Atlas Copco Element Mounting Kit GA5–10 Replacement – 2901057100

The Atlas Copco 2901057100 is an Element Mounting Kit designed for GA5–10 oil-injected screw compressors. It provides the required sealing and mounting components for correctly installing the compressor element and maintaining a secure, leak-tight connection.

The compressor element is the air end where the screw rotors compress incoming air. Proper mounting is important to maintain alignment, sealing and reliable operation.

Working Process

1. Air Intake – Atmospheric air enters the compressor through the inlet system.
2. Oil Injection – Oil is introduced into the compression chamber for cooling, lubrication and sealing.
3. Rotor Compression – The screw rotors compress the incoming air.
4. Element Mounting – The mounting hardware securely positions the compressor element.
5. Sealing – Gaskets and sealing washers prevent air and oil leakage at connection points.
6. Power Transmission – Correct mounting allows the drive system to rotate the compressor element properly.
7. Continuous Compression – The correctly installed element continuously produces compressed air.
