Heres how I hooked up my Shop Vac to my Blast cabinet ,
I removed the filter paper and wrapped the cage with Scotch Brite we get it in bulk "cheaper that way" at work , so I purchased a 2ft chunk .
I then cut a hole in the wall of the shop and installed a dryer vent to the outside world made an adapter to reduce down to fit a shop vac hose , purchased a replacemnt shop vac hose and have it hooked to the vent side of the shop vac , all the fine dust vents outside and the scothbrite knocks down the bigger stuff in the tank but takes a very long time to get plugged up.
Now I know it is hard on the inards of the shop vac but for all the more I blast,it is holding up well ..besides it was my old one i retired after it rolled off the deck one day and broke onna the wheel mounts off.
Just a tip
Tim
