Can anyone identify this 40 year old filter?

Looks like we need to do some repairs on our sand filter because we are shooting a lot of sand into the pool at high rpms. But no one knows what type of filter this is? Other than old and big
Any ideas?
Thanks

Jan,

I'm pretty sure that is a "still" and not a filter..

I'm betting that @JamesW knows...

Thanks,

Jim R.

It looks like it was manufactured by NASA in the 70's.

You sure it is a sand filter and not DE? This looks similar...

I'm not sure what the model number is.

I would replace it with a large (400+ sqft) cartridge filter.

That appears to be an antique American Pool Products stainless sand filter. Saw one about 30 years ago. American Pool Products, bought by Pac-Fab, bought by Pentair.
