Here is the unboxing photo.
This one came with a plug already installed in the bottom tank and a bag of 6-32 long and short screws.
A closer look at the end barb plenum tank using Swiftech barbs shows that the insides of the chambers are tapered and you can see the divider in the middle to force the water down one side and back up the other side.
One more of the barb plenum. The acrylic end tank is attached via copper tabs that were bent down into place and forces the tank against a sealing gasket.
Turning it over to look at the bottom tank and you will find an air/bleed screw. The screw is also acrylic which makes removal a little more tricky since it’s hard to turn the screw out without causing some marking of the screw slot. Here you can see the copper part of the end tank tubes has been soldered then copper plated over that solder.
This is actually the HD model, but the acrylic version had a similar logo imprinted in the fan shrouds.
I measured roughly 12.4 folds per inch across my usual 5″ check photo. This is a fairly low density which should be tuned for lower speed fans.
The fin spacing build quality was generally good, but there were a few marks in finishing of the clear coating. As far as durability, it seemed to hold up fine during the limited review testing time frame and general handling although this has been a very limited test run and I’m unable to report on the acrylic durability. Per the elegant website, it notes something about a revision 2 with nylon/fiberglass as an end tank, so there may be some stronger materials options available.
