Hello folks,
I deleted the message about getting the two stage compressor over a single
stage compressor.
Maybe I missed something, but the important issue is with the air delivery rate
of the compressor.
A two stage has higher psi range (135 -175 psi) with 17 -100 free air cfm @ 175
psi. The free air
rating @90 psi would be greater. $1000 and up
A single stage has a maximum pressure range of 100 -135 psi with 2 to 17 free
air cfm @90 psi.
For a single stage to get the higher free air flow rating one has to go to a
larger tank capacity (ie
30 -60 gallons). $100 - 1000.
All of my air tools operate at 90 psi are less with a maximum of 9.0 cfm flow
rate. It would be overkill
to get a two stage compressor. I can't see an individual having a need for a
two stage compressor. If
one had a bussiness that relied on multiple air tools running at the same time
or everything in the bussiness was air powered, then a two stage would be
neccesary.
On the other hand the inside diameter size of the air hose used has a big
effect on air delivery. There are 1/4",
3/8", 1/2" and greater air hoses. The larger the inside diameter of the hose
the larger the air flow.
I believe that for $400- 500 or less can get you a single stage compressor with
a free flow rate of 10-11 cfm @ 90 psi that will work just fine.
Now for the disclaimer,
Portability is a limitation factor for higher cfm flow rate.
I do not have a sandblaster.
I just had surgury yesterday and am taking oxycodone for the pain.
If this message does not make since, delete it! I just couldn't figure it out
why.
