Air fillter

[5B Steve]

 

    I just came upon a sight Walker engineering ,AIRSEP FILTERS kinda looks like a large K&N product. Not knowing the micronage,

    has anyone ever and any experience with one of these?  Also, what is the air consumption of your engine?

Walker has been around for years but I don't believe the air cleaners are approved for highway engines by any manufacture mostly used on marine and generator use,tell us what engine you need the CFM for 

good luck

   Luvrbus,

  I was wondering , because from what I was reading, they could match the in coming air to what air filter you might need. On my

   8-92N  I had the hose off for a few minutes to see what type of flow I was getting. Seems it was alot more not going through

the 4 canisters I have. I had thought about something like a K&N for more flow. I hope all of this makes sense.

  Thanks,  Steve 5B.......

I believe Sean had a K&N (or similiar style) filter leak dirty air around the filter and caused the need for an engine overhaul.  I thought K&N had quit making heavy duty filters, but they show them on their website.  They do say the heavy duty filters do not need oiling.

The consenus of most folks on this site seems to be to just to use paper filters.

Not sure I would use what Walker is selling. What is the matter with what the Manufacture recommended and installed?

From tests that I remember reading (sorry, I do not have a link), the K&N filters can give better airflow for a given surface area, but they also do not filter as well.  I personally would go for dependable filtration.

    John, good question, For some reason it seems that mine isn't getting enough air. There isn't any obstruction and I still get

    some black smoke every now and then. The air filters are new.

An 8V92 was not the original engine in your 5 I'm fairly certain.  Were the filters upgraded when the engine was changed?  It sounds like you may have four filters.  A single modern filter canister from Donaldson would probably be a nice upgrade if you can find the space.

Now the experts can get to the bottom of your problem. Walker may be selling a good product but in the past has took some bus nuts to the cleaners. He served his time and is starting over but needs to prove himself to me be fore I will buy.

Brian, I believe that Sean's issue involved bad tubing connections and not the filter. 

Our buses have a unique need for air filtration.  The engine and filter are behind the wheels and those wheels really kick up a lot of dust and nasty stuff. 

I have never seen actual tests involving K&N filters other than their own that show increased flow.  If you increase the flow with the same area, the obvious logic is that the media is not filtering at the same level.  It would be interesting to see a test in a dusty environment.

Given the drastic results of ingestion of abrasive dust, I would not trust the K&N filters in our application.

Wrong Walker here I am pretty sure.  Walker Engineering was started by Robert Walker, Sr and has nothing to do with the Walker involved in buses so far as I can tell.

[Jriddle]

Could be but other Walker has lots of stuff on several websites.

Sorry if I am wrong.

I think Sean has had the engine rebuilt twice for dirt ingestion, but I could be wrong.  Th ought once due to the filter and once when the intake tubing was loose.  I could only find one mention of K&N on his blog.  Maybe Sean will see this and set us straight.

    Belfert,

     Indeed  your right about the original engine,  I have know idea what it started out with.  The filtration system is 4 canisters, the

    large one you mentioned might just be the trick,  thanks!

Steve I understand you have just bought several different engines. Measure the intake air input to blower/turbo and compare it to 8V-71 I think you will find out the 8V92 is much larger. would recommend converting to modern stock Air cleaner of proper flow.
