Atlas Copco Element Mounting Kit Replacement – 2901201300

The Atlas Copco 2901201300 is an Element Mounting Kit used for servicing and correctly mounting the compressor element in the C111 compressor. The kit contains mounting and sealing components, including a key and O-rings, which help secure the element and maintain proper sealing.

During compressor operation, the compressor element rotates and compresses air. Correct mounting and alignment of the element are essential to maintain efficient compression, minimize vibration and prevent compressed-air leakage.

Working Process

1. Air Intake – Air enters the compressor through the inlet system.
2. Element Rotation – The compressor element rotates and draws air into the compression chamber.
3. Air Compression – The element compresses the incoming air.
4. Mounting Support – The mounting components keep the element correctly positioned.
5. Alignment – Proper mounting maintains the required alignment of the rotating assembly.
6. Sealing – O-rings provide sealing between mating components and help prevent air leakage.
7. Power Transmission – The drive system transfers rotational power to the compressor element.
8. Compressed-Air Delivery – The compressed air exits toward the downstream system.
9. Continuous Operation – Correct mounting allows the element to operate reliably throughout the compressor’s operating cycle.

Main Functions

• Provides mounting components for the C111 compressor element.
• Maintains correct element positioning.
• Supports proper shaft/element alignment.
• Provides sealing through replacement O-rings.
• Helps prevent compressed-air leakage.
• Supports smooth and reliable compressor operation.
• Helps reduce vibration caused by incorrect mounting.

Kit Components

Available parts references identify 2901201300 as an Element Mounting Kit – C111. A shipment description specifically indicates the kit contains one key and O-rings.

Possible Failure Symptoms

Worn or incorrectly installed mounting components may contribute to:

• Air leakage.

3. Fully depressurize the compressor.
4. Allow the compressor to cool.
5. Remove the required connections and access components.
6. Remove the existing compressor element as specified in the service manual.
7. Inspect the mounting surfaces and drive components.
8. Clean the mating surfaces.
9. Replace worn mounting and sealing components with those supplied in 2901201300.
10. Install the key correctly.
11. Install the O-rings without twisting or damaging them.
12. Position and align the compressor element correctly.
13. Tighten the mounting components according to the applicable Atlas Copco specifications.
14. Reconnect the air and drive connections.
15. Restart the compressor.
16. Check for air leakage, abnormal vibration and unusual noise.
17. Verify normal operating pressure and temperature.
