Oil-free Screw Air Blower is a high-performance product designed specifically for applications that require clean and oil-free compressed air. It is widely used in industries such as electronics, pharmaceuticals, food and beverage, and wastewater treatment.
The blower features an oil-free screw design that eliminates the need for lubrication, ensuring a clean and uncontaminated compressed air supply. This makes it suitable for applications where oil contamination is not acceptable, such as in sensitive production processes or environments that require strict air quality standards.
The oil-free screw technology efficiently compresses air while minimizing energy loss. This results in energy savings and reduced operating costs. The blower is equipped with an advanced control system that optimizes performance and energy efficiency, maintaining stable air pressure and providing a consistent flow of oil-free compressed air.
The Air End
· Jointly developed oil-free twin-screw rotor with Hitachi
· High-efficiency asynchronous motor
· Direct drive, energy-saving, more robust stability
· Adopt the world-famous brand FAG bearing to ensure its reliability
· Unique lubrication and oil discharge channels ensure that bearings and gears get good lubrication and cooling while improving the efficiency of the main engine
· Advanced QPQ deep nitriding coating technology makes the rotor clearance smaller, enhances the volume efficiency at the same time, but also effectively protects the rotor, longer life
· Labyrinth seal and spiral seal assemblies ensure oil-free air to Class Zero
· Bearings adapt to changing loads and provide a high degree of flexibility and efficiency
Developed Oil – Free Twin – Screw Rotor With Hitachi
• Adopt 4-6 tooth rotor, the diameter of male and female rotor is basically the same, rotor strength is high, not easy to deformation, higher reliability
• Using the fourth-generation screw compressor rotor profile, bilateral asymmetric profile, fluid power loss is lower, the main engine efficiency is better
• Excellent line design technology, strictly control the size of the leakage triangle and the length of the contact line, to ensure that the rotor has good air tightness, reduce leakage and repeated compression, so that the main engine better energy efficiency
Rotor coating comparison
UCS：
• QPQ deep nitriding coating technology, physicochemical combination of coating technology
• Thin coating, chemical reaction with the base material, not easy to fall off, often used in automobile engine moving parts wear resistant coating
• Coating hardness is high, HRC72 above, can resist the impact of hard particles in the air for a
long time without falling off
• Good corrosion resistance, generally resistant to neutral salt spray test more than 500h
• High temperature resistance, coating preparation temperature 560°C, will not make the coating failure due to high temperature
Rotor Thermal Compensation Technology
3D Thermal Compensation Technology
• The inlet temperature is low, and the thermal deformation is small. The exhaust temperature is high, and the thermal deformation is large
• If the hot state has the same gap, the cold state gets bigger
• With thermal deformation automatic compensation function to reduce clearance leakage, maintain sealing
Heat Bilges Cold Shrink
The principle of thermal expansion and cold contraction, the inlet end temperature is low, the exhaust end temperature can reach more than 110℃, large deformation

Oil-free Screw Blower Work Principle
4 → 1 (figure 1-2 on the right), the suction process. With the rotation of the spiral rotor, the volume of the spiral groove increases gradually, and the air is sucked into the blower. Until the intake is closed.
1 → 2 (Figure 3 on the right), internal compression process. The suction port has been closed, but the exhaust port has not been opened. Due to the spiral design, the volume of the closed spiral groove is smaller and smaller due to the rotating movement, resulting in internal compression and pressure rise.
2 → 3 (Figure 4 on the right), exhaust process. As the rotor continues to rotate, the exhaust port opens and the air, which has been compressed, is discharged from the main engine.
