Market-leading performance
Oil-free screw drive system E-Series delivers class-leading performance while maintaining the renowned durability of Ingersoll Rand. Thanks to optimized air intake design and improved rotor configuration, overall performance is improved tới 13,5%, this simultaneously increases compressed air flow and significantly reduces energy consumption.
As a result, the business achieved:
- Higher airflow
- Long-term energy savings
- Reduce overall operating costs.
Why is it mandatory for large-scale factories to use oil-free air compressors?
On a large-scale production basis, the risk of oil contamination in compressed air not only causes product defects but also leads to:
- Mass production line shutdown
- The economic damage is enormous.
- Violation of international quality standards (ISO, GMP, HACCP, etc.)
- This seriously damages the company's reputation.
Ingersoll Rand E Series Oil-Free Screw Air Compressors Completely eliminate this risk through design do not use oil in the compression chamber, ensuring compressed air meets standards ISO 8573-1 Class 0 – the highest level of cleanliness..
Next-generation oil-free screw drive technology – The foundation of the E Series.
High-performance oil-free screw auger
- Do not use lubricating oil in the compression chamber.
- High-precision machining
- Special anti-wear coating
- Maintaining stable performance over the long term.
This design ensures:
- Compressed air 100% clean right from the source.
- Reduce downstream compressed air treatment costs.
- Increase the reliability of continuously operating systems.
