Static mixers contain internal vanes or orifice plates that bring about sudden changes in the velocity patterns as well as momentum reversals. These are principally identified by their lack of moving parts. It is used commonly for mixing of chemicals with wastewater. It is constructed from a variety of materials that ranges from plain carbon steel, through special alloy metals, to fiberglass and other non-metallic compounds. The selection of the material to be used for any application depends upon the fluid being pumped, and the chemicals that are added.

Static neutralizing bar is used to neutralize static charges on web and sheet materials. The devices are mounted within the process machine in proximity to the moving material. As the material passes by the neutralizing bar, the surface charges are reduced or eliminated at that point in the process. The static neutralizing bar produces both negative and positive charged gas molecules called air ions. These are free ions that are attracted to the charged surface. Positive fields attract the negative ions and negative fields attract the positive until the surface is in electrical equilibrium.
