For medium and large-scale manufacturing plants, the compressed air system needs to meet multiple requirements simultaneously. high performance, high stability, and reasonable operating costs.. Ingersoll Rand R Series 55–75 kW Oil-lubricated Screw Air Compressors designed to work continuously 24/7, bringing superior compression performance, long-lasting durability, and significant energy savings, suitable for a wide range of industries.

Overview of the Ingersoll Rand R Series

Gardner Denver – Ingersoll Rand group is a global brand with over 150 years of experience in the industry industrial air compressors. The Nano central oxygen R Series developed as a solution comprehensive, flexible, and reliable for central compressed air systems.

With a power range 55–75 kW, the R Series is particularly suitable for:

• The factory operates in multiple shifts.
• Medium to high load compressed air systems
• Businesses need machines durable – stable – easy to maintain

Why are R Series 55–75 kW trusted by so many factories?

In practical operation, common types of compressed air systems include:

• Pressure fluctuates when the load changes.
• High power consumption when the machine runs at low load.
• Maintenance costs will increase if the design is not optimized.

Ingersoll Rand R Series effectively solves the problem thanks to:

• Screw design optimized for performance.
• Efficient cooling and lubrication system
• Ability to maintain stable pressure for extended periods

Oil-lubricated screw technology – The foundation for durable operation.

R Series uses Oil-Injected Screw Technology, in which oil plays important roles:

• Lubricate the screw shaft.
• Seal the compression chamber.
• Reduce friction and wear.
• Supports heat dissipation during air compression.

As a result, the machine achieved:

• High durability
• Long-term stable performance
• Reasonable maintenance costs

Principle of operation

• Ambient air is drawn into the screw assembly.
• The air is compressed along with the lubricating oil.
• The gas-oil mixture passes through a high-performance oil separator
• Clean compressed air is supplied to the system, and the oil is recirculated.

→ Closed-loop process – safe operation – stable performance

Optimized design for 24/7 operation.

The Ingersoll Rand R Series is designed to meet the demands of industrial environments:

• The frame is sturdy and can handle heavy loads.
• Soundproof enclosures help reduce noise.
• Maintenance departments are arranged in a logical manner.
• Easy to inspect and perform routine maintenance.

This design helps reduce downtime and increase compressed air system performance.
