compressor auto drain q?

[The Cobbler]

Several months ago there was discussion about an auto compressor drain. It was primarily a stainless assembly hooked into the unloader line. when there was pressure on the unloader the piston moves over, when the pressure unloads the piston moved back and drained the water.
can't find the thread now, any help appreciated
