I can see why larger compressors, which would suit a production shop
and beg for distribution, might have no regulators, but I can't see
why smaller ones wouldn't come with them unless reeeeeeeally cheap.
You got it. Save a buck to be more competitive. I'm not sure where you
draw the line, but my PC pancake has a regulator and I never run more than
one tool. If I had distribution, I'd rather have the regulation closer to
the tool. this is common practice to assure adequate air at the point of
FWIW, I picked up a $20 inline regulator at Coastal, added quick
connects, and plug it in right at the tool. I leave the compressor @
105-110 PSI, and adjust at the tool.
It's really a handy setup and well worth the $20.
I sometimes run a 15g finish nailer and a 18g brad nailer for the same
assembly. I regulate at the compressor to what the 15 wants, then ad a
T and regulate one leg with an inline regulator to what the 18 wants.
easy and cheap to set up, works great.

I use it on everything, as I'm too lazy to walk back to the
compressor. <G> If I'm out of the shop, there's a good chance that
the compressor may not even be on the same floor. Usually it's in a
basement or garage, and I'm too floors up!
Yes there may be an adjustment in the pressure switch. If you take the cover
off of it there will be a nut or screw with a spring under it, backing off
the screw will lower the pressure. That said, the switch adjustment is
probably welded so you can not adjust it, my Porter Cable compressor is! If
you need to get the discharge pressure lower buy a air regulator.

That's the pressure limit switch. Air pressure opens and closes the
switch to the motor depending upon high and low pressures. Most decent
compressors also have a built-in unloader which permits the motor to
start the compressor with no pressure in the compressor head.
There are usually 2 screw controls in a pressure switch, one for high
cutoff, the other for low pressure re-engage.
Generally, the pressure switches are adjusted downward by rotating the
screw counterclockwise. If it were mine, I'd unplug it, pop the
plastic cover off, loosen the locknut, adjust the HI screw (they're
usually marked) 1/4 turn counterclockwise, retighten the locknut.
Then I'd run air pressure in the tank down to about 80 psi, plug it
back in, turn it on, and look at both pressures, high and low, for the
results. I'd then proceed from there, knowing the correct direction to
P.S: Play with this at your own risk. If you're not comfy doing it,
take the compressor down to most any auto or compressor mechanic and
give him a few bucks to adjust it for you.
