Craig:
Tank size and motor size aren't as important as delivery
rate. That's the important number. Units with higher
delivery rates will have have larger motors and tanks.
Up until five years ago, our main compressor at home was a
belt driven Craftsman unit purchased about 1971 for $200.
It's specifications are:
Sears model number 106.154580
100 psi
1 HP 17.8 amp at 115 V or 8.9 amp at 230 V
12 gallon 8.1 SCFM dispacement
Delivery rate 6.4 SCFM @ 40 and 5.4 SCFM @ 90
It is too small for:
5 inch orbital sander
Generic 4 x 6 jitterbug sander (I kept trying to find a
sander that would work with the compressor)
TriCon siphon feed sand blaster with 5/64 air jet
Craftsman 3 inch rotary cut tool
Generic Straight line air sander
Ingersol Rand nibler (Same reason as the sanders)
I now have a Sanborn M165B500-20 belt driven air compressor
purchased in 1994 for $369. (I believe you can get one for
about $400 on sale)
120 PSI
5 hp 15 amp at 230 volts
20 gallons, it now is sitting on a 47 gallon tank
Delivery 12.7 SCFM @ 40 PSI and 10.6SCFM @ 90 psi
It is big enough to run the above tools. If you can spring
for the extra bucks you will never be sorry. The Craftsman
has been very reliable and a good unit, but it was just too
small to operate any tool continuously.
