OK, I understand the cooling, but still wonder if this is overkill. Why

sensed there was a problem. Is cooling of the air that big a deal?

Some geographical locations have air that contains much more moisture
than others. Also, some guys have applications that are much more
moisture-sensitive than others. If you want to spray paint, for example,
you need *dry* air.

If you blow air do you see a mist of water? If you direct the stream against
a piece of metal plate, do you see water "piling up"? If so, then you
have a lot of water in your air.

Here in the Central Valley of California, during the summer months, I
drain my compressor maybe once a month, sometimes even less. I go to
Newport Beach or similar places to service machines, and the guys are
using the air hoses like squirt guns, spraying long streams of water.

Climate makes a HUGE difference.
