K&P Engineering High Performance Stainless Steel Micronic Oil Filter

[135boost]

I have a few micron dust collection system in my guitar building shop. It has a 36"x30" or so pleated cannister filters. Periodically I have to clean it out. I can see the dust because a lot of my wood colors are dark exotic hardwoods. Let me tell you, with a hose I spend 30 minutes getting to where the water comes out clean. I'm unconvinced that the K&P filter gets cleaned they way they do it.

If I had this filter, I'd consider buying a gallon of acetone, putting it in a sealed container (like a paint can), and dunking the the filter in there, where I could vigorously shake it. A better solution would be something that screws to the filter and lets you push fluid from inside out (like a large syringe/plunger).

The issue with the spray approach the video shows, you will get no spray force on the filter to dislodge metal particles, and you can't reach the top 20-30% of the filter from the inside. With my dust system I can get right on the inside of the pleats with a high-pressure water hose. That's what it takes ...

I like the magnet, though.

I fully agree with filippos statment that cleaning on that way does not do the job.
My profession is with hydraulics and there these kind of metallic mesh (not as fine as this) has
always been outperformed with paper or glassfiber reinforced paper units so my vote is going for stock, 50-90% of metallic partickels on these kind of engine is not magnetic before engine
seize, nornal bearing lead copper or aluminium so the magnet is doing only part of the job,
nice feature othervice and better than none.

I change my oil every 3000 miles. I dont see how HP would effect oil pressure either but i've seen stranger things. Could be my dual oil cooler set up as well. I don't know whats causing my paper filters to crush in, I just know they are for whatever reason. I've seen it happen to others as well.

Are you running series or parallel for your oil coolers?

This reminds me of an important point. Anyone operating an auxiliary oil cooler will want to minimize filter back pressure to maximize oil flow, especially when operating oil coolers in series where the flow resistance will be greatest. So a stainless steel filter like the one discussed in this thread may be a really good idea to improve oil cooling, especially for those who use an auxiliary oil cooler and track their cars.

I like the idea of the of the pressure loss being so small with this filter, but I can't help but think how much I will hate cleaning it. And that is assuming I haven't let my cans of spray solvent get used up and realize only too late that I don't have enough.

I have a feeling that a cheap HF parts washer will get the job done too.

 

[Jeffman]

Both good points. Maybe this stainless filter is really best for those who track their cars where high oil temps matter the most. It may be too much of a PITA for those of us who use our cars mainly as daily drivers.

In series.

I thought the same thing but I think any parts washer is likely to make the filter worse as it...... Filters the solvent while attempting to "clean" the filter.

It won't matter if you have the solvent spray, because it won't clean those filters anyway, I suspect...

Couple things. Don't worry so much about cleaning the filter to the point where it has no particles left on it. The dirtier the filter the better it filters (of course until it get's completely clogged and nothing can get through). Just try not to introduce particles from outside walls to inside walls when you clean it. This filter is obviously not going to filter out small particles as good as synthetic or paper filters but it will flow better reducing pressure in OFH. I have almost 3k miles on my SS filter and so far so good. I hope my oil filter housing gasket will last longer now when I have lower pressures and temperatures in my OFH. I noticed lower oil temperatures but can't tell how much credit goes for the filter because I did some other modes to reduce oil temp.
BTW I do engineering for company that manufactures pharmaceutical filters and filter housings

 

[Jeffman]

Nice. Expert advice.
And that side benefit that reducing pressure in the OFH will also help minimize OFH gasket leaks is tremendous. Thanks for your comments!

I am always disappointed in the cap oring leaking prior to the next oil change!

 

[fmorelli]

I was thinking the OFH gasket I don't want to see leaking is the housing to block gasket. PITA to do on every BMW I've owned. As for the oil filter top cap: http://www.ctsturbo.com/cart/produc...MW_2_0L_3_0L_Oil_Filter_Housing-4982-679.html

Agreed.
That “B-Cool” vaned oil cap also looks like a winner - both neat design plus it could also help cool the oil a little. Do we know that it’ll work with the stainless filter?

 

[fmorelli]

No idea - but if it works with a regular filter, don't see why it wouldn't?

i have never had a issue with the cap oring.Tip,always lube the cap oring,change oring every oil change,clean the the old residue,turn slowly.i have been married to mine since day 1(2008).But that BCool oil cap does look cool,like the vents

 

[fmorelli]

I'd be curious to know what the actual oil pressure drop is across the filter and what exactly that has an impact on, if anything. I would imagine BMW/filter OE worked this out. Is there a problem to actually solve here?

Filippo

 

[Jeffman]

OE certainly works fine for OE performance. But most of us here on the forum, I think, like to push the envelope... we’ll beyond OE performance.

 

[fmorelli]

I hear ya. I was thinking about that and then thought, how does that effect the oil filtration system? We don't change oil pumps or really do anything beyond oil coolers.

These style of filters are way easier to clean than you may think. Debris doesn't get "lodged" or "stuck" in the filter as much as the paper type filters due to the type of medium. Best way to explain it is that it basically just rests on the filtering medium. We use these on a lot of diesel engine applications and honestly it takes less than 5 minutes to clean one filter like this thats double the size. Medical grade SS, is virtually non stick.

Although, i have never used soap and water on these types of filters. Normally, brake cleaner with a pinpointing straw to clean, then dunk and agitate in a a cup or bucket (depending on the filter size) of alcohol, then let dry.

I've personally always hated cartridge filters because of the failure rate of the paper filters like that being way higher than the canister filters. I also have bounced around the ideas of a Canister conversion. But with this, no real need.
