I have a Craftsman 60 Gallon 2.9/7hp 175 PSI compressor and a 40# Harbor Freight blaster. Still need to wait on compressor occassionally. Sandblasters are real air hogs.

The blaster works great IF you sift & strain the media (Pay close attention to how big that IF is!). I use a piece of screen door material as the screen and place it over the fill funnel. I also re-use the Nickel Slag Material 3 or 4 times.

Any small foreign objects or media chunks larger than the ball valve openings or nozzle tip opening will clog the blaster.
When that happens (and it will happen) you have to either:

1.0 turn off blaster, remove tip, look for obstruction, reinstall tip. If that doesn't work.
2.0 turn off blaster, purge air from blaster,open valves and lid, blow air backwards via nozzle, if that doesn't work,
3.0 turn off blaster, remove all your personal protective equipment, dump all the media back out and refill.
