Atlas Copco Element Exchange Installation Kit Replacement – 2906097100

The Atlas Copco 2906097100 is a service kit used when exchanging the compressor element. It contains the required O-rings, gasket, seal washer, screw and parallel key needed to correctly install and seal the replacement element.

The kit helps restore proper mechanical assembly and leak-free connections after an element replacement. Atlas Copco lists the kit weight at approximately 376 g.

Working Process

1. Air Compression – The compressor element compresses incoming air and generates pressure and heat.
2. Element Operation – The compressor element operates continuously under mechanical load.
3. Service Requirement – When the element reaches its service limit or requires replacement, the old element is removed.
4. Preparation – The mounting surfaces, shaft and connected piping are inspected and cleaned.
5. Seal Replacement – New O-rings and the gasket supplied in 2906097100 replace the old sealing components.
6. Mechanical Assembly – The parallel key and screw are installed to secure the replacement element.
7. Sealing – The new seals prevent oil and compressed-air leakage around the serviced connections.
8. Reassembly – The replacement compressor element is correctly positioned and connected.
9. Testing – The compressor is restarted and checked for leakage, vibration, temperature and performance.
