Abstract: An air management device for a filter assembly includes a top portion, a bottom portion, a plurality of frame members that connect the top portion to the bottom portion so as to define an inner cavity, and an air management valve. The air management valve includes a base portion, an intake valve, and an exhaust valve. The base portion is provided at the bottom portion. The intake valve extends into the inner cavity from the base portion towards the top portion. The intake valve includes an elongated opening that extends along a longitudinal length of the in-take valve. The exhaust valve extends into the inner cavity from the base portion towards the top portion. The intake valve is configured to intake air through the elongated opening and the amount of air introduced through the elongated opening varies based on a fluid level present within the air management device.
