Advanced Low-Pressure Screw Element
Advanced asymmetric rotor profile design delivers high air flow with low energy consumption.
Equal-diameter rotor design gives the male and female rotors similar rigidity, improving overall structural strength.
The air end is specially designed for low-pressure applications, eliminating over-compression and improving energy efficiency.
High-Efficiency Motor
High-efficiency IE3 motor with Class F insulation and Class B temperature rise ensures reliable operation even in harsh environments.
SKF bearings ensure an exceptionally long motor service life.
A phase-sequence protector is included as standard to effectively prevent reverse motor rotation.
Larger High-Efficiency Oil-Air Separation System
Reduced system pressure drop effectively lowers energy consumption.
Oil content is below 2 ppm, helping reduce oil consumption and maintenance costs while extending service life.
Pre-Filter
Intake air filtration effectively protects internal components and extends product service life.
Easy to remove and reinstall, and reusable.
Heavy-Duty Filter
Removes 99.9% of coarse dust particles, providing excellent protection for compressor components.
Extra-large dust-holding capacity allows longer maintenance intervals.
Oversized Oil Cooler and Aftercooler
Lower rotor outlet temperature extends oil service life.
Eliminates thermal shock in the heat exchanger.
Reduced system pressure drop lowers energy consumption.
Integrated Variable Speed Drive
Fast control response with a speed regulation range of 30–100%.
The integrated variable speed drive features a compact design for easy maintenance.
