I had the same problem and I started sifting the media before I put it in the pressure pot. I didn't have anymore problems.

Re: Sandblaster Help

Mine did the same thing..........It especially clogs up when Its hot outside. Its the moisture. Put the water separator as far a way from the compressor as you can. Mine will still clogg a bit so every 2 min. I put my finger over the end of the gun and pull the trigger to back blow the media.

If I do that periodically it never cloggs.

Re: Sandblaster Help

If it's a pebble that clogging it then you need to sift the media or use a lrger tip. I used the same setup for my frame. The Black Beauty works well but does have a few large stones that will clog you up. The blaster will need more air pressure with the larger tip so adjust accordingly.

Re: Sandblaster Help

8bolt,

I think all of the guys are right about the clogging issue. Sifting or screening your sand is definitely a must and you have to watch the moisture in the lines as it WILL clump your sand and clog your lines. I've have been having the same problems with my blaster. Get a Good Compressed Air Filter. I am now using the Motor Guard M-100. I have this setup in my garage for both my Sand Blaster and my Powder Coating Setup. I have not had any problems since.
