For about $300.

Is 1.2 SCFM @ 90 PSI enough for decent usage?


You need to check the tools you use to see what they are rated as
needing.

For nailers probably, any other air tool probably not.

polisher 15 cfm @ 90psi
orbital sander 4 CFM @ 90 PSI
angle grinder 3 CFM @ 90 PSI small
air saw for 16 gauge 4 CFM @ 90 PSI
18 gage nailer 0.5 CFM @ 90 PSI
framing nailer 3 CFM @ 90 PSI
1/2" impact gun 6 CFM @ 90 PSI

Just to give you some of the items.

In order for specific air flow to be measured in SCFM, most experts
agree that the air flow must meet the following set of rigid
environmental circumstances;

The air temperature must be 68 degrees Fahrenheit
The relative humidity of the air must be 36%
The air itself must be measured at sea level

As far as I know basic cfm is what it says at the PSI it was rated as.

So that sort of takes us back to my original question. The DeWalt battery
compressor is rated in SCFM (1.2 SCFM @ 90 PSI) as is my PC compressor
(2.6 SCFM @ 90 PSI)

Since the DW is rated at less than half my PC, where do you think the $300
1.2 SCFM unit would "fail" (i.e. not be up to the task at hand) but the
$99 PC would handle with ease?

Based on your list of items, are you saying that the only tool that *either*
compressor will operate is the 18 gauge nailer?

At home the pancake on similar to your will do about 7 framing nails
and will not drive any more all the way home until it fills back up.

Finishing nails and staples seem to go enough longer that I have to
change positions anyhow and the compressor can catch up.

If these pressure switches would have and adjustable differential I
could tweak it so that I could drive a few more nail, but the
differential is fixed and to buy a good one costs over half of a cheap
compressor.

It is a source of irritation to be but if you spend a grand on a good
system you can't drag the sucker around.

You might want to consider battery operated nailers, staplers, etc.
they won't require the waiting cycles. Use the compressor to blow off
the work bench and fill tires etc.

If you go battery operated tool just be sure to get one compatible
with the tools you already have.
