Amsoil EAAU Air Filters - CFM flow assistance

[Unleashedbeast]

Hello all,

Need some assistance for those in the know. I've received some information from AMSOIL about their nano fiber filters, but I don't know how to change it to know how much flow (CFM) the filter is capable of at 28" H2O. Can anyone here perform this conversion?

Quote:
We do not have the test information for each individual filter. We performed ISO test 5011 with SAE coarse dust. The test was performed on EAAU4090. As far as the results we found that at 350 CFM the restriction was 2.2 inches of H2O, at 500 CFM the restriction is 4.7 inches of H2O, and at 800 CFM the restriction is 11.5 inches of H2O. Since the filters all use the same media the results will be comparable. There will be slight variations based on size of the filter.

I know that if you want to convert flow @ 12" H20 to 28" H20, you multiply X 1.53, @ 5" H20 use X 2.37. Those two fit fairly closely to what they gave you

Roughly speaking, that 800CFM @ 11.5" would be 800 x 1.53= 1224 CFM @ 28" H20.

I'd check to see how much bigger or smaller (area) the filter they tested is vs the one you are interested in.

You can find a chart, here:

Thanks for the info, and the link Jim.

That helps me a lot

Thanks for the chart Jim.

That would be a lot of air, and if I was like the nut jobs on here I would have to believe that just lets a "ton" of dirt in. But since it is Amsoil it is magic.
