DREAM Centrifugal Air Compressors are designed for medium to large‑capacity industrial applications where oil‑free air, high efficiency, and long‑term reliability are critical. Based on advanced aerodynamic design and aerospace‑grade manufacturing technology, DREAM centrifugal compressors deliver stable, clean, and energy‑efficient compressed air solutions for modern industry.
They are widely used in new energy, chemical & petrochemical, electronics, textiles, brewing, laser cutting, pharmaceutical, and food industries, helping customers significantly reduce operating costs while improving production stability.
Why Choose a Centrifugal Compressor?
Compared with traditional oil‑injected screw compressors, centrifugal compressors are the preferred solution for large flow rates above 60 m³/min, especially when oil‑free air quality and continuous operation are required.
Key advantages:
100% oil‑free compression, no risk of oil contamination
Lower life‑cycle cost for large‑capacity systems
Higher reliability for continuous 24/7 operation
Cleaner air improves downstream equipment and product quality

High‑Efficiency Impeller
The impeller is the heart of a centrifugal compressor. DREAM uses aerospace‑grade titanium alloy impellers, manufactured by five‑axis precision machining.
**Impeller advantages:**
* Higher aerodynamic efficiency and lower flow loss
* Excellent corrosion resistance for special gases
* Higher allowable linear speed than stainless steel
* Stable operation under variable working conditions
* Long service life with minimal deformation risk filecite turn0file0
Air End & Rotor System
The air end adopts a **horizontally split structure**, making inspection and maintenance simple and efficient.
**Design features:**
* Thrust ring structure without thrust bearings
* High transmission efficiency and improved reliability
* Non‑contact labyrinth seals: zero wear, long service life
* Optimized diffuser design for maximum pressure recovery
* Surface‑hardened diffuser improves durability by up to 3× filecite turn0file0
