[Shop-talk] single vs. dual stage compressors

[Mark Andy]

Howdy,

So in the latest TP tools catalog (who, btw, are local to me...) they show 
the following compressors that interest me in one way or the other.

>From most expensive to least:

Champion Centurion $1299
5hp, 2 stage, 175psi max, 19.1cfm @ 125 psi, 805 pump rpm

Quincy $1099
5hp, 2 stage, 175 psi max, 15.2cfm @ 175 psi, 1310 pump rpm

Eagle $749
5hp, single stage, 95-125 working pressure, 150 psi max, 18.5 cfm @ 100 
psi

Eagle $649
5hp, single stage, 95-125 working pressure, 135 psi max, 16.5 cfm @ 100 
psi

Campbell Hausfeld $599
5 hp, 2 stage, 12.6 cfm @ 90psi, 175 psi max

Campbell Hausfeld $299
5 hp, 1 stage, 10.2 cfm @ 90 psi, 135 psi max

Sounds like sand blasting will be the most air I'm going to use... I'll do 
most of my blasting in a regular blast cabinet (TP Tools says 10-15 cfm 
required?), but occasionally will use a portable "pot" pressurized blaster 
as well.

Thanks folks!

Mark
