Yes that's what I'm figuring to find, probably something intended for mining or food processing. I went ahead and got a 48"x96" sheet of 60 micron stainless, which should buy enough time that I can more fully research filter cloth. Thanks for the lead, and letting me know that's what filter type is used in the Profidrum, as I was about to ask.

What I meant was "I was going to ask whether the Profidrum used stainless or fabric."

The plastic chain came off the drum, causing the drum to stop, the incoming water to back up and causing a small flood. The chain had stretched a little (they all do, even steel ones) but what's annoying is that the way it's made, two links have to be removed instead of one. Right now it's too long, and too short if shortened by one segment. I reversed the drum's rotation direction which changed the angle of force on the drum and bought me some time. This weekend I'll relocate the drive motor to take up the slack and will design in a tensioner into the v2.0 model.
Oh, a couple other things I've learned:
1. Garolite absorbs water to some extent and expands. Depending where it is it can cause parts to jam up.
2. Using a white IBC is a bad idea unless it's well covered. Algae is actively growing on the sun-lit side and is starting to get invasive. Version 2.0 uses dense HDPE panels so it won't have this issue.

3-month update:
Yesterday I noticed that not only was the RDF cycling more often but when it did, the water levels weren't changing as much as they used to. The last time this happened it was due to the filter cloth tearing, so it was odd that it was happening so soon after the filter cloth was replaced.
Turns out that the screen-covered exit in the moving-bed filter (in a separate IBC) which the RDF feeds had small K1-type media which packed around it, in addition to some bits of algae (probably left over from the first time the filter cloth tore). Hosed it off and the water level in both tanks immediately dropped a good inch and the RDF started operating normally again. Just another think to keep an eye on!
