Variable speed rotary screw compressor

EKO 30-45 VST

The EKO 30-45 VST series delivers reliable and energy‑efficient compressed air for industrial applications with limited space. Covering 30 to 45 kW, these oil‑injected, direct‑drive rotary screw compressors combine compact design, quiet operation and variable speed control to support uninterrupted production and lower operating costs.

Energy Efficiency

Variable Speed Drive technology continuously adapts compressor output to air demand, reducing energy losses during both loaded and unloaded operation and lowering total cost of ownership.

Compact Design

The compact footprint and low noise level make the EKO 30-45 VST ideal for installations where space is tight, without compromising performance or service accessibility.

Smart Control

The ES4000 Graphic controller provides full access to operating parameters, supports multi‑compressor communication and enables intelligent load sharing, alerts and service planning.

Variable speed performance for demanding industrial applications

The EKO 30-45 VST range is engineered to deliver stable compressed air with high efficiency through oil‑injected, direct‑drive technology. Optimised rotor profiles and in‑house designed airend blocks reduce internal pressure losses, while the coupling‑free drive train minimises transmission losses and supports long duty cycles in demanding environments.

High‑capacity cooling, an expanded cooler surface and smart airflow design ensure reliable operation in ambient temperatures up to 46 °C. Integrated components such as the water separator and efficient oil management contribute to consistent air quality, reduced wear and dependable performance throughout the compressor’s lifetime.

EKO 30-45 CD VST

The EKO 30-45 VST series covers motor power from 30 to 45 kW and operates across a wide pressure range up to 13 bar. Free air delivery varies by model and pressure setting, allowing correct matching to application demand. Noise levels are measured in accordance with ISO 2151, supporting installation close to production areas where quiet operation is required.

The EKO 30-45 VST is designed for easy service and long equipment life. Key components are accessible for maintenance, and the direct‑drive concept reduces mechanical complexity. Continuous monitoring through the controller supports predictive maintenance, helping reduce unplanned downtime and maintain reliable operation over time.

With variable speed regulation, the EKO 30-45 VST significantly reduces energy consumption compared to fixed‑speed compressors. By adjusting output to real demand, energy losses are minimised and operating costs are reduced. Combined with durable construction, efficient cooling and long service intervals, this results in a lower total cost of ownership and improved production continuity.
