I have a DNAx membrane system.  It has performed without a hitch.
I am using a Bauer Capitano compressor.  I use EZ100 oil.  I fill tanks from 
a cascade system and fill the cascade from the compressor.  When I run the 
compressor I always try to run it for at least several hours at a time.  The 
fewer cold starts, the less wear on the compressor.  I just rebuilt the Bauer 
(new 2nd stage rings, new 3rd stage piston assembly and new valves) after 
2500 hours of operation.  I have had no real problems with the system.

Safe diving,
