How to determine whether to choose a centrifugal compressor or a reciprocating compressor based on basic parameters
Let me start by discussing pressure increase: those with a small pressure increase generally use centrifugal compressors, while those with a large pressure increase use reciprocating compressors. But it’s not absolute; more details are provided below
When the air flow rate is less than 3000 m3/h, centrifugal compressors are not suitable； Reciprocating compressors are suitable for applications with low flow rates and high outlet pressures ； For low-flow air compressors, screw compressors can be an option; for specific details, please consult the manufacturer.
Reciprocating compressors are suitable for low molecular weight, high pressure, and low flow rates

It mainly depends on the pressure ratio and flow rate:
Hello, may I ask what P/R means in the table?
