Our first house came with, um, no documentation for anything regarding the pool. Not that I expected any.
The filter I recognized from when I was a kid, so I know it could easily be over 35 years old. Unfortunately I don't know much else about it except that it was made by Purex. The canister is 24" tall and has a diameter of 20". The entire unit is 36" tall.
Recently it's started leaking DE into the pool. I took it apart and checked the grids and the manifold and everything else that wasn't too much of a pain to get at but couldn't find anything obvious. Since I don't know the model I'm not even confident that I could get replacement parts for it anyway.
If someone could identify this I would appreciate it.
The next step is to find a suitable replacement.
