  • Relief valve

The independently designed unloading valve (Patent No.: ZL200520058468.2), specifically engineered for vortex characteristics, enables fully sealed operation in screw compressors, ensuring stepless air delivery from 0 to 100%.


250KW Direct-driven Water Cooling Oil-free Rotary Screw Compressor

  • Water cooler

The plates are made of special 304L stainless steel, offering corrosion resistance and high thermal efficiency, which reduces pressure and temperature differentials and ensures the system operates under near-isothermal compression. The system features a compact design, requires less cooling water, minimizes pressure loss, enhances durability, and is easy to clean and maintain.

AIRERA 250kW Screw Air Compressor: Frequently Asked Questions (FAQ)
How does AIRERA address wear and coating issues on oil-free screw aires?
AIRERA utilizes advanced high-performance rotor coating technology, which enhances corrosion resistance and minimizes operational clearances. Even after long-term operation, the coating maintains excellent sealing performance to ensure no airflow degradation and sustained high efficiency.
What are the core advantages of the 250kW model in food processing and electronics manufacturing?
Both industries have rigorous air purity requirements. AIRERA's 100% oil-free technology eliminates the risk of product oil contamination at the source, preventing costly recalls, while its pressure stability ensures the precision of sensitive pneumatic components and automated production lines.
Does the 250kW model have a high impact on the power grid during startup?

The model offers optional VFD soft-start technology, ensuring a smooth startup current without impacting the facility's power grid. This protects electrical components and avoids peak-demand penalties or voltage fluctuations caused by high startup inrush.
