When designing the GRACO expanding paddle mixer, the aim was to achieve efficient mixing and the possibility to quickly install the mixer around the circle. As the blades of the mixer are only open in the working position, it is also possible to use the mixer with smaller opening containers.
The mixer has an air motor with 1.75 HP, which can drive the mixer even with thicker materials. The mixer is made entirely of stainless steel, which allows it to be used with water-based substances.
