Atlas Copco IMD300 8000H Maintenance Kit Replacement – 2906074900

Atlas Copco 2906074900 – IMD300 8000H Maintenance Kit

The Atlas Copco 2906074900 (2906-0749-00) IMD300 8000H Maintenance Kit is a preventive-maintenance service kit designed for compatible stationary oil-free Atlas Copco compressors, including ZR, ZT and ZW compressor systems. The kit is intended for maintenance intervals of up to 8,000 operating hours or 2 years, depending on the applicable maintenance schedule. Atlas Copco lists the official kit weight as 869 g.

Working Process:

The IMD300 system is associated with the compressor’s oil-free air-treatment and moisture-removal arrangement. During compressor operation, the system is exposed to continuous airflow, pressure changes, moisture, temperature variations, vibration and normal component wear.

The 2906074900 maintenance kit provides the replacement components required to restore important wear, inspection, sealing, filtration and moisture-removal functions during the scheduled maintenance interval.

The kit includes an IMD300 Rotor Inspection Kit, Demister MD200-400, O-ring, Strainer MD100/2500, and Set of Wearing Parts – 2 pcs. Atlas Copco’s official product listing confirms these components.

The IMD300 Rotor Inspection Kit is used during scheduled inspection of the applicable rotor assembly. Inspection of the rotor and associated components helps identify wear, contamination, damage or abnormal operating conditions before they develop into major equipment problems.

The Demister MD200-400 helps remove entrained moisture or liquid droplets from the associated air stream. By capturing liquid droplets, the demister helps protect downstream components and maintain the intended quality and performance of the compressed-air system.

The Strainer MD100/2500 provides filtration of unwanted particles and contaminants from the applicable flow path. Keeping the strainer clean and in good condition helps maintain proper flow and reduces the possibility of blockage or contamination reaching sensitive components.

The O-ring provides sealing between mating components. A properly functioning O-ring prevents leakage and maintains the required pressure and flow conditions within the assembly.

The set of wearing parts contains components intended for replacement during the scheduled maintenance operation. Replacing wear components at the prescribed interval helps maintain correct clearances, movement and mechanical performance.

During normal operation, contaminants, moisture and mechanical wear gradually affect service components. If maintenance is delayed, a restricted strainer or deteriorated demister can reduce system performance. Damaged sealing components may cause leakage, while worn mechanical components can affect the reliability of the associated assembly.

The 8,000-hour maintenance interval is therefore intended to restore the condition of these components before excessive wear or contamination affects compressor reliability.

Maintenance Procedure:

Before carrying out maintenance, the compressor must be stopped, isolated from all energy sources, completely depressurized and allowed to cool according to the applicable Atlas Copco safety procedure.

The maintenance technician should inspect the IMD300 assembly and associated components for contamination, wear, corrosion, leakage, deformation and abnormal deposits.

The IMD300 Rotor Inspection Kit should be used to perform the required rotor inspection.

The existing Demister MD200-400 should be inspected and replaced when required by the maintenance procedure.

The Strainer MD100/2500 should be inspected for blockage and contamination and replaced or serviced as specified.

The supplied O-ring should be installed on clean mating surfaces. The sealing surface must be free from damage, contamination and debris. The O-ring should not be twisted, cut or overstretched during installation.

The supplied wearing parts should be installed in the correct positions and orientations according to the applicable Atlas Copco service instructions.

After reassembly, all covers, connections and sealing points should be checked for correct installation.

The compressor should then be restarted according to the manufacturer’s procedure and monitored for abnormal vibration, leakage, pressure behavior, temperature, airflow and other operating conditions.

Correct maintenance of the IMD300 system helps maintain the performance of the oil-free compressor, protect associated components from contamination and moisture, maintain reliable sealing, and reduce the risk of unexpected downtime.

Using the Atlas Copco 2906074900 IMD300 8000H Maintenance Kit at the prescribed maintenance interval helps restore the condition of critical service components and supports reliable compressor operation over the next service period.
