1. A water collector configured to remove moisture from air flow output from a line replaceable unit (LRU), the water collector comprising:
a housing extending radially about a center axis to define an annular profile with an opening configured to receive the LRU, the housing having an inner surface that extends radially about the opening and has a diameter defined by the profile of the opening,
an upper portion including a coalescing unit having a collector inlet defining inlet air path extending along a first axis to receive the air flow, and configured to coalesce moisture from the air flow output from the LRU and including an outlet flange on a side of the upper portion, the outlet flange having a torus profile that defines a collector outlet downstream of the coalescing unit, the collector outlet defining an outlet air path extending along a second axis that is orthogonal to both the first axis and the center axis, the collector outlet configured to expel the air exiting the coalescing unit along the outlet air path; and
a lower portion including a collection unit downstream from the coalescing unit and in fluid communication with the coalescing unit via the inner surface, the collection unit configured to collect the moisture coalesced by the coalescing unit,
wherein the coalescing unit the coalescing unit has a helical air passage defined by an inlet channel including at least one axial swirl vane including an upper portion extending into the inlet channel and a lower portion extending into the collection unit.
