One of those automatic drain valves is also a plus if you can stand it going off every 45 minutes and causing you to jump out of your skin. After a couple of years I'm finally getting used to it. But my wife still shrieks if she is in the shop when it drains. She is sure the end has come.
That idea was expressed to Franz, the designer of this thing and he states that while a second tank is sort of a Franzinator, it does not accomplish the same objective. The design is made to cool the air by forcing the air downward inside the 2 inch pipe and causing the air to stop for a short moment and that stop causes the moisture to drop out of the air. As the air rises in the pipe, it then cools and cools more as it goes into the 3/8 inch tubing. You will notice quite a difference in temperature between the lower part of the Franzinator and the top part. The tubing to the tank and the tank itself is way cooler than before.

There has been huge heated discussions about this device on the internet and for the most part, any attempt to change the design has been a failure. There is also a plan for an air polisher which gets rid of the rest of the moisture. It is a second smaller tank with tubing inserted and a drain. I'm debating weather to add that as my air dryer/filter is now lasting a lot longer than it ever did.

All I know is that this device works. I followed Franz's design to a T and it does do what he says it does. I hear the gas companies use a device similar to this to remove moisture from their gas lines.
