Again thanks to everyone. Mark mentions the harbor freight
compressor:<br><br>

<br><br>
Looking at it's basic specs, it is only rated at 4.5 SCFM @
90PSI. My compressor<br>
is rated at 9.3 SCFM @ 90 PSI. I've have used my compressor
for everything <br>
from painting cars, sanding, impact hammers, die grinders, and both media
blasting <br>
cabinets & pressure blasting. And I'm always running out of air
and stopping to let<br>
the compressor catch up.<br><br>
So that brings up more questions:<br><br>
1. What really controls how much a comperssor can generate, ie.
SCFM?<br><br>
2. What controls how long your compressor can supply air before having to
start <br>
the motor to refill the tank? I realize that some air tools use a
LOT more air, but<br>
I'm speaking for any given tool, not compairing something like spray
painting to <br>
undoing 5 lugnuts on a car. <br><br>
3. Why is a bigger tank better? After the compressor's pressure
switch kicks on, <br>
doesn't it take longer for the compressor to reach the shut off pressure
with a <br>
larger tank?<br><br>
4. How can a 1.7 hp compressor deliver a peek of 175 psi and a regulated
155 psi <br>
when my 5 hp can only charge to 125 psi. I realize part of that is
due to the <br>
pressure switch, mine is 110 on - 125 off, but really. Can I put a
pressure switch in mine and 175 psi. I don't really think
so. Is this more advertising hype like <br>
when they were rating compressors at their starting current vs running
current for <br>
hp? They could get 7hp of of a 110V motor - NOT!<br><br>
