Abstract
A vacuum nozzle includes a main body (12) and at least one auxiliary body (22). The main body has a first open end (16) and a second open end (18). The first open end is coupleable to a vacuum hose (2) and the second open end is configured for receiving materials to be transferred. The auxiliary body (130) has a first auxiliary opening (136) and a second auxiliary opening (138). The first auxiliary opening is positioned closer to the first open end of the main body than the second open end of the main body. The second auxiliary opening covers a portion of the second open end of the main body. The auxiliary body provides a dedicated auxiliary passageway for providing a consistent flow of air to the second open end of the main body when the vacuum nozzle is in use.
