Doug: The Home Depot model you speak of has the two cylinders cast in
one block. The Puma has V twin cylinders. Runs much cooler.

Hi--Home Depot sells the 6 hp (15 amp) 60 gal, two cylinder single
stage
Cambell Hausfeld compressors here in Los Angeles for $379 (just saw
the
ad last night). I bought one several years ago and have used it a
good
deal (sand blasting, painting, air tools, etc.) and it has been great.
These cast iron, oil bath single stage compressors generally put out
about 9-10 cfm @90psi which is good enough for most applications
other
than large nozzle sand blasting.
Although I don't really NEED more flow, what I wish I had bought,
though, is their "quad model." It has a 7 hp (21 amp) motor, and a
very
nice 4 cylinder, single stage, all ball bearing, cast iron pump.
Though
it puts out substantially more air (17 cfm @ 90 psi), what I really
like
about it is that the pump spins at a "leisurely" 840 rpm compared to
the
1050 rpm that most pumps turn. It sounds much less annoying, almost
relaxed, compared to the 1050 rpm twin cylinder pumps.
I know this may sound trivial, but if you spend much time out in your
shop listening to the thing run, they can get on one's nerves after
awhile. It also cannot be good for your hearing.
While I'm complaining, IMHO, the "oiless" compressors really put out
a
racket--I would not buy one for serious usage simply based on the
noise
they emit.
