Abstract
A grease containment device for an exhaust fan is provided. The device includes an outer housing and an inner housing. The outer housing defines an interior receptacle, a first end surface, and a second end surface opposing the first end surface. The first end surface includes an inlet to the interior receptacle for grease from the exhaust fan, and the second end surface includes a sloped drainage surface leading to at least one drainage opening. The inner housing is located within the interior receptacle and includes a quantity of grease absorbent media in communication with the inlet. The grease absorbent media is hydrophobic, and the inner housing includes a porous portion proximate the sloped drainage surface.
