selecting the best compressor for a given application by comparing its capacity and the control methods and characteristics of available compressor models with the variation of compressed air consumption over time. This is an analysis aimed at selecting one or several compressors best suited to the optimal consumption in terms of its maximum, minimum and intermediate values. The assessment of the selection process should be based on the criterion of providing the appropriate stream, pressure and quality of compressed air to the point of consumption, with maximum reliability and minimum energy consumption. The sizes of compressors depend on the types of electric motors available on the market used to drive them. In the process of selecting a compressor, it is very important to pay attention to the quality of the compressed air network so that it is effective, tight and does not constitute a restriction in providing the expected parameters of the compressed air stream.
