Sandblaster 100 feet from compressor
 

I came across a smallish sized Trinco sandblaster today (24 inch
wide with front door only), with dust collector.

I am considering putting it into a shed, which is roughly 100 feet
(100 ft hose run) from the compressor. Maybe it is a little more than
100 feet.

My question is, if I run air at higher pressure like 120-140 PSI, and
drop it near the blaster to 60-80 PSI, would I be able to get away
with 3/8" ID hose, or is that not sufficient.

Perhaps run full compressor pressure (175?) out there to an accumulator
tank (sure you can scrounge something) then regulate off that tank to
your final pressure. Should do the job since I don't expect you'll be
doing very long durations of blasting without stopping to reposition
parts, etc.

no way. if I had to run 100 feet, I'd use at least 3/4 inch galvanized -
pipe is cheap, and the long run will help cool the air

Sandblasters are air hogs. Your pressure drop will be excessive.

You can do a quick test: coil up the 100' of hose on the floor, hook up
the gun only with a pressure gage on a 'T' at the gun(no sand, no
cabinet), see what pressure you get out of it.

I can tell you that something like an air cutoff tool will run fine on
my smaller compressor when I have a 25' hose running from the tank to
the gun, starts then stalls when I run the same rig through 50' of 1/2"
copper tube to the garage.
