Yes I know, but it does depend on what's tested and under what
conditions. It would be pretty difficult to stage that
comprehensively.

It rather reminds me of those in line magnetic devices that attract
sludge particles out of the water rather than their being deposited in
radiators.

Mr Whetstone's invention undoubtedly works to remove air from CH water.

However, like the magnetic thing, it's addressing the issue in the
wrong way - i.e. fixing the symptom, not the cause. It's reasonable
to have an air separator during filling and for a few days afterwards
white the dissolved air is driven from the water. After that, it
shouldn't be needed. If air is still in the system, it has to be
entering somewhere, or it may be hydrogen.

The plumbing arrangement for this embryonic frog device is the same as
for a simple one like an Aerjec at a tenth the price. Fitting one
forces the plumbing to be corrected such that there is minimal pressure
difference between the vent pipe and the feed/expansion pipe. If
that is done, then the major reason for air entering is removed anyway.
