Atlas Copco Inlet Box Kit C106 Replacement – 2200900950

Atlas Copco 2200900950 – Inlet Box Kit C106

The Atlas Copco 2200900950 Inlet Box Kit C106 is a replacement valve/inlet control kit used in an oil-injected screw compressor. The inlet box assembly regulates and controls the flow of atmospheric air entering the compressor air-end during the compression cycle.

Working Process:
When the compressor starts, the inlet system controls the amount of air allowed to enter the compressor element. As the compressor operates, the inlet valve responds to the compressor’s operating conditions and regulates the incoming airflow according to the required air demand. During loaded operation, the inlet passage opens progressively to allow sufficient air into the compressor element for compression. When the required pressure is reached or the compressor unloads, the inlet mechanism reduces or restricts airflow, helping to maintain the required system pressure and prevent unnecessary energy consumption.

The 2200900950 inlet box kit works as part of the compressor’s inlet/control system to provide smooth and controlled airflow. It helps the compressor transition correctly between loaded and unloaded conditions, supports stable pressure regulation, and reduces the possibility of excessive air intake during unloaded operation.

During maintenance, the kit can be replaced when internal valve components, seals, or related parts become worn or damaged. Proper installation helps restore the inlet system’s sealing and control function, supporting reliable compressor performance, efficient operation, and consistent compressed-air delivery.
