Abstract
A main filter for an airplane fuel circuit or a fuel circuit for any type of mechanism, the filter having a first and second entry, which go directly into a chamber containing a filtering unit, the first entry receiving the fuel at a temperature essentially equal to that of the second entry which receives a hotter fuel which has passed through a heat exchanger. The filter prevents clogging due to ice formation on the filtering unit of the filter or at least inhibits such clogging. A fuel circuit using such a filter is also disclosed.
