I have been contemplating building a vac press system in a little while
so maybe you can answer my question; I have a fairly large window AC
unit I am not longer using, is the compressor in this [generally]
suitable? i.e. I know you cannot answer my specific case, but do AC
units generally generate a similiar amount of vacuum as a refrigerator?
Otherwise I gotta get to selling the d**n thing cause it is taking up
room in my shop...
