reduces pressure Drop by 50 percent

johnson screens improved inline mixer utilizes a unique internal design, which uses ordinary line pressure
to create high levels of turbulence, enhancing the mixing of fluid additives with the product stream. With
no moving parts, the inline mixer is virtually maintenance free and installs quickly and easily with no special
tools or additional components. These inline mixers are used in a wide variety of processes, such as
chemical blending, pH control, water treatment and chlorine mixing.
This new model of inline mixer has some
distinct advantages compared to earlier
models:
• Handles higher flow rates
• improved mixing performance
• reduced energy consumption
• Larger wrench flats
• reduced backpressure during
operation
standard features of the inline mixer include:
• pvc construction, with stainless steel bands, aids in chemical compatibility
• clear pvc sight tube allows easy viewing of the mixing process
• Standard 1 in. male NPT threads on the inlet and outlet ports
• Standard ½ in. female NPT threads on the injection port

The triple turbine (patent pending) in the new
inline mixer model induces the turbulence

needed for increased mixing performance
with a decreased differential pressure. This
triple turbine changes the directional flow of
the fluids, allowing mixture prior to exiting
the mixing chamber.
