do you have a dip tube on the INLET to your collection?
if you’re dropping liquid into your collection at the same time you’re trying to suck gas out, you are entraining droplets of hash.
adding a 12" extension to the inlet on my 2015 PX1 solved hashed mol-sieves just as it did when I realized why this was happening on my Mk III terpenator.
the Luna I’m currently running could benefit from a similar extension.
@Graywolf can probably point you at the MK III design to show you what I mean.
When I had my (second) Mk III built, I used the same length dip tube on a 12" collection as had come with the 6" collection MK III the boss purchased.
that was wrong.
it took me a couple of years to actually understand and solve.
the tip from @Photon_noir is about slowing the velocity of the vapor, changing direction (by at least 90°, 180° is better), and giving the droplets something to collide with. which is the same concept as Liquid separator instead of molecular sieve
