• a housing having at least one outlet opening for air to exit the gear pump, the at least one outlet opening having at least one inlet and at least one outlet;
• a first gear disposed within the housing, the first gear having a set of first teeth with a plurality of first roots, the plurality of first roots defining a first root circumference;
• a second gear disposed within the housing, the second gear having a set of second teeth with a plurality of second roots, the plurality of second roots defining a second root circumference, the set of second teeth mesh with the set of first teeth upon use of the gear pump;
• and
• at least one gear shaft about which the first gear rotates or the second gear rotates;
• wherein the at least one outlet opening is situated adjacent the first root circumference, or adjacent the second root circumference, or adjacent both the first root circumference and the second root circumference, wherein the set of first teeth have a plurality of first tips and the set of second teeth have a plurality of second tips, the at least one outlet opening is situated in the housing to communicate with a first clearance established between a confronting first root and second tip, or with a second clearance established between a confronting second root and first tip, or with both the first clearance and the second clearance upon respective establishment of the first and second clearances.
