What a 20-40 Bar Catalogue Label Does and Does Not Tell You

The Drive sources explicitly identify CM_G and CM_GPV oil-free screw air-compressor families with a 20-40 bar label. That is a valid family-level catalogue boundary and can be used to organize medium-pressure platform references.

What it supports

It supports the existence of a source family described as 20-40 bar. It can also support the fixed-frequency versus variable-frequency family distinction when the source title says so.

What it does not support

It does not by itself establish the exact model, flow at the requested pressure, motor rating, ambient correction, oxygen-cleanliness level or oxygen-service suitability. Those fields require the actual source row and project-specific engineering review.
