An aerosol delivery device cartridge filling system, comprising:

• an assembly carriage comprising a plurality of receptacles configured to respectively receive a partially-assembled cartridge including a flow director, the receptacles each including an aperture extending through the assembly carriage;
• a filling apparatus configured to dispense an aerosol precursor composition into the cartridge at one or more of the receptacles;
• a manifold comprising a plurality of cooperating outlets configured to align with at least a portion of the receptacles;
• and
• an air supply configured to supply a flow of air into the manifold, out of the manifold through the cooperating outlets, into the aperture at each of the receptacles aligned with the cooperating outlets, and through the flow director of the cartridge while the filling apparatus dispenses the aerosol precursor composition.
