A212CW Filter screen

Re: A212CW Filter screen

Hello All,

FWIW, my '71 LT-1 when I purchased it in the early '70's came with the square design (horizontal/vertical) and replacement filters I purchase for it from GM in the mid-70's were of the same design.

Having said that, I was not the original owner from new, so I can't say what it came with new, but I do know the square design in the link Scott provide to Paragon, was sold by GM during that time.

Kurt,
73...1980 AC was making square mesh filters, so if the OO changed the filter and you bought them from an AC SP outlet or a dealer...you would get the square mesh.

I know of one, one owner 72 and that OO has underhood pics when the car was new, diamonds... even he bought filters in the mid 70's which he still has and they are square.

Re: A212CW Filter screen

One thing that I wonder about is if the early design was the "diamond"design and the later was the "square"design.Why would all of the replacements made from the late '70s to present be of the earlier "diamond"design instead of what supposedly was being made at the time the "square".Would that not create a need for retooling? I do not see that happening from a manufacturing standpoint.I also cannot see why the manufacturer would make an old design to sell as a new part.Another thing that I looked at was my judging sheet for my 1966 at my first NCRS event in 1977.I was dinged for a "replacement air filter".In the notes it is written that"the mesh should be square design.What did I know I was a 19yr old kid.Now heaven knows that there have always been judging mistakes.There still are!

Not necessarily "mistakes". Perhaps oversights happen from time to time. The NCRS judges make evaluations based on the written information provided to them that is current at that time. It is certainly no easy task.

Why did they return to the "diamond" design after using the "square" design for so many years? Very simple. The "diamond" mesh screen used for most of 1965 through about 1969 was a soldered-wire type screen. The "square" design screen used from about 1970 to about the early 80's was a soldered wire type screen. The "diamond" mesh screen used from about the early 80's to the present is an EXPANDED METAL type screen. It's not practical to manufacture expanded metal type screen in anything but a "diamond" pattern.

Caveat: it's possible that some very early AC 212CW elements (like from 1965) also used an expanded metal type screen. I've never been able to confirm this one way or the other. If they did, though, they would have been expanded metal with an OIL-WETTED paper element.

It's too bad I need this for my Camaro. Otherwise, I would sell it, pay the house off, fund the kids college educations, buy a new Caddy and quit my lousy minimum wage job.

Do I see the raised AC 212CW on there?

Re: A212CW Filter screen

For sure, brother...it's hiding on the backside.

Sometimes I wonder if I'm truly a dope and then something happens to prove my suspicions.

I've owned this filter for a number of years and was under the impression the embossing was only on the backside. Then you made the above comment and I looked at the picture and sure enough, there appeared to be embossing on the front as well.

I thought I saw something there on top, but given my eyesight you could have convinced me otherwise.

Mark, and fund my kids schooling too

A couple notes back, mesh...

Up to and including 68MY, all round wire woven mesh, on a diagonal, but these are not diamonds.

69CY would begin the experiment in diamond expanded metal and if you have one as Mark indicates, Camaro's rule, you pay off your house loan, or send the kids to college.

After the horizontal round wire mesh finished, you would then see what is very available these days in the second and third versions of expanded metals.

Time wise they lay out cleanly with other details on the filters to help corrobate the time of manufacture.

Some of us do that for a very long time.
Don't get me started on that subjet.

I will just say: "The only thing more expensive than a good education is NO education. And you can take that to the bank.

Re: A212CW Filter screen

Speaking of bad eyes...Mark's avatar looks more like a CRJ to me than a Camaro, or a Corvette. I have a sneaking suspicion he does a little better than minimum wage if he commands one of those. Good on ya, Mark (retired Air Force myself, rotary forever!).

Piedmont Airlines Boeing 727/200. Flew it, loved best of anything I've ever flown, wish we had em' back.

As a Captain it was voice activated. If you said you were cold, the cockpit would magically heat up. If you said, I would sure like to have a cup of coffee, one would magically appear over your shoulder...great airplane.

Re: A212CW Filter screen

Wonder if that is a old Northeast via Delta sold to Piedmont because they were close to the end of their useful life. They had pneumatic pressurization systems they were a nightmare to maintain. Was one the bests days for me at Delta to see them gone.
