Onboard Centrifugal Oil Filter

[MMcCallie]

Does anyone here have experience or recommendations on using a centrifugal filter as an onboard vehicle fuel filter? Was talking to my buddy about doing a couple conversions and he told me about the centrifugal oil filter on his semi. He said i should look into them.



B100 has left me stranded when i was unprepared, i now carry extra fuel filters. I'm looking into ways of heating as i've been unable to start due to frozen fuel, but i'm mostly concerned with reducing filter replacement in this post. I'd like to quit paying for B100 and run WVO in the future so i want the system to be entirey onboard.



I've done a little reading about dieselcraft and Cummins centrifugal filters. I've read that they are capable of removing particles down to the size of less than 1/2 micron. The Cummins filter appears to offer more effective filtration but still requires replacement of the filter. I've also noticed that lovecraft has a heated filter that never needs element replacing.



The idea of merely draining and cleaning the element appeals to me since it doesn't require carrying extra parts. From what i've read, centrifugal filters seem to be very effective at removing filth from oil. Haven't yet read much about how they work out with WVO onboard a vehicle, heating will obviously still be necessary. I've had filters last less than a week so i'm anxious to improve my filtration, tackle heating, then build a WVO tank and start saving some money.

hello MMcCallie



here is another brand

Davco Technology



never have tried one good luck

It seems your looking for trouble , if your having problems with bio , you will have more with WVO .
I have been looking into this also , started looking at Spinner II , for oil filtering , it may not work for fuel , not enough volume , if someone is making one for diesel / bio , then I'll look into those .

I bought a diesel blazer from a guy here in oregon who had a similar setup to the Davco and was running svo with very limited pre-filtering. I paid $400 for the blazer 'cause it needed a new IP,as well as new interior (he spilled wvo all over inside and it STUNK!)

Hi guys,
Thanks for the responses. I've had the Davco bookmarked for several months but i don't see anything about it being a centrifugal filter. Am i missing something? The Davco appears to have filter medias that will clog and must be replaced which is what i'm trying to avoid.

I'm interested in centrifugal fuel filters that big trucks have like my buddy's KW with a Cummins N14. Some, like the Cummins model need to replaced but only about once a year. I'm mostly interested in one that doesn't have to have filters replaced as filters are extra waste, even though the Cummins filters are entirely incenerable. Do all of the dieselcraft filters have to be driven by their own motor? Looks like the Cummins spins by oil flow.

If any of you have done research beyond what i've Googled in a few days, please direct me in the best direction. I'm especially eager to hear from anyone who's been using them for making biodiesel, but especially on a vehicle. Since my Cummins lift pump only flows about 10-30 psi, i'm curious as to whether or not the centrifugal filter would spin fast enough to have much effect. From what i've read, they seem to like to spin the oil at around 7,000 RPMs.
Thanks,
Matt

Weather its me or others , it does seem like , we all sometimes miss read , do not get what the original posts point was ?
So back to that , I started thinking about this when I looked into the Spinner II [ oil ] , flow refers to volume not pressure , this is where it may be that the problem is in using the spinner II , this is just thinking & talking about it , no facts yet , so I am also still looking .

JFaughn,
I know what you're talking about. Regardless of psi, does the lift pump flow too little or too much volume to make the filter spin? Engine oil pressure is usually 25-75 psi so i figure flowing at that high pressure would be enough regardless of volume.

Not sure how it will work for fuel. Maybe that is why some have a motor. I may have come across another centrifuge company, amicon. Hoperfully someone has tried an onboard centrifugal filter and can provide experienced advice.

fuel filter/centrifuge combo

Here is a Co called Dieselcraft they make one but it makes a mess taking it apart.

cj , that seems to be what we are looking for , thanks .

Yes CJ,

Dieselcraft was the first one i mentioned in my original post. They have an onboard two stage system but it doesn't say anything about SVO or WVO. Anyone have experience with it or know what to expect running one on a truck with WVO?

Their alternative fuel centrifuge filters appear to be stationary, requiring a 1/3 hp motor. I'm looking for something that will be effective without requiring its own motor.
