That's after compression and mostly to dry the air to the best of my
knowledge, its a big problem if moisture is not removed, at the other
end of the pipeline, try using air power tools with oil and water coming
out or painting with moister in the compressed air,

I'm not a very heavy user of my air compressor. Regardless of the pro's

and

con's, it probably won't make a lot of difference in the long run for

me.

I

had noticed that many of the commercial duty compressors had cast iron
compressors, if that means anything. Maybe aluminum with cast iron

cylinder

inserts is the best way to go. Anyway, my compressor is working fine

for

the time being. I'll just have to wait and see about the longevity

angle.

Aluminum cools faster than cast, which is why many compressors and
air-cooled engines of all flavors with iron inserts have aluminum

cooling

fins.

Though it may have been a buy recommendation for you, it does have its
drawbacks.

It's not longevity. I didn't say that. It's efficiency. The reason you
want fast cooling is it gets you more compressed air faster. Warm air is
less dense, remember? Suck into a warmer cylinder and you start out with
less.
