The DD engineering bulletin # 134 explains the back pressure deal,but Sean is good with the 90 bend.I think his problem is the Farr air cleaner and it's location on a Eagle.I have replaced a few of those with a 1350 CFM ECO series filter and it made a big difference on a 6v92TA a little harder to change as the FARR on a Eagle is about as easy as it gets

Cliff - Do you have a part number for that filter?

I don't have the part no with me, but here is a page off the Donaldson site.

You'll have to find one with the biggest cfm rating possible, while fitting physically in your space. I wish I had room in my engine compartment for the 1500 cfm Eco filter.

every road in the Arctic was built with gravel that has a very high percentage of glacial silt. think silica. think wiping out rings.
There is a cloud of dust created by the wheels of everything carried by the wind further to everywhere...

Having said that, FARR's rectangle shaped filters were a critical aspect of longevity for critical pumps, compressors, and generators.

an indicator on a air cleaner housing doesn't care what's in it. when it's plugged... it's plugged.
the ECO toss can is the last thing I would replace a FARR with. infact. if you do, I might wish to own it if you were to scrap it...
They are an excellent filter system imo etc.

When I changed my air filter a few years ago (the old one's inside pleats were splitting) I used another Racor ECO-BC 094973002. It's rated for 1450 to 1750 CFM, more than enough for a 6V92. After I changed it I noticed more power, less smoke, and the turbo whistled louder and spooled up slightly quicker. There were no Racors of that size in stock anywhere, so Racor in Modesto CA made mine to order - that's better than buying one that's sat on a shelf for umpteen years getting brittle. I bought mine from Harbor Diesel in Long Beach CA: they had the lowest price at the time.

Remember, if an air filter splits internally you won't be able to see the damage unless you can easily look inside it (I made my air intake plenum easily removable for this reason), and a split filter won't show any restriction on the Filter Minder gauge. You could easily end up dusting your engine without realizing it.

The Farrs are fine for a stationary engine or on the fender of a truck but Eagle mounted those inside the engine compartment and they just don't get enough air the way they are mounted

i agree after thinking on it.

i am just old school enough the believe tha the big fat round double elements found on cats and terex and almost every rock drill compressor was the best thing going.

Eco would be my first choice if i had oil bath...just not Baldwin.

had a Baldwin oil filter with a pin crack under the paint...never again.

definitely agreee with this

I cut open one of my Eco filters. It is very well made. Very sturdy. The pleats are glued to the center and the sides. It doesn't look like it would tear apart very easily. I was concerned about water getting into it during a rain storm. No longer. Looks like water could sit in there and not harm it. Much better than the filters I used to buy for the filter housing I had before, or any automotive air filter I have seen.

were you not privvy to the Technomadia ECO filter posts last year ?

An easy way to see if your air filter is big enough is to plumb in a resettable filter minder air restriction gauge. I put one on my 05 just to monitor the air filter and found out that with a new filter the gauge went into the yellow range. I added another air filter and now it stays in the green range except when the filter gets clogged.

ECO is a Parker filter the other manufactures like Donaldson,Wix,Baldwin,Farr and others are licensed to manufacture the ECO series.I have used the ECO for 25 years made by Donaldson and Wix I never had a problem with a ECO series filter IMO and like JC I think it's the best filter on the market for a turbo engine

No I didn't see anything by Thechnomania about Eco filter. What was it about?

jHe had an eco filter, I think made by Baldwin, come apart, ingested, and ruined an engine. Can't recall why, I remember discussion that it might have been a uni-directional filter installed with the airflow the wrong way, or it might have gotten wet. It was an instant disaster. I have a giant ECO Donaldson, with 5" in and out, attached directly to the input of the turbo.

Replacing the FARR Air filter today, I looked at it this AM and noticed there is the intake that feeds into a curved part of the box before it hits the filter and in that part of the box it looks like its supposed to be a 2nd filter maybe?

But it was about 15 layers of metal screen (Slightly rusted screen) that just sat inside that part of the air filter. Thats gotta be a big chunk of restriction. If I held all that screen up to my mouth I think I'd suffocate. I took 14 of them out and left one. I'm sure its supposed to be a washable filter to block larger particles from hitting the main filter.

Is anyone familiar with this? I'll take pics later when I have the new filter and get back to the bus.

thanks.

sounds like a user engineered upgrade attempt to me...never seen anything other than the filter in the intake stream...

Seangie · May 26, 2016, 05:29:03 PM

Here are the pictures of that additional screen -

And here is the air intake. All these screens were in this air intake before the air gets to the filter.

Ive since taken them out, left one for good measure and have replaced the air filter. Hoping this helps with my sooty smoke. Ill let you know if theres an improvement.
