.... Will you be offering special pricing for forum members? ....-

There is no member here named Mr Dieselcraft. These guys are buying these filters on their own and are not in the biz of selling stuff.

If you read the complete thread you will find one supplier has offered a discount for bulk purchase. Nothing to jump at but still cheaper.

Mr. Dieselcraft just joined yesterday, to ask if he could use my pics and comments. Probably because I told him about this thread and he has been getting many calls and emails from people here. Yes you can use them.

1. lube oil filtration normally

2. After cleaning the centrifuge and switching quick coupling hoses, WVO filtering? then back to 1. after cleaning.

2 birds with one stone -

Good idea. Do you know any quick connects that will not leak at all? I would hate to have oil slowly dripping from my engine. The hydraulic oil quick connects I have used on my backhoe always drip even though they have o-rings.

maybe pipe unions???

edit: hyd. fittings may? work fine under these low pressures.

List price with bracket is $289 we currently have offered a discounted price as an introductory offer of $230 and no frieght charge ...there you have the club discount :-)

Unit components come from non-usa sources. Parts are inspeced, assembled and painted here.

Warrenty is 24 months no questions asked exchange. Engineering expect them to run for a minumum of 10,000 hours.

No problem in switching oils it will not know the difference.

Many thanks.

How does this centrifuge stack up against other, bigger ones. I'm looking at trying to filter a lot of oil down the road. What would this thing due per hour, how often does it have to be cleaned?

We have three models

OC20 holds 6.4 ounces of contamination and can flow 50 gallons per hour @ $230 with mounting plate. $198 without mount.

OC50 holds14.4 ounces of contamination and can flow 108 gallons per hour @ $383 with mounting plate. $343 without mount.

OC200 holds 48 ounces of contamination and can flow 300 gallons per hour @ $1560 no mounting plate supplied but can be quoted.

You will have to base cleaning intervals on quality of the oil and experimentation.

Lead time is now running 14 days

Hope this helps.

Thanks
John

I am glad that there is enthusiasm for this...but has a thorough testing been done to establish that this is capable of completely removeing suspended water?

I just read the past 8 pages..and I see some preliminary teting for water removeal has been competed...but it seems to me that most are assuming that the unit has been proven to remove suspended water. If I missed the testing procedure please point me to it.

So far there are only 2 of us testing this here. I have run 4 different batches ranging from 15-40 gallons, all mistwashed and I left visible water in the oil. And it was removed in all batches after 4 passes according to the hot pan test. As more people get these and try it with different oils, temperature, and climates is how we will get more "thorough testing".

As I said way back in the thread, the higher your humidity, probably the higher the temperature you will need to run. And if you get it hot enough you should be able to flash off water in any climate, the temperature and number of passes needed in different climates is what further testing should determine. Lots of variables, so anyone else testing please report your ambient temp. and humidity, temp. of oil, and number of passes until all water removed.

I am sure if you ran it hot enough it would flash evap. in 1 pass like Tims FE, but I think you need multiple passes to get sub-micron filtering anyway.

Visible water is much easier to remove than suspended water. I am not too surprised that it is removed...but if I understand correctly no one has tested to determine if suspended water is removed. Yet..I see folks assuming it will. Even you have recently made statements that it completely removes water from wvo. I am sure it is not your intent to mislead anyone. But people will assume that you have thoroughly tested to back these type of statements if you make such bold statamants.

Maybe it would be best if we discussed how a through test to determine if all water IS removed might be undertaken before everyone assumes it does and begins depending on them to do so.

OK does that mean you know that the pan test doesn't work to show suspended water? If so then I think lots of people may have suspended water problems they don't know about.

Any visible water I had quickly became invisible after running the centrifuge, it makes a milky emulsion that would not seperate by settling. Does that meet your definition of suspended water? What tests should we do?

I suggest someone take a sample of the oil that has been run through the centrifuge and send it to a testing lab. Ask for Water & Sediment by Centrifuge ASTM D2709 100 ml Cost is about $35. I believe this will tell exacting the water content of the sample. Suspended or emulsified water, it will not matter

We use this lab: http://www.herguth.com/testing/method.htm

A lab test would be interesting to see what micron level we are getting filtered to, but I think for water content it wouldn't be worth it. Since each person's results will be different based on amount of water to start, ambient temp, humidity, temp of oil and # of passes, we need a simple test we can do on each batch of oil. The pan test is what I thought was best (better than the "crackle test"), but maybe Dana doesn't like that test anymore?

I need to correct my holidng capacity numbers as follows:

OC20 holds 200 ml or 6.8 fl oz
OC50 holds 500 ml or 17 fl oz
OC200 hold 2000 ml or 68 fl oz

That milkiness sounds suspicious. Have you tried more ways besides settling to clarify the oil, like adding salt or settling at high heat, just to see? Or as Tim does, add flour. Not that we would want to do that after we just cleaned it, but for the good of the order. I would sure feel better about ponying up the cash for a unit if I knew that either there was no water or the water in there is in a form that will not damage my IP.

Of course, this whole wvo movement is all just experimental at this point anyway...

That milkiness completely cleared up after running through the rig for about 15 minutes as I reported way back in this thread. I mentioned that again now because I consider that was suspended water that was then removed. I don't use settling any more since this rig works so much faster and much finer micron level.

Look...I asked you to point me to the testing you did. No need to get testy about this. All I am interested in is that it is thoroughly tested before everyone assumes it removes suspended water.

Now..as I said before ...if you want to give me a hint where the info on testing for water is posted I would appreciate it. I was unable to find it when I looked.

Dana is RIGHT. The only way to get a real test and know exactly what is left in the oil, no matter how the oil is processed, is to have a qualified lab test done. You will get a printout of what is there and what isn't there. You can however ask for testing of particular item. I had my oil tested and it was well worth the money and eleminates the guessing.

That's where the rabbit did it in the caggage patch. here in the West
