Brand New Screw Rotors

* An asymmetric rotor profile is adopted, and both the first and second rotors are with 4-6 teeth. The unique structure can be easily matched with different models.

* The rotors are made of high-strength alloy steel. Both the male and female rotors and the inside of the casing are all coated with PTFE+MoS2 to prevent corrosion and improve the sealing performance.

* High efficiency and low energy consumption.


High Strength and Low Wear Bearings

* Both the inlet and discharge ends adopt the original imported SKF ball bearings & back-to-back tapered roller bearings, which are suitable for different load operations.

* Good stability with no need for pre-lubrication or running-in period.


Running Time Guaranteed

* Increases running time and reduces system energy consumption. The airend shutdowns at 350° C, and the coating is heat-resistant up to 350°C.
