One problem with using an air conditioner compressor for a vacuum pump
is that it would run hot, since air conditioner compressors are cooled
by the cold refrigerant that is pulled into the crankcase compressor
pump. It's also oiled by an ambient oil mist in the refrigerant vapor,
so I don't think it would last long, even if it was hooked up to a
vacuum switch that would shut it off when it was not needed to run.
Case in point: A couple of weeks ago I had to replace a compressor for
a new Ductless-Split air conditioner (those little rectangular Japanese
A/C's like Samsung, Mitsubishi, etc.) Someone had cut the refrigerant
lines in order to steal maybe $1 of copper, and the compressor continued
to run without being cooled oiled. In short order the compressor
burnt out and fouled with very smelly acid. IMO that's what would
happen with your window-unit vacuum pump.
A vacuum pump system isn't very expensive--I'd go with the right stuff.
I see used ones on eBay all the time. Every once in awhile Ed Berris of
skykingrcproducts.com sells some good systems, so you might check with
Ed through his website to see if he has any on hand he'd like to sell.
From what I've seen, he knows his vacuum systems well gives an
accurate assessment of the condition of his goods. (He's also a good guy.)

I have a 230-volt compressor motor that came from an old =
air-conditioning
unit. I understand that such a motor might be useful for making a
vacuum-bagging system, but I have no idea how to do it.
=20
Is such a motor what I need for a vacuum-bag system?
If so, how would I put it to such use? Can you direct me to a web =
source
for instructions? What else besides the motor would I need to build =
vacuum
system?
If this kind of compressor isn=92t suitable, what kind would be?

Thanks!
