Overall Performance

* Reliable and durable: The structure conforms to the physical design and protects the unit from high temperature, vibration, or other conditions that may cause damage to it.

* Excellent energy efficiency ratio. The motor drives two sets of rotors based on lever principle.

* High efficiency PM variable frequency synchronous motor; two-stage compression with large discharge volume.


Sullivan-Palatek Screw Airend

* Imported from the USA, with 5-year warranty.

* New Sullivan-Palatek Air End, moreaccurate, durable, and efficient.

* SKF B-10 bearings imported from Germany, with a designed service life of 100,000+ hours.

* Heavy-duty and thickened airend housing ensures low noise, low vibration, and longer operating life.


PM(Permanent Magnet) Motor

* IE4, with superior efficiency and excellent energy saving performance.

* The unit is designed to ensure the durability of the PM motor.

- Embedded permanent-magnet structure improves the motor's shock resistance and prevents the PM motor from losing magnetism due to long-term vibration.

- Adopt IV-grade magnetic steel material which can withstand temperature up to 180so as to prevent the PM motor from losing magnetism due to high temperature.


Carbon reduction and energy saving

* Eliminates energy waste from loading or unloading of standard industrial frequency units.

* Saves energy more than 6% with high efficiency IE4 PM frequency conversion motor.


PLC Intelligent Control System

* Microcomputer control system for intelligent andefficient operation.

* Centralized control-to remote monitor and control multi machines (include different brands and different equipment).

* Multi languages in operating system.
