Since 1965, Sullair has designed and manufactured DS oil-free screw air compressors with core technology of screw rotors, and won the 2010 Industrial Product Award in the United States, providing customers worldwide with the highest quality and efficiency products, becoming a world leader in screw technology and vacuum technology.

1. The screw host is the core component developed by Sullair, and after three generations of development, it has become more mature and efficient:

2. Latest patented screw profile

3. Paired manufacturing of yin-yang screws with high manufacturing accuracy

4. By using special bearings, the faulty component of the balance piston has been eliminated

5. The high-pressure rotor is designed with 5-7 teeth for better sealing effect

6. High pressure rotor made of stainless steel material, suitable for harsh working conditions

7. FDA regulates food grade coatings for safe and reliable use

8. Craft labyrinth gas seal/oil seal, capable of compressing special gases

9. The newly developed third-generation DS oil-free screw host adopts three-dimensional fluid analysis theory in its design, optimizes the thermal balance design of the screw rotor sealing line, and optimizes the shape of the exhaust port to minimize internal leakage.
