H2O Rx custom build a range of static mixers - wafer-style, variable flow, low headloss, and open channel mixers - in many materials and sizes to suit fluid applications in most industries.

K Value (kV) for headloss coefficient, Coefficient of Variation (CoV) for amount of mixing, Computational Fluid Dynamics (CFD) reports, white papers, and material certificates are available for all H2O Rx's static mixers to ensure that you are confident in each mixer for your application.

H2O Rx is the exclusive Australian licensee and distributor of the Westfall Manufacturing range of static mixers manufactured in both Australia and USA.

Types of Static Mixers

There are seven varieties of static mixer in the range. These are:
