Here are a couple pics of version 2.0 of the liquid/vapor separator.
It’s just two identical diptube traps hooked in series (or ATM as I like to say).
The single trap I was using before worked great. When I took it apart to clean you could see oil residue up to about 18" from the bottom of the trap, the rest was pretty clean. The diptubes extend down to about 3" from the bottom of the traps.
The overall height of one of the traps is about 42"(107cm).
I still noticed some very slight residue on the outlet fitting of the trap after 2.5 months of hard use so I decided to add the second one. I probably shouldn’t wait so long to clean it, but you know how it can be.
The trap is true 3/4" minimum orifice the entire way through, which is my goal (including valve orifices) for the vapor path on my new system.
In addition to the trap I make sure to never fill my collection pot above 50-60% to avoid unnecessary flinging of oil droplets as much as possible.
Also, I’m still NOT using any molsieve anywhere on my system and I haven’t had any issues in years.
The vapor from the collection pot/columns enters the trap in the upper right, goes down the diptube then up and out to the left, then down the second diptube and back up and out to the compressor.
