I have a similar problem with an Eastwoods table top cabinet. I'm using
coal slag from Tractor Supply. I find that the slope of the cabinet
bottom is not steep enough to recycle the slag well. When I see that
there is less media than I expect, I put my finger over the nozzle &
blip the trigger, causing any media in the hose & around the pickup to
blow backwards, then settle down. I am then able to blast for a few more
minutes, until it happens again. I also use a 60 gallon single stage
compressor. Here in central Texas it is quite humid most of the time so
I use a small in line water separator at the inlet to the cabinet. I
should buy a larger one but haven't gotten around to it. If I am doing a
lot of blasting I need to empty it about every 15 minutes, even though I
empty the water out of the tank & drip legs at each startup.
Peace,
Pat
