Atlas Copco Element Mounting Kit GA15–30 VSD Replacement – 2901195800

Atlas Copco 2901195800 – Element Mounting Kit GA15–30 VSD

The Atlas Copco 2901195800 (2901-1958-00) is an Element Mounting Kit designed for applicable GA15–30 VSD oil-injected screw compressors. It provides the required mounting and sealing components for correctly installing and servicing the compressor element. Atlas Copco lists the kit weight as 105.233 g.

Working Process:

The compressor element is the main compression assembly where the incoming air is compressed by the rotating screw rotors. During operation, the element is subjected to pressure, temperature, vibration and oil circulation.

The element must remain securely mounted and its connection points must be properly sealed. Any leakage at the mounting interface can result in loss of compressed air, oil leakage or incorrect compressor operation.

The 2901195800 Element Mounting Kit supplies replacement mounting and sealing components used when the compressor element is installed or serviced.

During maintenance, the old gaskets and O-rings are removed and the applicable sealing surfaces are cleaned. The new components from the kit are installed at their specified locations before the element is reassembled.

Once correctly mounted and sealed, the compressor element can operate while maintaining the required integrity of the air, oil and control connections.

Main Functions:

• Supports compressor-element installation.
• Provides replacement mounting components.
• Restores sealing at element connections.
• Helps prevent compressed-air leakage.
• Helps prevent oil leakage.
• Maintains pressure integrity.
• Supports correct element positioning.
• Helps ensure reliable compressor operation.
• Supports maintenance of GA15–30 VSD compressors.

Element Mounting Working Cycle:

1. The compressor element is positioned in its designated mounting location.
2. The element mounting component is installed.
3. Required gaskets and O-rings are positioned at the specified sealing interfaces.
4. The element and associated connections are secured.
5. The sealing components prevent air and oil from escaping through the joints.
6. During operation, the screw element compresses incoming air.
7. Oil circulates through the compression and cooling circuit.
8. The mounting and sealing system maintains the integrity of the element assembly.
9. The compressor continues operating under pressure and vibration.

Role of O-Rings:

The O-rings provide sealing between the applicable mating components.

The 264 × 3, 12.3 × 2.4 and 32.2 × 3 O-rings are designed for their respective locations within the element mounting assembly.

O-rings can deteriorate due to:

• Temperature cycling
• Pressure fluctuations
• Oil exposure
• Vibration
• Ageing
• Compression set
• Incorrect installation

A damaged O-ring can result in oil or air leakage.

Role of Gaskets:

The gaskets provide sealing between applicable flat mating surfaces.

When the element is correctly assembled, the gasket is compressed between the mating surfaces and prevents unwanted leakage.

Reusing an old gasket after element removal can compromise sealing because the gasket may have already developed compression set or surface deformation.

Possible Failure Conditions:

Element mounting and sealing can deteriorate because of:

• Reuse of old seals.
• Damaged O-rings.
• Hardened or cracked seals.
• Incorrect gasket installation.
• Improper tightening.
• Damaged mating surfaces.
• Compressor vibration.
• Thermal cycling.
• Incorrect element alignment.

Possible symptoms include:

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

Maintenance Procedure:

Before servicing the element, shut down the compressor according to the applicable Atlas Copco maintenance procedure.

Isolate the electrical supply and depressurize the compressor.

Allow the compressor and oil system to cool to a safe service temperature.

Remove the applicable element mounting connections.

Inspect the mounting area for:

• Oil leakage.
• Air leakage.
• Damaged seals.
• Damaged gaskets.
• Corrosion.
• Contamination.
• Scratched sealing surfaces.
• Incorrect alignment.

Remove the old sealing components.

Clean all applicable mating and sealing surfaces.

Install the new components supplied in the 2901195800 Element Mounting Kit.

Ensure:

• Each O-ring is installed in the correct location.
• O-rings are not twisted or pinched.
• Gaskets are correctly positioned.
• Sealing surfaces are clean.
• The element is correctly aligned.
• Mounting components are properly secured.

Tighten all connections according to the applicable Atlas Copco service procedure.

After assembly, inspect the complete mounting arrangement.

Restart the compressor and allow it to reach normal operating conditions.

Check for:

• Oil leakage.
• Air leakage.
• Abnormal vibration.
• Pressure instability.
• Abnormal temperature.
• Unusual noise.
• Alarm conditions.

Service Benefits:

Using the 2901195800 Element Mounting Kit during appropriate maintenance helps:

• Restore element sealing.
• Maintain secure element mounting.
• Reduce oil and compressed-air leakage.
• Maintain pressure integrity.
• Support efficient compressor operation.
• Improve compressor reliability.
• Reduce maintenance-related downtime.
• Protect the compressor element and surrounding components.
