In an example embodiment, a router that is configured to pass a pneumatic carrier therethrough and comprises a solid continuous curved tube, a tube rotational support, and a drive. The tube includes a first open end and a second open end opposed of the first open end. The tube rotational support is in operative supporting connection with the tube and enables the tube to rotate about an axis. The first open end is generally aligned with the first opening. In a first rotational position of the tube, the second open end is generally aligned with a first of the plurality of second openings. In a second rotational position of the tube, the second open end is generally aligned with a second of the plurality of second openings. The drive is operative to cause the tube to move between the first and second rotational positions.
