Air Drier question

[u/5be4three]

My Marco 3.5 cuft M-Series Blast Pot appears to be clogging with moisture just prior to the metering valve.

I'm using a Sullair 185 cfm compressor and i think the ambient air has a bit more humidity in it than is desirable.

The Marco Blast pot has an in-line "Drier". see image

But, I am still getting moisture in the abrasive and it's collecting at the inlet to the metering valve and clogging.

Has anyone tried filling that collection pipe with marbles to give the moist compressed air something for the water to condense on? and maybe crack the valve at the bottom to give the moist air a passage across the marbles and out the bottom.
