Check with an a/c pro on this, I read in a recent  post that using anything
but nitrogen as a flush agent  will  contaminate freon . I dont recall
whether this includes 134.  Compressed air also is a no-no because of the
ambient moisture.   MP. The post was addressed  those in the trade
who  are not all on the same page re  flushing.   MP.
