Dang it this thread just died eh. Everyone still enjoying their molecular sieves?
Krunch are you using the fiber glass wool inside your SS tubes instead of the beads or as an filter for the dust?
Gray are you just using the replacement filters inside your own SS like the ones here?

Very nice very nice. How often do u change it out?
We switched to less dusty and messy refrigeration dual molded #48 zeolite filter drier inserts, inside a stainless case that we make out of sanitary tubes, and install on the input to the pump.
The case has a tangent intake, to minimize direct impingement on the filter inserts. We've already gotten feedback regarding pumps saved, despite an operator ooops.
It is also easier to service on the inlet side, because you don't have to recover it first.
Havent changed it out after 20lb extracted. Think I will change it out this next run...
No issues with the insulation breaking down? I just think of the stuff in dry wall and how it breaks down a bit. Maybe a little different though?..
Definetely liking the dual insert mold idea though seems simple and clean.
Nice I'll probably try this first but wouldn't mind trying the sieve. Anyone know a good place to get the inserts?

That was the conclusion I came to in this thread like a year and a half ago. Those 48 cubic inch cores are bonded with kaolin and phosphate and are way less dusty and can be recharged in a vac oven. Took some experimenting and weighing of the cores but eventually I figured out how many runs I could do before recharging them. You can also stack those cores and make larger ones.
I remember when I was calling around and talking to engineers of the manufacturers, one of them said they only get a certain percentage on one pass. And the more they soak up, the less they keep soaking up. I never did it but I thought having 2 of them inline would be sweet.
I remember crunching the numbers and the 100% molecular sieve cores held more water. I believe the zeolite is used to trap other contaminants in AC systems. There are several formulas for trapping several things buy since we were only concerned with water I had thought (could be wrong) the 100% molecular sieve ones retained more.
I scored a box of new ones from the manufacturer danfross on ebay. They were super cheap, like 12 bucks each or something. If you keep an eye out you can get a good deal. I would still blast em with the air hose everytime before inserting them into the housing, just to be sure to get off anything that might have rattled loose.
Do you know anywhere we could buy some of these SS setups you're describing setup and ready to go? If not, could you possibly provide more detailed plans/instructions on assembling them ourselves?
