1. A method of filtering a main fluid using a rotary fluid filter, comprising:
initiating a 360 degree filtration cycle by receiving a first portion of a main fluid at a front end of a first fluid flow passage extending through a filter body rotationally mounted within a housing, the filter body aligned with a first rotation position of the housing;
rotating the filter body in a rotation direction about a rotational axis to align the filter body with a second rotation position of the housing;
discharging, in the second rotation position, the first portion of the main fluid from a rear end of the first fluid flow passage, the rear end opposite the front end and the first portion of the main fluid having passed through a filter received in the first fluid flow passage;
rotating, the filter body in the rotation direction about a rotational axis of the filter body to align the filter body with a third rotation position;
receiving, in the third rotation position, a first portion of air through the first fluid flow passage;
rotating the filter body in the rotation direction about the rotational axis to align the filter body with a fourth rotation position of the housing;
receiving, in the fourth rotation position, a first portion of a backwash fluid through the first fluid flow passage from the rear end to the front end; and,
completing the rotational cycle by rotating the filter body in the first rotation direction back to alignment with the first rotation position.
