Atlas Copco Hour Maintenance Kit Replacement – 2906080900

The Atlas Copco 2906080900 is an 8,000-hour maintenance kit designed for MD1000/1300W air-treatment equipment. The kit contains multiple replacement sealing, filtration, cooling and wear components required during major scheduled maintenance. Atlas Copco identifies it as an MD1000-1300W 8000H Maintenance Kit.

The purpose of the kit is to restore the condition of critical service components after extended operation, helping maintain proper air treatment, condensate management, sealing and equipment reliability.

Working Process

1. Compressed-Air Treatment – Compressed air enters the MD air-treatment system.
2. Cooling/Condensation – Air is cooled, causing moisture to condense.
3. Condensate Management – The system separates and drains accumulated condensate.
4. Air Separation – Internal components such as demisters and separators help remove moisture or contaminants.
5. Sealing – Gaskets, O-rings and sealing rings maintain pressure-tight connections.
6. Flow Control – Strainers and internal components maintain proper flow through the equipment.
7. Continuous Operation – The equipment provides treated compressed air to the downstream system.
8. Scheduled Maintenance – At the specified service interval, worn components are replaced using the 2906080900 kit.

Main Functions

• Provides components for 8,000-hour scheduled maintenance.
• Maintains effective air-treatment performance.
• Replaces worn sealing components.
• Supports condensate/moisture separation.
• Maintains proper flow through the equipment.
• Helps prevent air and fluid leakage.
• Restores the condition of wear components.
• Supports reliable long-term operation.
