If Mr. Google cannot find it that is most likely a hint - unknown product, unknown history, unknown problems, etc. However, to answer your question directly, I have never heard of it. Maybe it is a one off project by a guy named Rich Porter? Dunno.
Thanks Bob. That is what I am thinking too. A couple days ago I found a reasonably priced ElectroAir and purchased it instead of the Richporter.
