Abstract
A vent fan is for directing a fluid along a vent pipe. The vent fan has a housing defining an inlet, an outlet and an internal space for a fluid flow path. A separating wall divides the internal space into an inlet and outlet chamber. The vent fan also includes first and second baffles to block the fluid flow from traveling into the outlet and inlet chambers respectively. The separating wall may also include at least one fin for directing the fluid flow towards a first passageway.
