Atlas Copco Element Mounting Kit Replacement – 2901350100

Atlas Copco  – Element Mounting Kit

The Atlas Copco 2901350100 (2901-3501-00) is an Element Mounting Kit designed for applicable stationary oil-injected screw compressors, particularly GA VSD configurations.

The kit contains the required sealing washers, gasket and mounting-related components used when servicing or reinstalling the compressor element. These components help maintain proper sealing and secure installation between the compressor element and its associated connections.

The official Atlas Copco catalog lists the kit weight as 40 g and identifies it for GA VSD stationary oil-injected compressors.

Working Process:

During normal compressor operation, the screw element compresses atmospheric air.

The compressor element is connected to several oil, air and control circuits. These connections must remain properly sealed and securely mounted because they operate under pressure and are exposed to vibration and temperature changes.

The mounting arrangement keeps the compressor element correctly positioned within the compressor assembly.

The sealing components supplied with the 2901350100 Element Mounting Kit prevent leakage at the applicable element connections.

During compressor servicing, the element may need to be removed and reinstalled. Reusing old sealing washers or gaskets can result in leakage because these components may become compressed, hardened or damaged during previous operation.

The service kit provides new sealing components so that the element can be reassembled with reliable sealing.

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

Main Functions:

• Supports compressor-element mounting and servicing.
• Provides replacement sealing components.
• Helps maintain leak-tight element connections.
• Helps prevent oil leakage.
• Helps prevent compressed-air leakage.
• Supports correct element installation.
• Maintains pressure integrity.
• Supports reliable compressor operation.
• Helps reduce maintenance-related downtime.

Element Mounting Operating Principle:

1. Element Installation: The compressor element is positioned in its designated mounting location.
2. Connection Alignment: Oil, air and control connections are aligned with the element.
3. Gasket Installation: The applicable element gaskets are positioned at their designated joints.
4. Sealing: Seal washers provide leak-tight sealing at applicable connections.
5. Mounting: The element is securely mounted to the compressor assembly.
6. Compression Operation: The element compresses incoming air.
7. Oil Circulation: Compressor oil circulates through the element and associated oil circuit.
8. Pressure Containment: The installed seals prevent unwanted leakage.
9. Continuous Operation: The element operates under pressure, temperature and vibration.

Role of the Element Gasket:

The Unloader-Element gaskets provide sealing between the applicable compressor element and unloader connection.

The gasket prevents air or control pressure from escaping through the joint.

Over time, gaskets can experience:

• Compression set.
• Hardening.
• Thermal ageing.
• Cracking.
• Surface damage.
• Loss of sealing ability.

Replacing them during element servicing restores the sealing condition of the connection.

Role of Seal Washer M32:

The M32 seal washer provides sealing at its designated connection.

When the connection is tightened correctly, the washer forms a sealing barrier between the mating surfaces.

A damaged or reused washer may not provide reliable sealing after reassembly.

Role of M10 Washer:

The M10 washer provides the required mechanical/sealing support at its designated mounting point.

Correct installation ensures proper seating of the associated fastening connection.

Role of Dowty Seal Washers:

The 1/2+ Dowty seal washers provide sealing at the applicable threaded connections.

The elastomer sealing element creates the sealing interface while the metal portion provides mechanical support.

These washers help prevent leakage from pressurized oil or air connections.

Possible Failure Conditions:

Element mounting and sealing performance can deteriorate because of:

• Reuse of old gaskets.
• Reuse of sealing washers.
• Incorrect tightening.
• Over-tightening.
• Under-tightening.
• Damaged sealing surfaces.
• Vibration.
• Thermal cycling.
• Oil exposure.
• Incorrect assembly.
• Misalignment.

Possible symptoms include:

• Oil leakage around the compressor element.
• Compressed-air leakage.
• Control-air leakage.
• Pressure loss.
• Oil contamination around connections.
• Increased compressor energy consumption.
• Reduced compressor performance.
• Abnormal operating conditions.

Maintenance Procedure:

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

Isolate the electrical supply.

Depressurize the compressor and relevant air/oil circuits.

Allow hot components to cool to a safe working temperature.

Remove the applicable element connections and mounting hardware.

Inspect:

• Element mounting surfaces.
• Gasket surfaces.
• Seal washers.
• Threaded connections.
• Fasteners.
• Oil connections.
• Air/control connections.
• Signs of leakage.
• Signs of vibration or movement.

Remove the old gaskets and sealing washers.

Clean all mating and sealing surfaces.

Install the replacement components from the 2901350100 Element Mounting Kit.

Ensure:

• Gaskets are correctly positioned.
• Seal washers are installed at their designated connections.
• Washers are not damaged.
• Sealing surfaces are clean.
• Connections are correctly aligned.
• The compressor element is properly seated.
• Fasteners are tightened according to the applicable Atlas Copco service procedure.

After assembly, inspect all serviced connections.

Restore the oil and air circuits.

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

Check for:

• Oil leakage.
• Air leakage.
• Control-air leakage.
• Abnormal vibration.
• Pressure instability.
• Abnormal temperature.
• Alarm conditions.
