I just laid out the framework for a new wiki article on this topic: Choosing a compressor
; I know this is a common question here. The wiki article is currently just an organized list of headings and questions, but I'm sure it will be built gradually over time.
We do currently have an Air compressor silencer
article, and I just put in a good bit of work on our Media blasting
article, so this new article seems like a logical next step.
