Atlas Copco LP Element Exchange / Removal Kit Replacement – 2906010800

The Atlas Copco 2906010800 LP Element Removal Kit is a service kit designed for maintenance and removal/exchange of the low-pressure (LP) compressor element in applicable oil-free compressors.

The LP element performs the first stage of compression. During major servicing, the element must be safely removed and replaced while maintaining proper sealing of the compressor connections. The kit supplies the required gaskets, O-rings and sealing components for the service operation. Atlas Copco lists the kit weight at approximately 600.1 g.

Working Process

1. Air Intake – Atmospheric air enters the LP compressor element.
2. First-Stage Compression – The LP element compresses the incoming air.
3. Intercooling – Partially compressed air is cooled before the next compression stage.
4. Service Removal – When the LP element requires replacement, the compressor is isolated and the element is removed.
5. Seal Replacement – The worn gaskets and O-rings are replaced using components from 2906010800.
6. Element Installation – The replacement LP element is correctly positioned and aligned.
7. Leak Prevention – New seals provide tight connections and help prevent compressed-air leakage.
8. Restart – After reassembly, the compressor is restarted and checked for leakage and proper operation.
