Affortable variable frequency Screw Air Compressor: 

---frequency converter
Every model has a corresponding frequency conversion compressor, which controls the air flow by changing the rotational speed of motor, making the air output and electricity consumption smoothly vary synchronously with the different air flow. When the air use quantity falls, the air supply decreases and so does the electricity consumption for energy conservation. 

---Long Life of air compressor
Rotors are asymmetric in profile, backed up by ball bearings and roller bearings; Operate at a low speed, thereby low in abrasion and maintenance expenses, air end are long service life. Helical gears can produce axial force to kill some acting force, which reduces the load of the bearing of air end. 

---More reliable operation
With frequency conversion soft start, it avoids grid impact, self-engendered mechanical impact, and negative factors of lasting high speed operation of the air end. Without the participation of a contactor, it prevents point contact failure. Setting desired pressure at discretion, and maintaining constant pressure Users can set pressure between 3-14 bars at their discretion, without changing the gear of belt. 

---High Efficiency and energy saving
Thanks to the variable speed control technology, the capacity of compressors can be perfectly combined with the air use of users, which downright avoids the unloading power loss. In intermittent air use, the zero load of soft start avoids the peak of current and torque.
