Anyone have a guess at this filters micron rating?

[Sidewinded_idi]

its an old military filter I acquired from g&j aircraft in Ontario. The element is serviceable but I can't find any info anywhere on it and I'm hoping maybe someone might know what it filters down to or rough estimate? I will be using it on my pneumatic suction pump for pulling wmo from shops. The discs are stainless steel media about 3/16 thick each

What type of media does it use? Other then stainless discs?

Might have better luck in the alternative fuel section too.

 

[Sidewinded_idi]

Just the stainless discs. It will go through this first, then a paper hydraulic filter element but I'm hoping this'll catch most of the stuff to keep replacement element cost down

Is it some form of stainless mesh? It'll be hard to say on micron rating without knowing how tight the weave is and such. Do you have any pictures of the actual discs?

my wag is 40 or 50 micron mesh kind of like the Oberg oil filters are.

I've worked with similar aircraft filters. They were for jet fuel and had a 5 micron rating. Oil filters had a higher micron rating.

IME, a filter this fine will plug up immediately when trying to suck cruddy wmo through it, and will be a pain in the *** to clean. I used blue jeans for first stage screening of aviation oils, which were very clean to begin with, and the jeans would clog up quickly.

Thanks some of the findings I've found suggest it may be around 5 micron. I pumped 50 gallons through it today!

This is labeled fuel filter so 5 micron sounds about right

I'D say about that much.....

Had a double 5 micron filter setup when I was burning WATF back in college years ago. Seemed to filter pretty well but there would be a lot of black sediment on bottoms of my 5 gal tanks, so it wasn't getting all the crap out.
I eventually ruined all 8 injectors, IP, & carboned up precups so bad I had to use a chisel and vacuum to break it apart inside head. Thought I was saving money .
Definitely get a centrifuge if your going to burn wmo in your engine. 5 micron filter isn't enough
