Rotary-screw compressor

OverviewSizeWorkingHistoryApplicationsControl schemesSuperchargers

The capacities of rotary-screw compressors are typically rated in horsepower (HP), Standard Cubic Feet per Minute (SCFM)* and pounds per square inch gauge (PSIG.) For units in the 5 through 30 HP range the physical size of these units are comparable to a typical two-stage compressor. As horsepower increases, there is a substantial economy of scale in favor of the rotary-screw compressors. As an example, a 250 HP compound compressor is a large piece of equipment th
