The air inlet and capacity control system utilizes electrical and pneumatic components to ensure the
compressor effectively produces compressed air to meet the demand of the customer’s process. This
control system is comprised of the inlet valve, and pressure transducers . Depending on air demand from the
customer’s process, these control components will cycle the compressor between four conditions: start-up,
full-load, unload, and shutdown.
