I work with vacuum in the 1x10^-7 all the time - vacuum manifolds evacuated with turbomolecular pumps.

Back in the days when I did organic chemistry synthesis, we would often dry our liquid reagents with molecular sieve. The water would get bound to the mole sieve and we'd regenerate it when the bottle of reagent was empty. How? By putting it in a vacuum oven. We'd pull a fairly strong lab vacuum via lab vane pump, then heat the oven to 70 degrees Celsius. This would drive all of the water out of the molecular sieve. Just vacuum or just heat will not regenerate molecular sieve. Silica gel media also does not regenerate in just vacuum or just heat. Pretending that this process is fully reversible without additional treatment is ignorance at it's best.

I'm guessing that wwest got the hook because he was bashing Griff.

He'll be back with his same old abusive crap, except avoiding bashing Griff - we'll still have to put up with his stupid lies.

I hope Bob is successful in getting wwest canned for good. Bob - as a moderator on an Audi site, don't ask for moderator status. You might get it, and there's just about no volunteer job worse in this world.

And I went 10^-8 Torr with 2 36 inch diffusion pumps (no expanding "voids" in there!) coating telescope optics. You know just as I do that even moderate vacuums like an A/C system are not defined by how much a pump can "suck" stuff, since that's not how vacuums work.

Yes, one could take a used receiver dryer, put in into a bell jar, pull a hard vacuum, then heat the whole thing to 150 degrees for a few hours, and you might recover the silica enough to be useful, but for the $20-50, WHY would you?

[brads911sc]

Im sure the idiot wwest will come up with a reason and a solution. Maybe something that involves switches and spal fans.

Two professional working with vacuums both say the same thing. I bet Wwest will still argue his faith in his gut "knowledge."

Every AC book I have ever read says replace the receiver-drier if the system is open for very long.

[brads911sc]

he is a troll. Argues for the sake of the argument. nothing factual in 99% of what he says. Needs to be banned for good and sent back to the ford/ecoboost boards.

Exactly. The expended time and effort in order to revive a spent receiver-drier isn't worth it. Even the most expensive R-D cartridges are stupid-cheap in comparison to a vacuum oven. You could buy 20 or more receiver-drier cartridges for the cost of a used vacuum oven. And the time and effort spent to do it...

wwest doesn't understand the principles behind working with vacuum, let alone the physical aspects of the vacuum pumps themselves. Hydrated crystals are not just water molecules stuck to a surface, waiting for a pressure drop to come off - a chemical reaction has occurred there. It takes significant energy input to reverse the reaction.

Better to just buy a new RD.

^^^^ But what if you placed the used RD in front of a spinning 964 engine fan - would that work?!?!?!

I can't believe they let that guy back in. It would be nice if we could just vote him to ban island permanently. Should there be a thread on this forum that would poll the users (that doesn't sound right!) on whether Wild West should stay or go?

If you have ever tried to dry out a system that had flooded with water due to a tube failure (water chiller or water cooled condenser) you would be surprised to find how long it takes to remove that water. Setting up cold traps to intercept the moisture before it contaminates the vacuum pumps oil charge is another interesting proposition.
The above posters are absolutely correct about trying to save a receiver drier open to atmosphere for any length of time. Just buy new.

Not if the fan has straight blades.

It sucks is because you actually moderate.

Willis gets a wet spot in his pants when we get pissed off.

We are the fools.

I'm not sure if the 964's fan blades are "straight" or gay, but I suppose that depends on who's driving the car!

So many new videos for Willie to post...

I just finished converting my 82 to 134 from R12. I bought a new Sanden comp. and had one hose made from the comp/. to the fitting above and an adapter from the existing hose to the comp. I had the fill fittings installed into the hoses. Just remember they switched sides on the fill fittings from R12 to 134 as to the size of the fitting. Do not ask how I discovered that. I had these hoses and adapters made at a hydraulic hose shop not an A/C shop. System seems to be working OK. Tom

In Ohio, "working OK" is enough.

My Mom was born in Perrysburg (She was really, really young when it happened)

Status back to banned. Hope that is done.

True. And you never make any friends that way. Only enemies. And forever.

OMG - That is beautiful. I played my last hand with the Heads of State from a common sense standpoint.

No PM's from Wayne on moderator status :-)

Although, I would love to do it and the offer is still there.

I'm gay. All my wives say so. And my kids.

Ronnie wants to buy this car cause the rear end looks like a 904. He says no one will know it's an Opel GT.

Love you bro!

[SilberUrS6]

LOL, Bob, just LOL.

Seriously, I don't think you want to moderate. It really does suck hard. I'm sure you'd do well, but if I had to do it again, I'd tell the website owner to take a flying leap when he offered me the job.
