How often do you drain your air compressor?

We installed a automatic drain system operated by the pressure release for the head when it shuts off. When ever the compressor kicks off the tank spits out the water. This is one make . There are several you can find much cheaper. They also make them for your water trap.

Does it by itself automatically , No electric, Never worry about water again

All this does is get rid of water you introduced to your tank. It is only working right after the compressor kicks out.
The air in the tank is still condensing so its still making water. Its still hot air cooling down ( making water)
What's wrong with getting rid of it before it ever hits the tank?
