Steady Air Output

Fixed speed operation delivers consistent air supply without fluctuations, making it ideal for applications with stable demand and continuous operating conditions.

Optimised Airend

Next‑generation screw elements reduce internal pressure losses, ensuring efficient compression and dependable air delivery across the full operating range.

Advanced Cooling

Separate oil and air coolers maintain stable operating temperatures, protecting components and supporting long-term performance in demanding environments.

Fixed speed compressors with stable output and robust design

The EKO 55-90 fixed speed range is designed for industrial sites with consistent compressed air demand, delivering reliable performance without the complexity of variable systems. Covering models from 55 to 90 kW, it provides stable output across standard pressure configurations, making it well suited for continuous production environments.

Performance and durability are built into the core design. Optimised screw elements reduce internal losses, while the casted oil separator vessel ensures efficient oil separation and low oil carryover. Separate oil and air coolers maintain thermal stability and extend component life, while heavy‑duty filtration protects internal parts and supports long operating intervals.

The EKO 55-90 fixed speed range includes compressors from 55 to 90 kW, available across standard industrial pressure levels up to 13 bar. The range delivers consistent air output suited to stable demand applications while maintaining efficient performance across different operating conditions.

All models feature low noise levels around 77–78 dB(A) and are designed according to ISO standards for performance measurement. The compressors combine robust construction with efficient air delivery, ensuring reliable operation in industrial installations.

Maintenance is designed to ensure easy access and long service intervals. Heavy‑duty air, oil and separator filters protect key components and help reduce the frequency of service interventions, contributing to lower operating costs over time.

Separate oil and air coolers are mounted for easy removal and cleaning, improving accessibility and simplifying service operations. The integrated minimum pressure valve supports reliable operation while reducing leakage risk, helping maintain consistent performance throughout the compressor lifecycle.

The fixed speed configuration provides a stable and efficient solution for applications with constant air demand, avoiding the added complexity of variable speed systems. This results in predictable operation and reliable performance for continuous industrial use.

Optional energy recovery allows the heat generated during compression to be reused for heating or process applications. This improves overall energy efficiency and supports lower operational costs across the installation.
