water must be drained from compressor tanks daily, in most cases, in humid areas several times a day is preferable, so having a drain valve extended from under the storage tank to an easily accessed location sure helps.
the water drains frequently get clogged with crud inside the storage tanks on older compressors and at times you'll need to use some method of pushing an opening thru that crud in the drain, to allow water to drain.
you can add a desiccant air drier to the pressure lines and routing the air line supply lines along walls , at a slight upward angle or slope as distance increases from the compressor in the shop,so any water that condenses, drains to a second easily accessed location with a ball valve ,or second drain
there's cartridges with desiccant, that will work short term, but they tend to get saturated in short order if the tank on the compressors not drained almost hourly

one or more of these moisture trap/drains along the wall helps, mounted along the wall, between the compressor and the tool hose connectors .
oiling tools frequently helps

yes there are lots of air driers available, but for most of us that don,t paint cars the cost is a bit prohibitive.
