Hi! Graham
Just a little alarmed with your statement questioning the suitability of
the Mini-Andair gascolator. I used a single unit throughout my Jabiru
3300 heavy fuel use experiences with no problems other than those, not
Andair related, manifested by the damn tank comnector finger filters
and drillings.
I now have two Mini Andairs on each fuel line so theory has it that one
should remain gunk free for the emergency situation albeit with a 914?
Clean system flows were well in spec. before flight testing.
Regards
Bob Harrison G-PTAG

a lot of good sense in what you say.
The Andair gascolators have 120 mu mesh, because Rotax specify minimum
of 100mu filters. They couldn't buy 100mu at the time I discussed it
with them. Those nice Mr Funnel filters are around 70mu (if I remember
right) and they WILL allow dust through that will block an Andair Mini.
I know of one blockage with a 914, caused by rust from a Jerry can. The
Mini is probably OK for 912S but not 914 with the high recirculating
flow rate.
