Atlas Copco Element Mounting Kit – 2901353300

Atlas Copco 2901353300 – Element Mounting Kit

The 2901353300 (2901-3533-00) is an Element Mounting Kit used during installation, removal and servicing of the compressor element in applicable Atlas Copco screw compressors. The kit provides the required sealing and mounting components needed to correctly reinstall the compressor element and maintain leak-tight connections.

Working Process:

The compressor element is the main component where atmospheric air is compressed by the rotating screw rotors. During operation, the element is exposed to pressure, temperature, oil circulation and mechanical vibration.

The element must be securely mounted and its connection points properly sealed. During element servicing, old O-rings and gaskets can become compressed, hardened or damaged and may no longer provide reliable sealing.

The 2901353300 Element Mounting Kit is used to replace these sealing components during reassembly.

The available parts documentation lists the kit with:

• O-ring Ø49.5 × 3
• O-ring
• O-ring
• Gasket
• Instruction

The referenced documentation lists these components under 2901 3533 00 – Element mounting kit.

Main Functions

• Provides replacement components for compressor-element mounting.
• Restores sealing at element connections.
• Helps prevent oil leakage.
• Helps prevent compressed-air leakage.
• Maintains pressure integrity.
• Supports correct compressor-element installation.
• Helps maintain reliable compressor performance.
• Reduces the risk of leakage after element servicing.

Element Mounting Working Cycle

1. Compressor Shutdown: The compressor is isolated and depressurized before maintenance.
2. Element Removal: The compressor element is disconnected from its associated air and oil connections.
3. Inspection: Mounting and sealing surfaces are inspected for wear or damage.
4. Seal Replacement: Old O-rings and gaskets are removed.
5. Surface Cleaning: Mating surfaces are cleaned to remove oil, dirt and old sealing material.
6. Kit Installation: New sealing components from 2901353300 are installed.
7. Element Mounting: The compressor element is correctly positioned and secured.
8. Connection Sealing: The new seals prevent air and oil from escaping through the joints.
9. Compressor Operation: The screw element compresses air while the mounting assembly maintains the required pressure integrity.
10. Leak Inspection: After startup, the serviced area is checked for oil or air leakage.

Role of O-Rings and Gaskets

The O-rings create a tight seal between mating components. They prevent oil, compressed air or control air from passing through unintended gaps.

The gasket provides sealing between applicable flat mating surfaces.

These sealing components can deteriorate because of:

• High temperature
• Oil exposure
• Pressure cycling
• Vibration
• Ageing
• Compression set
• Incorrect installation
• Contamination

Possible Failure Symptoms

If the element mounting seals are damaged or incorrectly installed, the compressor may experience:

• Oil leakage around the element.
• Compressed-air leakage.
• Pressure loss.
• Oil contamination around connections.
• Increased compressor running time.
• Increased energy consumption.
• Reduced compressor efficiency.
• Abnormal compressor operation.

Maintenance Procedure

Before servicing the compressor element:

1. Shut down the compressor according to the applicable Atlas Copco procedure.
2. Isolate the electrical supply.
3. Fully depressurize the compressor.
4. Allow hot oil and components to cool.
5. Remove the relevant element connections.
6. Remove the old O-rings and gaskets.
7. Inspect the sealing surfaces.
8. Clean the mating surfaces.
9. Install the replacement components supplied with 2901353300.
10. Ensure O-rings are correctly seated and not twisted or pinched.
11. Position the gasket correctly.
12. Reinstall and align the compressor element.
13. Tighten all connections according to the applicable Atlas Copco service procedure.
14. Restart the compressor.
15. Check for oil and air leakage.
16. Monitor pressure, temperature and vibration.

Service Benefits

Using the 2901353300 Element Mounting Kit during appropriate maintenance helps:

• Restore reliable element sealing.
• Prevent oil and compressed-air leakage.
• Maintain pressure integrity.
• Support correct element installation.
• Improve compressor reliability.
• Reduce energy losses caused by leakage.
• Reduce maintenance-related downtime.

Technical Summary

The 2901353300 identification as an Element Mounting Kit is supported by multiple parts references, including Atlas Copco compressor documentation.
