Yes, and if they had a dryer, they would not have these problems.

Correct! Then they'd have the problems associated with maintaining the
dryer! (yes, they would! G)

Coalescing filters don't remove enough air, but are cheap to buy and
cheap to operate. Refrigerated filters are damned expensive to buy, but
fairly inexpensive to operate. Calcium chloride absolute filters are
medium cost to buy, but need continual replacements.

I have an old refrigerated dryer in my shop. It is old and ugly, but
works great, no problems with it. I routed blasts of air to the
outside.

An automated drain on the tank, and another on a coalescing filter SIZED
TO YOUR USAGE volumes, is the best combination.

I found a low headroom float drain at mcmaster carr, I will put it on
when I get time.
