I have been trying to come up with a way to simply and cheaply filter waste motor oil. I deceided on a stand that would hold a 5-gallon bucket, that would drain through a filter bag, into another 5-gallon bucket. This is what I came up with. I mounted the top bucket on an angle so it would drain from one side, more completely. The filter bag rests in a frame to hold it. I have about $10 in steel, I used (#3) 1x1x48 and 1x1/4 bar stock.
I initally drilled a very small drain hole, with the idea that I would need to limit the flow. The filter bag can handle the flow very well, and does not fill up more than an inch or two, in the bottom of the bag. I think I will increase the hole size after this first batch, although. I did thin the WMO with gasoline to speed the process. I first tried a 25 micron bag. It went so well, that I then went to a 1 micron bag (just experimenting!).
I figure I can do almost 5 gallons each batch, and probably a couple of batches a day. I will let you know how it goes.
Do the filter bags work as good as a canister spin on filter. I like the idea of it being gravity fed, but I would use more than one filter just incase something gets through. put some oil through it so we can see the progress.

Take the bags and put a 25, 10, 1 all stacked together. Really want to speed it up, heat the oil and it will run through like crazy. You can heat it over a propane burner and just warm it up. It will fly through the filters. Or when summer gets here put it out in the sun to naturally get warm then filter it.

Our first filter setup was a 12 volt pump with a 5 micron absolute canister that clogged after 7 gallons. We made a bag filter similar to randini's, taking it down to 1 micron nominal, and then put it through the 5 absolute. Other than that, we have not done a lot with canisters.
Randini, you have a good setup there but I would still find a way to but it through an absolute 5 micron/ water block canister. We use a Luber-finer LFF8030
Happy Filtering and keep us posted,

I created a triangle of steel where the filter bag rests. It seems very secure in this holder. Jimma had a good idea I didnt think of, he put 3 filter bags together (50,25,1 micron) in that order.
Thanks
I run the exact same set up except my filter bag is hung from the rafters on a rope with a small bungee to keep it from spinning. I pour from one bucket into the bag which hangs over another bucket.
My filter bag is 10 microns. I pre filter with a paint filter but I doubt if it does any good. I'm pretty small scale - less than 50 gallons per year.
Nice work on your setup. Might be okay if you don't use much oil & if you have a lot of time.
I started out using gravity feed through bag filters. When oil is warm & filter is new, it works pretty well.
But once the filter gets a little dirty, and/or the oil gets cooler, it's just way too slow.
Now I "force" the oil through bag filters. Takes about 3 hours, mostly unattended, to filter 55 gallons through 2 filter setups.
