Major electrical components are sourced from internationally recognized brands such as Schneider Electric. The wiring is neatly arranged, with clearly organized circuits to help minimize electrical interference and avoid wiring-related obstructions. This structured layout also simplifies future adjustments, troubleshooting, and maintenance.
The screw air end features large rotors and a low-speed design, delivering low noise, reduced vibration, a low compression ratio, high volumetric efficiency, and a long service life.
The main drive motor is a high-efficiency permanent magnet motor with an IP55 protection rating. Its torque characteristics and bearing loads are specially engineered to optimize performance. Compared with conventional motors, it can improve energy conversion efficiency and power factor by 5%–8%, depending on operating conditions.
A high-efficiency inverter from a leading brand is integrated into the variable-speed drive system. By adjusting motor speed to match actual air demand, the system helps reduce energy consumption, improve operating efficiency, and optimize overall power utilization.
The intelligent control system features user-friendly operation, one-touch setting, and bilingual interface switching between Chinese and English. Its intuitive visual interface integrates intelligent monitoring and multifunctional control, making system operation simpler, more efficient, and easier to manage.
The system combines a specially designed vessel, a multi-stage oil-gas separation element, and an oil return device to ensure reliable separation performance and extended service life.
The high-density filter element is designed to maintain a stable airflow path during filtration, helping reduce unnecessary flow disturbance and providing better protection for the bearings and screw rotors.
