336 Stirrer Seals, Stirrer Shafts 1 2 3 4 6 5 Additional Blades The ideal addition to the company’s existing stirring shafts with a fixed stirring unit. Addi- tional blades can be freely positioned in height and direction of rotation on any shaft with a diameter of 8 or 10 mm (a matching fork wrench is included with each additional blade). The blades themselves are made of PTFE while the fasteners are made of a special PTFE compound. High chemical and thermal resistance is thus guaranteed. With this “building block system”, users can assemble their very own stirrers as required.
