The duct extends horizontally within the tank adjacent a side wall the recovery tank for directing air and liquid from the inlet opening in two opposing directions. A lid covers the tank and has an outlet opening for directing air out of the recovery tank.

The outlet opening of the lid is located between the shields such that the shields prevent liquid from coming out of the duct and entering the outlet opening of the lid.
