CAGI Compressed Air Specialist Practice Exam

The inlet valve is fully open in a load/no load capacity control compressor when the compressor is making all the air it can. This state indicates that the compressor is operating at its maximum capacity, delivering the highest volume of compressed air possible based on the demand from the system. In this scenario, the inlet valve must be fully open to allow unrestricted airflow into the compressor, ensuring that it can produce the necessary air volume to meet peak operational needs.

When the inlet valve is fully open, the compressor is engaged in its load phase, producing the required air pressure and flow. This condition is essential for achieving optimal efficiency and performance, as partial flow through the valve would restrict air supply and reduce the compressor's ability to deliver the required air volume.

The other scenarios presented involve conditions where either the compressor is not producing maximum output or is not under operational load, indicating that the valve would not be in a fully open position.
