In the construction and operation of nuclear power plants, compressed air serves not only as a vital power source but also plays a critical role in instrumentation, pneumatic valves, and sealing systems. To ensure safety and operational stability, the purity and reliability of compressed air are crucial. Any trace of oil or contaminants may lead to valve malfunctions, sensor drift, or even compromise system safety.
Therefore, oil-free air compressors have become the ideal choice for air supply in the nuclear industry, while the rental model brings additional flexibility and cost efficiency.
Ⅰ. Clean Air Supply: The Silent Guardian of Nuclear Operations
Nuclear power facilities demand air systems that are clean, stable, and continuous. If oil mist, particles, or moisture are not properly controlled, they may accumulate over time and disrupt the precision of sensitive components.
Oil-free air compressors, with their lubricant-free compression design, deliver air that meets ISO 8573-1 Class 0 standards—providing a clean and reliable source of air for control and instrumentation systems.

Ⅱ. Rental Solutions: Flexibility Under High Standards
The demand for equipment in nuclear projects varies by phase. Choosing an oil-free air compressor rental plan effectively addresses challenges such as temporary air demand, large capital investment, and equipment management.
- Flexible Configuration: Adjust the number of compressors based on project stage and air demand, minimizing idle time and waste.
- Cost Optimization: Avoid large one-time procurement expenses and reduce life-cycle costs.
- Rapid Deployment: Standardized equipment can be delivered and installed quickly, shortening construction and commissioning periods.
- Professional Support: Full-cycle technical service from the rental provider ensures stable and continuous operation.
FOOEN has developed mature “Equipment + Service” rental solutions across multiple nuclear testing and expansion projects—covering equipment selection, system design, on-site deployment, and technical maintenance in one integrated process.

Ⅲ. Technical Advantages: Oil-Free Compression for Safe Operations
The nuclear industry primarily employs oil-free screw and oil-free centrifugal compressors, both offering key advantages:
- Clean Air Output: 100% oil-free compression ensures air quality meets the strictest standards.
- High Reliability: Dual-stage compression, efficient cooling, and intelligent control enable long-term stable operation.
- Low Dew Point Control: Combined with refrigeration or desiccant dryers, outlet dew points can reach -40°C to -70°C, preventing condensation and corrosion.
- Smart Control System: Multi-unit parallel operation and remote monitoring ensure pressure stability and energy efficiency.
These features meet the nuclear sector’s stringent requirements for zero contamination and maximum reliability, reflecting the depth and dependability of professional rental services.
Ⅳ. Typical Applications: From System Purging to Instrument Air Supply
Oil-free air compressors are widely applied across various nuclear project phases, including:
- System purging and moisture removal
- Pneumatic valve and actuator testing
- Instrument and control air supply
- Nitrogen generation pre-treatment
- Containment leak testing
In one of FOOEN’ nuclear testing projects, multiple ES Series oil-free air compressors were deployed in parallel with desiccant dryers and precision filters. The system continuously delivered low-dew-point, oil-free compressed air, supporting critical pressure and safety tests with stable, high-quality performance.

Conclusion: Defining Safety with Oil-Free Technology, Empowering the Future with Rental Solutions
The nuclear industry demands the highest safety and reliability standards. FOOEN’ oil-free air compressor rental service—combining flexibility, dependability, and cost efficiency—provides secure and clean air supply for nuclear projects.
As nuclear technology continues to advance, oil-free air compressor rental is becoming a key solution that balances both safety and efficiency in the industry’s sustainable development.
