Heres one I finally got around to putting together.
I always used the screen in the coolant tray but its not good enough, in one month I clean 20 gals 4 5 gallon buckets of alum fines out of the tank, every month too.
I use evap cooler pads in the tray, 7 bucks and you can cut them to get 2. they wash out good too.
so I installed the filters this AM . fittings were 197 bucks form home depot.
I dont know how long it will take for the filters to dirty up,( so I installed 2 of them with check valves) the tank was clean when I installed it and fresh coolant
I have NO freaking clue if this will work or even help, or even be worth it, so if anyone has any feed back let me know, the only thing I am worried about is the filters clogging up, I was going to run for a few days then check them out.
filters canisters were from lowes
they are whirlpool "WHKF-DWH"
the filters themselves are the coarser ones.
if I remember correctly the canisters and filters cost 30-40 bucks each
