Also good to run an extended line--25 ft or more--from the compressor to the
water trap. That way the air cools and water condenses before it hits the trap.

One thing a big tank can give you is cooler drier air. Air straight out of the
compressor is hot and wet. As it cools, the water condenses. A tank big enough
to ensure the air being drawn off is room temp means the driers have to work
less hard. I've worked with some industrial set ups that had oodles of
compressor capacity to meet their peak load, but used large tanks to buffer the
temperature and moisture.
