Help interpreting Wix beta ratios?

[mva]

The Wix web site provides micron ratings and beta ratios for their filters. Here is an example of a common Honda filter:

Part Number: 51334
UPC Number: 765809513341
Principal Application: Acura (88-05), Chevrolet (85-88), Dodge (91-96), Ford (88-96), Honda (72-09), Hyundai (89-09), Isuzu (85-04), Kia (01-09), Mercury (87-91), Mitsubishi (89-98), Subaru (87-09) Atlas-Copco, Case, John Deere, Kobelco, Komatsu, Kubota, Onan, Toro & Yanmar Diesel, Other
All Applications
Style: Spin-On Lube Filter
Service: Lube
Type: Full Flow
Media: Paper
Height: 3.194
Outer Diameter Top: 3.252
Outer Diameter Bottom: Closed
Thread Size: 20X1.5 MM
By-Pass Valve Setting-PSI: 8-11
Anti-Drain Back Valve: Yes
Beta Ratio: 2/20=22/40
Burst Pressure-PSI: 280
Max Flow Rate: 9-11 GPM
Nominal Micron Rating: 19


How do I interpret this info?

Wix 51334

Nominal rating = 19 microns

Beta Ratio 2/20=22/40

From another website:

http://www.noria.com/learning_center/category_article.asp?articleid=564

I am guessing:

Beta 2/20 = 22/40

means 50% multipass efficiency at 22 microns and 95% multipass efficiency at 40 microns.

This doesn't look very good to me and I am wondering how they can call this a nominal 19 micron filter.

Is my interpretation of the beta ratio correct?

 

[Gary Allan]

Yes. You have it correct. The notation is non-standard, but easily reasoned. Beta ratios TYPICALLY fall into 2/20/200/1000 (whatever) but RARELY do particle results at a given ratio fall into such order. They're all over the place ..9 .17...23..34..etc. There are exceptions ..but I've never seen it in automotive applications. Hydraulics or fuel may have some 10um spec ..so the beta ratio may be an oddball (not too common).

The 19 nominal is the single pass result.

What is the oversized equivalent for this Wix filter 51334 ? Ideally, the outer diameter and gasket should be the same sizes but the height (or length) should be about 1" or more longer. It would be used for '04 Honda S2000.

 

[Gary Allan]

I dunno if you can truly get bigger here (thinking). I think you can get longer with a skinnier can (2.6x diameter).

Donaldson has one or two ..but I don't see a bypass valve noted. It doesn't xref to WIX

I'll check the Amsoil master cat later ..but I'm sure I've been here before.

The 51344 looks very close. It's an inch longer. The gasket OD is 2.49 instead of 2.475.

Ahem, Donaldson.... Ahem........

The (huge) P559000 (synteq media) claims:

85% 10-micron efficiency at 150lpm
89% 10-micron efficiency at 105lpm

10μ Efficiency per ISO 4548/12

Seems to me, that would be why Amsoil licenses it eh?

 

[mva]

Thanks for the responses.

I just checked a few more filter ratings for comparison:

Fram Toughguard TG3593A 99% Multipass Efficiency at 20 microns

Amsoil 98.7% Multipass Efficiency at 15 microns

Commercial heavy equipment would/could be one such exception to the "TYPICAL(LY)" assertion.

Ahem ..

You can find filters that have specific micron spec's (like 10um etc.) there you can get oddball beta ratios.

And Donaldson isn't unique in this. Baldwin has quite a few with (something like - pulled out of my behind) Beta14.3=20.

Yes, the issues with getting a filter like that is of course the limit of available filters that cross to automotive applications. I believe the last time we covered this, it was Ford FL1A/Dodge and GM SBC filters that they made them in. That was it.
