[Shop-talk] FW: Anode for compressor

[Matt]

Wouldn't the moisture in the tank provide the electrolyte and the rod laying
in contact with the tank provide the connection.  I realize eventually that
the interface would be subject to corrosion, but then isn't that true of every
connection to some degree.

For a sacrificial anode to work, it must be well connected
electrically to the object that it is protecting. The two metals
actually form a small battery with the water acting as the
electrolyte. A small current must flow between the two metals. So -
You need a good electrical connection between anode
& air tank, & also an electrolyte.
