A lot of you would know this if you've been in the game a while, I don't mount any of these aerators from their factory mounts. The factory mounts are simply terrible to work with:

  1. they deteriorate in time due to the heat of the compressor 
  2. the vibrations of the units as small as they may be could be resonated thru walls and its heard from afar

Use some Bungie's and hang them from something, it makes the vibrator way stealthier, zero vibrations and you won't ever have to take care of it after the mounts break. Plus, it’s as quiet as a mouse church when it operates.
