Outerwears

[sparks57]

I did more searching in the archive and I came up with another question...



I came across a few minor references to this "outerwears" prefilter. I have only heard of it being utilized with the BHAF.



Is it only usefull with the BHAF because of the water deflection properties? Or is it a good investment for all filters (like afe for example)? Or are there other advantages also?



Thanks.

CB,there are two types of outerwears one can use. One is the foam type. This one can be coated with a water repelling oil which will stop the water and trap dirt. But at the cost of air flow. It would be my first choice in a dusty inviroment.

The second is a nylon type that will not stop water, and dirt and most dust bounces off. It flows a lot more air than the foam type but at the cost of no water repellant. The K&N outerwear only restricts 10% of total CFM.

Most air filters will do a great job unless you live in a very dusty location. And both types of outerwear must be cleaned twice as often as the regular filter.



This help?

The polyester OUTERWEARS that I have on my BHAF says that it is water repellent and is designed to... "... prevent splashes of water or mud from saturating your air filter" their number is 800-967-3450 the part number for the BHAF prefilter is WR3325-105 for Fleetgaurd AH-19037 ( this is not a foam type and requires no oiling)

I also have the thin one which is supposed to be water repellant. It may not be *waterproof*, like if you immersed the thing in water, but it definitely does repel water--it just beads up and rolls off, just like on a pair of cheap polyester pants.

I'm using the thin Outerwears cover on my BHAF. I washed it the other day and it did a fine job of repelling the water. Even after dunking it in a bucket all it needed was a shake. If your location under the hood is somewhat protected I think it would be safe. In extended driving in the rain??Perhaps someone has done that?

I'm sorry, I should have used the word "polyester" instead of nylon. They are run dry. And yes, water will fall off when not in use. But, factor in the draw that a Cummins creats when running and that water will flow through it like a red hot knife through butter. I've tried all the products available and there is no pre-filter that will flow the air you want and protect you at the same time.

Run one in the desert or sand dunes or mud and look inside. But I do run one if I'm in these invironments. The power loss costs less than a motor.
