Sand blaster filter system
Sparky, congrats on the new blast cabinet!!! That's one investment you will never regret, and you'll soon wonder how you survived so long without one.
Take a look at some of the vacuum systems, media reclamation and general accessories here.

TP Tools is a fabulous company with great prices (turns out they're having a big sale through February 29), high quality tools and good customer service. They keep me a happy blastin' chick, that's for sure. I highly recommend their blasting gun upgrade kit.
Have fun and be careful with your new toy!
(And don't forget -- it's "puff, puff, passssssssssss"!!!)
