Fluid bed filter test video

[bdorman]

I wanted to test a bunch of fluid bed filter mediums so I figured I'd video the results. I used coffee filter, newsprint, 20# printer paper, 30# printer paper, Tyvek (Post Office express mail envelope) and grocery bag. If you don't want to watch the video I'll tell you now that I think the grocery bag did the best, followed by 30# printer paper, then 20# printer paper. IMHO it's because their thickness is more uniform. The coffee filter and Tyvek had a lot of streaks of thick and thin areas and I think that caused un-uniform airflow.

One tip I forgot to mention is to shake the fluid bed a little after you get a good airflow going. I find that helps the powder settle down and move about more evenly.

Please feel free to recommend other filter mediums and I'll try to get them and test. I know there are some professional meshes available but from what I've seen they are very expensive and you have to buy a large quantity.

You can get professional precut rounds of the mesh material from TJ's tackle and just a guess from your video 2" -2 1/2" bed??? Just take a picture with a ruler near the opening and for that size you're talking $2.50-$3.00 hardly that expensive. I've had some of the flexible mesh given to me and tried to get more from McMaster Carr, I couldn't match the mesh size. Course with 9 cups for my small and three for my large I'm set.

Great video and test. Sure it will help more new painters with a fluid bed. Thank you for your efforts we need more items and post like this.

Hi Fatman, Yes, it's 2" pvc pipe. I'll contact TJ's in the morning!
Redman, many thanks - just trying to uphold my end of the bargain after you guys have offered me so much advice. Heck, if I hadn't found this site I wouldn't have known you could spend so much on fishing!
