The stop and start system is best employed where:

The stop and start system is particularly effective in scenarios where the air demand is low and infrequent. This is because the system is designed to operate intermittently, meaning it can turn on to meet the demand when necessary and then shut off during idle times.

When air demand is low, maintaining a continuous operating pressure with a constantly running system can be inefficient and waste energy. By using a stop and start system, power is conserved since the compressor only runs when air is actually needed. This also reduces wear and tear on the equipment, as it minimizes the number of hours the compressor operates.

In contrast, a scenario where air demand is constant would require a continuous operation to ensure that air supply meets the ongoing needs. Similarly, a large AC motor or a diesel engine as drivers would be more suited to different operational methodologies to handle varying loads more effectively rather than the stop and start approach, which is tailored for low and intermittent demand scenarios.
