Abstract
A filter system includes a filter assembly having an interior, an end defining a bypass opening, and another end for coupling to an air intake of an aircraft engine to permit intake air from the interior to enter the air intake. The filter system includes a bypass closure movable relative to the filter assembly between at least a first position and a second position. The bypass closure substantially covers the bypass opening in the first position to inhibit intake air from entering the interior through the bypass opening. The filter system includes an actuator coupled to at least one of the filter assembly and the bypass member to cause relative movement of the bypass closure between the first and second positions.
