according to wiki
Compressors can be classified according to the pressure delivered:

Low-pressure air compressors (LPACs), which have a discharge pressure of 150 psi or less

Medium-pressure compressors which have a discharge pressure of 151 psi to 1,000 psi

High-pressure air compressors (HPACs), which have a discharge pressure above 1,000 psi[2]

They can also be classified according to the design and principle of operation:

Single-Stage Reciprocating Compressor

Two-Stage Reciprocating Compressor

Compound Compressor

Rotary-screw compressor

Rotary Vane Compressor

Scroll Compressor

Turbo compressor

Centrifugal compressor
