I am not 100% sure on Bill's "Freeze control tank", I will take a guess that it is similar to a condensation tank used to keep water out of airtools/paint guns etc. when using an air compressor. i.e. a larger volume container, is attached inline with your hose and condensation/liquids gather in it to be drained away via a pitcock. Am I on the right track Bill?

Bill or Rowly, do either of you fellow's have a link to a picture/details on the rubber membrane diffusers? Thank you.
