Embodiments of the invention provide a ventilating system including a housing. The housing can include an inlet through which air can be received within the housing and an outlet through which the air can exit the housing. The housing can include an inner surface and an outer surface and an electrical aperture. A fan can be supported in the housing and it can be operable to generate a flow of air. A panel can be coupled to the housing adjacent to the electrical aperture. The panel can include a clamp aperture and can be coupled to either the inner surface or the outer surface. The panel can also be coupled to the housing so that the clamp aperture is oriented either substantially parallel or substantially perpendicular to the inlet.
