The unit I purchaed is the one that has the three different types meda material within it. Does it have a specific flow direction as it is placed from compressor to rifle.
Thanks for the help

It is likely that one of the three is charcoal, and that should be the last one that air flows through, so put it closest to the gun. In truth it does not matter much for our use, but that would be the way it would go for breathable air . . .

I agree with AlanMcD that it does not matter much for air you do not breath.
If it were me, the male fitting would face the compressor with the female toward gun.
But no matter what you decide, do a dead head test before you start filling guns.
I don't know if anyone else has experienced this, but I am 0 for 3 with TUXING filters in the last 5 weeks.
Usually good, their quality control seems to have gone out the window lately
Just my too sense

I was just looking over one of the smaller filters and noticed rough edges where the oring should seal, I bet that is where that one leakes
I just use cotton in the small filters, the large I use a moisture asorbing sive bead.Upvote 0
Manual states inlet is male foster fitting, outlet (to gun or tank) female. Plastic insert should be positioned so desiccant beads towards inlet end, activated charcoal towards outlet. WM

In any of these Tuxing filters, the o-ring sealed end cap is always installed on the outlet side. The non-sealed end cap is always installed on the inlet.
The reason for this is the non-sealed end cap allows incoming air to "leak" into the space between the plastic cartridge and the inner walls of the pressure vessel. This assures that the air pressure is always equal on both the inside and the outside of the plastic cartridge.
One should never open a connected pressurized tank valve until the compressor has pressurized the filter to equal the pressure in the tank. If the filter is pressurized from the tank, the o-ring seal will not allow the air pressure to equalize on both the inside and outside of the plastic cartridge and likely cause the cartridge to fail.
When I received my Tuxing cartridge filter, the cartridge was configured such that the charcoal section was installed in the inlet side. It was a simple process to reverse the end caps and reinstall the cartridge in the pressure vessel.

Now you all are going to find out just how new I am to PCP-What is a dead head test?-does that mean to see if there is air flow through the filter before attaching to gun. I do not have a tank at this point.

Jack, Thanks, knew about one end being "O" ringed, never considered why. Now I know and makes sense. WM

Dead head pressure test is conducted to find air leaks in the high-pressure air (HPA) filling system. Inserting dead-head plug (pictured) in female quick-disconnect fitting at end of fill whip (hose), pressurizing, shutting down compressor then using soapy water spray bottle to search. ALWAYS RELEASE PRESSURE BEFORE RESTARTING COMPRESSOR. WM

Often dead-head pressure tests are conducted when filling times increase for no obvious reasons. Others establish a baseline, thru dead-head testing, to record the time it takes to reach a designated pressure. Subsequent tests, with fill times longer than baseline, could be an early indicator of problems. WM
