Problem pre-filtering though the 10 microns

[Adam]

SBut if those filters aren't as good as the TrueFilter (stainless) then I can always do one last pass using the 10u TrueFilter, it shoudn't get plugged at that point and if it does it means the paper filter really isn't that great...

That's how I clogged my 10u element, filtering cold WVO that had passed through a goldenrod 10u element. I guess I should give the awsome cleaner a shot, is this the stuff? www.awesome-cleaner.com I wonder how it compares to CLR?

[delicat]

That's what it is as far as I can tell but it's natural while CLR is nasty isn't? Apparently you can pour the soap in water and boil your filter in it, not sure I'd do that with CLR.

I've read some RV forum post and they loved that stuff (Awesome-cleaner). They seem to find it at the dollar stores, wonder if we could get it locally?

I am running ine through 100 u screen, letting it heating with air pumps blowing bubbles through airstones, then filtering it through a princess auto 25 u. I then let it settle and pump it cold through a goldenrod 10u. They seem to last for at least 2 55 gal drums, but definitely low by the end of those. I was using a 15 u with water block before the pump and then the 10u but the $15 15u got plugged almost instantly. I had that filter on the suction side of my pump to prevent emulsion, and I'm pretty sure that having the pump push through the filter makes things runs smoother. It seems to keep stalling out on bubbles when the pump was pulling from the filter. I am hoping to find better filtering solutions, so lets keep brainstorming.

On my van I am using a racor 900 with heating element. It is a tall filter(17"), and they have taller ones. The replacements were less than $6 when you buy a dozen, and they have 10, 5, and 2 u, although that might be just too fine. The other option is the centrifuge. Has anyone tried them out?? They sound great... I am curious, but wouldn't dish out the money till I hear someone has had good experience with them.

Hey, sorry for the late reply. Been working on the Deli fuel tank brackets!

good to hear that you picked up the princess special, the filters work very well and they last a long time. for the cost you can't really complain as it is a low cost substitute for other set-ups while still maintaining great quality. Donaldson are great products, when they are used on $250,000 machines you know they are trusted...

Ok, still no luck with the 10u TrueFilter.

I cleaned it with carb cleaner, (1st time, 2nd time with brake cleaner...) and tried to filter a batch of oil that I had already filtered through a 10u paper filter which is a "nominal" filter I guess.

Results, the 10u TrueFilter plugged in less than a minute. I'm lucky if I got 5 litres out of it! And I had brought my oil to about 140F... So my last option would be to try what the rep for Redline said, boil it for 20 min in a solution of "awesome-cleaner" but that's getting to be a pain. And I've never seen "awesome-cleaner" on this side of the border. Anything else could work?

That monster 10u filter I got from Princess has been working great but it makes me wonder, if 10u TrueFilter is absolute and plugs quickly from a batch of oil from the "nominal" paper filter... are those Princess Auto paper filter good enough?

Spoke with Adam which has a similar set up and using the "nominal" filtration style and still got 15000km of life on his 5u PlantDrive filter so these paper filters might be good enough?

Anyone?

I'm having the same issues as David with my 10u TruFilter element. The 30u works well and I'm able to clean it, but the 10u seems to get clogged almost instantly, and I haven't been able to clean it effectively. The weird thing is that the 10u clogged filter doesn't even look dirty.

So what I'm doing right now is:

• pouring through 100u screen into my 55 Gal drum with a water heating element at the bottom
• heating to 180F to evaporate the water and help settle
• filtering at 140F through a 70u filter on the end of my hose and pushing through the 30u TruFilter and a 10u Goldenrod filter into a 1000L tote
• as needed I fill cleaned cubes from the 1000L tote through a 10u goldenrod filter and let them settle
• pour the cubes into my tank

Unless I can figure out a good solution for the 10u Trufilter in the next couple of weeks I think I'll return it and keep using the 30u filter. And if I had do it all over again I think I'd go with a centrifuge. The trick is finding a cheap/free high pressure pump, which SteepCreeker managed to do as I described in this post here: http://www.delica.ca/forum/building-my- ... -2879.html

Hey filterers,
I can't say anything about your redline filters, but I've been using a large water filter with a 50 to 5 micron filter and I've cleaned about 200gals without heating the oil. The filter housing and one filter was about $100. I can't remember the name, but Sean from Courtenay once posted a picture of it.

I should also note that I stop pouring oil into my preliminary drum once I start to see cloudy fats and gunk, which I believe helps prolong the filter.

Good luck,

David

Ok, FINAL WORD!

Spoke directly with TruFilter rep and was advised that the 10u filter is wrong for our application. They are designed as a fuel filter (gasoline) and just can't be used for our needs. The 30u is their next size up and they recommend it (no surprised here as I'm really satisfied with that little one).

Just for the heck I've asked him if they have an application for on-board oil filter for the Delica and he'll call me back once he finds it. (That would make a hell of a oil filter! Sure the price will be scary but since we're planing to keep this thing for a few generations it could pay for itself at some point. Not to mention less waste...)

So this is it, No Can't Do 10u TruFilter.

David

Quick edit:
Called back RedLine Pumps who agreed to take the filter back. He was pretty upset though, not at me but at TruFilter as when he purchased them he was told they were for WVO... It's their battle now!
Also, he apparently sold around 500 of those filters and only got 6 back so not sure why some people have problem while others don't. But since the inside screen is the same as those used for medical purposes (filtering blood...) which is probably made by Purolator then I wouldn't really expect discrepancy between them. That's the way I see it anyway!

I should never had started my last post with "OK, FINAL WORD" 'cause it wasn't...

Now I'm in direct contact with the owner of TruFilter (Ken Browne) and he doesn't back up what the Canadian dealer told me. Browne actually fully endorse David Miller at RedLine pump. They will get back to me once they figure it out. In the mean time I'll hold on shipping my filter back but I'm still without answer as to how to clean or why it doesn't work (aside from too minimal surface area).

Hey David,

Thanks for all the effort trying to get this sorted out. I've been too busy with the house project and the family to properly follow up on this, glad to have you on our side

Well, my inquiries didn't fall into deaf ears...

The owner of TruFilter (Ken Browne) assured me these were design for WVO application and also said that David Miller at RedLine Pumps was very knowledgeable with WVO filtering. At the end, sounds like RedLine will be sending a written outline for the method and a range of cleaning products that will work with this process.

So I'm holding off on sending mine back. For now...

David,

Any update on your redline system?

I've run min to filter my biodiesel with no problems but was wondering how your veg.oil setup is going.

[delicat]

Well,

I boiled the hell out of it along with some cleaning product (CLR?) and it helped a lot but still not to my dearest expectation. I can filter down about 10-15 gallons before I need to boil it again. I was supposed to call back Ken at Trufilter but neglected to do so... with your post it reminded me to call him and I've left a message, thanks to you!

I guess I just don't like to give up so easily so I'll try again with different approach to see if I can get better results.

Thanks,
David

I'm same boat. The 10u filter doesn't seem to run for more than 1/4 of a barrel before clogging. The 30u works well, it will last for several barrels in combination with the 100u screen and the 70u pickup. So I'm still using paper GoldenRod elements, which seem to clog after about 1/2 a barrel. The weird thing is that I can reuse the paper elements several time after I remove them set them aside for a bit. Then they seem to filter almost as well as when I first used them. Still trying to figure this one out.
