The filter I used for my original Yong Heng 300 bar compressor was a Tuxing TXF003 L350mmxOD49mmxID36mm which can be found on that particular sale’s website. It will come with a repackable insert containing Mol. Sieve and activated charcoal (which is not necessary unless you are using it for breathing air- which I would not rely upon). For you to repack forget the charcoal and source some 13x Molecular Sieve “pellets “ which you must store in a absolutely dry well sealed container prior to use. When repacking make sure it is not loosely packed same as the original setup as you don’t want the incoming air to skirt around the pellets. Molecular Sieve needs to work at high pressures so don’t open the valve to the air bottle until about 2000 psi/160 bar. I add a few silica gel blue moisture indicating beads to the MS to indicate when the filer needs repacking; silica gel is nowhere as good as MS! A point to keep in mind is that the Chinese use M10 threads on their fittings which is close but not a replacement for 1/8 unf. However, Best fittings have M10 fittings to foster and using one of their fittings I installed a one way M10/foster so I could “blow down” and exhaust water from the compressor without losing built up pressure in the filter. But, remember you must be able to release pressure on the air bottle side(filter included) when finished. Also the foster fittings on the filter must be well sealed to the atmosphere when finished. A point to remember is that sometimes Chinese foster fittings are “ shall we see say not quite on par with Best Fittings”) I replaced my fittings on the output side of my compressor with Best Fittings including a micro bore air line. It is important to blow down your compressor regularly when running to expel as much liquid water as possible prior to the MS filter. Finally, this is important, the filter must be mounted in a vertical position, input downward and output upward.
