An apparatus for the injection of a fluid filler material includes a static mixer (1), with the static mixer including a housing (2) which includes a first hollow space (47), with at least one mixer element (3) being arranged in the first hollow space. The housing (2) has an outlet element (45). The outlet element (45) has a second hollow space (48), with the second hollow space (48) being connected to the first hollow space (47) such that the fluid filler material can be conducted from the first hollow space (47) into the second hollow space (48). A tubular element (60) is held in the second hollow space (48).一種用於注射流體填料的設備，包含靜態混合器(1)，該靜態混合器包括殼體(2)，該殼體包括第一中空空間(47)，至少一混合元件(3)配置在該第一中空空間內。該殼體(2)包括出口元件(45)，該出口元件(45)包括第二中空空間(48)，該第二中空空間(48)被連接至該第一中空空間(47)，使得該流體填料可被從該第一中空空間(47)引導進入該第二中空空間(48)內。管狀元件(60)被固持在該第二中空空間(48)內。
