While we are talking about air compressors, I've been doing some research
because I'm thinking of upgrading my compressor.
>From previous threads, it seems like most people on this list seem to
think 2 stage is the way to go because you can get high PSI (usually 175)
and CFM (around 15 for the compressors I've been looking at). I'm just not
really sure why I need 175 PSI? For about 1/3 to 1/2 the price of a 2
stage compressor, I can get a single stage compressor that will deliver up
to 16 CFM at 90 PSI. It seem slike most air tools only require 90 PSI, so
why do I need 175? I'm not trying to be cheap, just educated. Thanks.
