By 2020, Gardner Denver and Ingersoll Rand officially merged, formed world's leading corporation in the field air compressors, vacuum pumps, blowers, and industrial equipment, ushering in a new era of global compressed air scale, technology, and solutions.

Overview of Ingersoll Rand Oil-Lubricated Screw Air Compressors RS series 

Gardner Denver – Ingersoll Rand group is a global corporation with over 150 years of experience in the field. air compressors and industrial equipment. The Nano central oxygen RS Series is one of the company's flagship oil-lubricated screw air compressor lines, notable for:

• High durability
• Stable performance
• Ability to operate continuously in harsh environments

Wide power range from 30 to 355 kW helps the RS Series meet a diverse range of needs, from medium-sized factories to large-scale industrial parks.

Why are RS Series the preferred choice for many factories?

In practice, businesses often encounter:

• Air pressure is unstable under heavy load.
• High electricity costs
• Compressors degrade quickly if run continuously.

RS Series addresses these problems by:

• Optimized screw design
• Efficient lubrication and cooling system
• Ability to work continuously 24/7

Oil-lubricated screw technology – The foundation of durability

RS Series air compressors use Oil-Injected Screw Technology, in which oil plays the role of:

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

As a result, the machine achieved:

• High compressor head lifespan
• Long-term stability
• Reasonable maintenance costs

Principle of operation

• Air is drawn into the screw assembly.
• The gas-oil mixture is compressed at high pressure.
• The oil is separated through a high-performance oil separator
• Clean compressed air is supplied to the system, and the oil is recirculated.

→ Closed-loop process – stable performance – safe operation
