debris. IMHO because its difficult to be certain these filters are clean
without disturbing them (ie dismantle) the daily preflight check of the
Andair is the safest bet, provided of course,that it isn't forestalled by
debris being hidden in the Purolators. Addition of these upstream of the
Andair IMHO reduces safety.<
I agree. I have always assumed the Andair gascolator is a replacement for
the filters and not in addition to them.
