• Westfall Static Mixers: Highly efficient with Low Headloss

Model 5000 Open Channel Static Mixer

Low Headloss Static Mixer Reduces Flooding and Fouling

The patented Model 5000 Open Channel Mixer is a simple drop-in static mixer that is affordable, durable, resists ragging and flooding, requires no outside power source and is easy to retrofit.

This static mixer contains no moving parts, is economical to manufacture and operate, is lightweight, and easy to install. It can be used in remote locations, all while achieving the same or better mixing outcomes as propeller and rotating blade mixers.

Vane Placement is Key

The Model 5000 Mixer offers a choice of one, two or three angled, hydro-dynamic mixing vanes anchored in a sequence to the bottom of the mixer. Each vane is angled at 45 degrees, one of the reasons this mixer resists plugging and fouling. The vanes have a T-shaped downstream edge and the mixing cap is triangular. This creates counter-rotating vortices for effective mixing. The upstream nozzle delivers additives to the zone of turbulence. A wide range of additives is possible.

Rather than being caught in the mixer, debris is lifted up and washed along with the flow to be removed later by rake screens at the water treatment plant.

Choose the configuration that fits the application’s requirements for mixing vs. headloss. Available in appropriate materials determined by the installation specifications.

Easy Installation

The mixer bolts to the bottom of the channel and fits any open channel up to 20 ft. wide and 20 ft. deep. (6.096 meters wide by 6.096 meters deep)
