HPDMC air compressors come in two types: single and two-stage. When it comes to buying a single-stage or dual-stage air compressor, the first question that buyers often ask is, “What are the differences between the two?”
The main difference is the number of times that air gets compressed between the inlet valve and the tool nozzle. In a single-stage compressor, the air is compressed one time; in a two-stage compressor, the air is compressed twice for double the pressure.
single-stage compressor has higher CFM but PSI only 100-125 usually
two-stage compressor has lower CFM but PSI reach 170-185
