Years ago HP = CFM. This meant bigger HP more CFM. Sales jerks
catch on quick, and had Tiwain junk make with big HP compressors
and junk pumps. So people were getting cheap, low output compressors,
with a good motor, and paying the big bucks. I am using one....
It is make (imported) by Snap on, and is a 5 HP. I also have a old 1 1/2
HP, compressor that will almost keep up with in, except the tank is to
small. What you want to look for, is the CFM rating. bigger the better.
If this is a one shot deal, there are people that do sandblasting
for industry, that you can hire. I had my 1936 chrysler done this way.
They will blast as little or as much as you want. MAke sure you
duct tape up anything that you don't want sand blasted that is close you
the rust.
You are asking alot to try to get a portable compressor to sand
blast. I would recomend a gas compressor if portablilty is what you
need. 110v would be pushing a 20 amp continuous draw, and be marginal
at best.
One last note. Sand blasting makes one hell of a mess. Sand is every
where, when your done. It is worse than a week at the beach with ten
dirty kids. A spot blaster requires less CFM, and makes less mess, but
is limited in it's ability. I have never tried one but this is the
way I would go if I had to do the last 20 years over.
