring and multiple safety protections, making the EA Series the most trusted foundation for enhancing your facility’s productivity.
