Compressors are sized based on what requirement?

Compressors are primarily sized based on the CFM, which stands for cubic feet per minute. This measurement indicates the volume of air or gas that the compressor can deliver over a specified period. Sizing based on CFM is essential because it ensures that the compressor can meet the specific demands of the system it is serving, whether it be for pneumatic equipment, HVAC systems, or other applications requiring a consistent flow of air or gas.

When selecting a compressor, understanding the required CFM allows operators to ensure that the compressor can provide adequate airflow to maintain performance without causing system strain or inefficiencies. Proper sizing helps avoid issues such as short cycling or inadequate pressure, which can lead to longer operational times and increased wear on the equipment.

In contrast, while other factors like PPM (parts per million) regarding contaminants, theoretical discharge temperatures, or the size of high-pressure receivers are relevant in specific contexts, they do not directly dictate the sizing of compressors. Instead, these elements may influence performance and operational efficiency after the appropriate CFM requirement has been established.
