Atlas Copco IMD 300 Connection Kit Replacement

The Atlas Copco 2906074800 IMD 300 Connection Kit is a service kit used when servicing or removing the IMD300 dryer assembly from applicable ZT oil-free compressors. The kit provides the required sealing/connection components to disconnect and reconnect the IMD300 system while maintaining proper airtight connections.

The official Atlas Copco listing specifies a kit weight of approximately 181.4 g.

Working Process

1. Compressed-Air Generation – The oil-free compressor produces compressed air.
2. Drying Stage – Air passes through the integrated IMD300 dryer system.
3. Service Isolation – During maintenance, the IMD300 system is isolated and depressurized.
4. Connection Removal – Existing connections are opened to allow the IMD300 assembly to be serviced or slid out.
5. Seal Replacement – The sealing components supplied in 2906074800 are installed.
6. IMD300 Reconnection – The dryer assembly is reconnected using the replacement sealing components.
7. Leak Prevention – New gaskets/seals provide an airtight connection.
8. System Testing – After reassembly, the compressor and dryer are pressurized and checked for leakage and correct operation.
