I finally moved up to 1/2 hose for the supply and all my clogging problems went away. I also run 3/4 inch steel pipe from the compressor to the filter and water traps, then 1/2 rubber hose to the blaster. Last time I used it I went 5 hours in 65% humidity without a single clog. My point is I think Ken is correct, the volume of air is too low. I also pulled the plastic feeder at the bottom of the pressure tank and drilled additional holes to allow more media to drop down. With that large of a compressor the only possibility is the air volume is too low. A quick check would be to remove a couple of the water traps and see if the situation improves.
