I have a single-stage 2 HP, 8 gallon Central Pneumatic air
compressor that I've supe'ed up.
The pump normally turns on at 80 PSI and then shuts off at 115 PSI.
Problem is, at 80 PSI (before it turns on again), my nail guns don't
drive the nails flush. I need it to have a consistent minimum 100 PSI
going through it.
I have increased the pressure switch so that it now goes from 100
PSI cut-on and then 135 PSI shut off. I know that it will likely
reduce the life of my compressor in the long run, but does anyone know
how much difference a 20% increase in pressure reduces the working
life of a pump? I only use it for a few hours a year, so the
compressor doesn't get a lot of regular stress put on it. Plus, it's
not too expensive, so I can just buy another one. So this is more of
an educational question.
I've heard that all 2 HP (and up) pumps (single and 2 stage) are
capable to doing more than 115 PSI. Maybe the 2 stage can do it with
more CFM and with a longer pump life.
Also, I'm thinking about connecting it in series with a separate 10
gal. air tank, so that I can have a total working capacity of 18 gal
Is this too abusive to be doing to my poor 2 HP motor? In theory,
if I let it have several minutes of rest and cool-downs between engine
cycles, it should be ok, right?
