Anyone used this with success in a 617 powered SD?

Never seen one. Interesting pitch though.
What debris would be damaging to the compressor that doesn't come from the compressor?
Looks to me to be another point of failure, a restriction point increasing pressure, etc..

Usually after a compressor failure an in-line filter is installed. I've only seen that on commercial or residential units though. I have never seen one on a car.
I certainly wouldn't just put one in just for the hell of it.

Commercial and residential units tend to be fitted with Sporlan "Catch-All" filters, rather than a simple screen filter.

One good reason to use one of these screen filters is to replace a muffler.

After reading a lot on Aircondition.com...and looking at my house system... and having built from scratch ( three piles of random ac parts) a working AC for my karmanGhia... I believe in inline filters....but usually the ones I have seen were a couple of inches in diameter and three or four inches long... thus would not have provided a restriction in the fashion this particular example would seem to do...
I am going to put one on my car downstream of the compressor just for the protection of the condenser... They do not have to replaced every time the system is opened up like the receiver/dryer does...so they have the potential of being a life time addition only needing replacing if the compressor goes to ' Black Death' status...

You could ask the same question about your engine oil filter. Just like the engine, the compressor is not immune to damage from self-generated contaminents.

Just like any other type of filter.

I used that universal filter on my '83 300SD when I put in a new compressor. It did not suffer black death - the bearing was just squeeling. I can't say it has really protected anything but it sounded like a good idea. I also thought it may help me with any warranty issues.

I spliced it into one of the hoses (in the straight metal portion of the hose) by the ac drier. However, I had to make the ID of the compression "ring" a bit bigger because it would not go over the metal line. Otherwise it was easy to install.
