How about reversing the differential pressure to backflush it, every
decade or so?

The manual showed a helix surrounding the bulb. It ocurred to me that it
might be acting as a resonant antenna, rather than just a distributed

The gas pressure in the small tank was increasing, hence it's being
compressed in the smaller tank. I know Lecture Bottles get warm while
filling to 2000 psi.
