Bhaf II ??

[Ncostello]

I saw an air filter in the Napa catalog today that was sort of interesting. It was the 6469. (A-116 series). It was a cylinder shaped unit very similar to the BHAF. But with a twist.

The overall height (or length) was 11.880", same as the Napa BHAF. The OD was 10.500", same as the Napa BHAF. And it had a 4" hose connection, same as the Napa BHAF.

Well, what is the difference you may ask???

The filter is fully contained in a metal housing (cylindrical). So the filter inside it must be slightly smaller than a BHAF if the outside dimensions of this metal housing/filter combo is the same as the BHAF filter itself.

This unit is identical to the throw-away units on our ISC 330 powered fire engine...only smaller. Ours for this rig are $190 each.

I'll try to explain it best I can. Imagine a BHAF within a metal cannister. The turbo hose hooks up to same location as a BHAF. The air comes in through another 4" round opening on the side of the cannister. It says you can hook up the turbo hose to either opening. Flows both ways. Both openings are 4" diameter metal tubes.

Looks like a 10.5" round muffler with the outlet on the side.

Only thing is though, I have no idea what it would flow. Cost = $48
