HI Dave,
    AC Compressors need lubrication in the Freon.  If you
compress air there will be no lubrication, an the compressor
will not last.  There are a few compressors that have oil
seperate from the freon, but the Vanagon setup is not
one of them.  Also I would not add air to a propane tank.
Propane without oxygen is not dangerous, but mixing them,
you are making a bomb!  I would use an old freon tank.
Freon does not burn.
                                                     Eric
