1.A multi-functional electronic controller complete with LED display provides a convenient,user-friendly interface.
2.The certified machine is assembled with strict compliance to CE and ISO9001 standards.
3.We offer a one year warranty covering the entire machine and a three year standalone warranty for the air end.\
4.A modified voltage service is provided with the purchase of the machine to accommodate various power supply standards found in different countries.
5.The DeWATE compressor utilizes the original Atlas copco air end and the unique SAP corkscrew gear design to achieve the highest efficiency compression speed with minimal vibrations.
6.The DeWATE compressor air end implements the patented Atlas copco SAP,along with a fixed diameter rotor.In comparison with a low speed 5/6 teeth or 4/5 teeth connection,the negatively oriented rotor possesses higher integrity and greater speed.

DeWATE Double Corkscrew Compressor Diagran

The corkscrew air end is the heart of the corkscrew compressor,or so to speak.Its capabilities have a direct correlation with the economical use and operation of the machine.The DeWATE compressor utilizes the original Atlas copco air end and the unique SAP corkscrew gear design to achieve the highest efficiency compression speed with minimal vibrations.In combination with high precision SKF bearings,this greatly increases the service life of working parts.

High Quality DeWATE Compressor Air End Bearings
The SKF bearings provide a high degree of stability in the event of load changing and act to extend the service life of the rotor.The low operating speed of the bearing reduces friction caused wear while a low operating temperature reduces bearing load.All these combined factors guarantee a long service life for the high precision bearings.

Direct transmission has an application range in between DWT 75HP and 475HP,An improrted flexible coupling with original factory settings facilitates direct transmission,and in the proess,combines the motor and air end into a single working entity.The resulting transmission is reliable and highly efficient.

The DeWATE compressor air end implements the patented Atlas copco SAP,along with a fixed diameter rotor,In comparison with a low speed 5/6 teeth or 4/5 teeth connection,the negatively oriented rotor possesses higher integrity and greater speed.These qualities prevent rotor deformation and ensure minimal internal leakage.In addition to these features,the direct-drive model utilizes the patented Atlas copco corkscrew for a high precision grinding finish.


Motor and Air End Continuous Synchronization

The DWT series compressor successfully combines the motor,gearbox,and air end into a single functional machine.This design guarantees the continuous synchronization of the motor and air end during transport,installation,and normal operations.In addition,the direct-driven model is fitted with a high efficiency,fully closed IP54 motor.

Dual Language Chinese English LCE Display System
The control interface comes with system-wide performance status,
preemptive maintenancereminders,fault alarm and a safety shutdown.All detection and control functions can be found on the same interface with default Chinese display.This provides a broad spectrum of communicationpossibilities.The direct-driven model implements a highly versatile interface that can easily be incorporated into various industrial control systems.
