Why choose Kobelco oil-free air compressors?

In modern manufacturing, compressed air contaminated with oil can cause:

• Product contamination
• Damaged terminal equipment
• Violation of safety and quality standards.

Kobelco Emeraude VF-VE air compressor the problem was completely solved thanks to:

• Do not use oil in the compressor chamber.
• The output compressed air absolutely clean, stable
• Meets stringent manufacturing standards.

Kobelco's oil-free screw compressor technology

The Emeraude VF-VE series uses oil-free screw technology advanced:

• High-precision machined screw assembly
• Avoid metal-to-metal contact.
• Reduce friction, reduce heat generation.
• Increase compressor head lifespan

As a result, the machine achieves high efficiency and maintains stable air quality throughout its operating life.

VF-VE Inverter: Energy Optimization

VF (Variable Frequency) & VE (Variable Energy) allow the machine:

• Adjust speed according to actual load.
• Reduce power consumption when the load is low.
• Limit idle running.

Particularly effective with systems that have compressed air demand fluctuates.

Key advantages of the Kobelco Emeraude FE-VF-VE oil-free air compressor. 

Outstanding energy savings

The single-stage Kobelco Emeraude FE-VF-VE utilizes a two-stage compression technology combined with an inverter.this significantly reduces overall power consumption during operation.

• Two-stage compression lifting overall performance is 8–28% higher. compared to conventional single-stage oil-free screw compressors
• The inverter automatically adjusts the motor speed according to actual air demand.
• Reduce power consumption when operating at low load.
• Maintaining stable pressure minimizes energy waste.

Why do two-stage compression systems help save electricity?

• The gas after the first compression stage is cooled through an intermediate heat exchanger → reducing the gas temperature before entering the second compression stage.
• Lower compression ratio per stage → reduced gas leakage in the compression chamber
• Reducing the load on the motor → increasing equipment lifespan.

Absolutely clean compressed air – Class 0 certified.

Kobelco oil-free air compressors are specifically designed to provide 100% clean, oil-free compressed air, meeting the stringent requirements of industries such as electronics, food, pharmaceuticals, and healthcare.
