The idea
Essential information is needed to identify what the sentence refers to, and it takes no commas.
In practice
"Faculty who teach auto mechanics requested new equipment." Only those faculty made the request, so the clause narrows the meaning.
Where people slip
Commas around essential information change the claim, here making it about all faculty.
