Compact Model 2800 Static Mixer
Complete mixing – short lay length
Westfall’s high shear static wafer style mixer has a short lay length, which allows simple drop-in installation in pipelines from 1/2′′ to 120′′. Its computer-designed orifice with bent tabs generates complete mixing through a combination of alternate vortex shedding and intense shear zone turbulence. High shear mixing is very effective for removal of salt from oil or oil from water. Where space is limited, this affordable static mixer is ideal for municipal and regional infrastructure upgrades.
Up to six additives can be injected simultaneously or in specifically timed stages. Choose from a wide range of injection ports and quills, and 3 aperture sizes: .7 BETA, .8 BETA and .9 BETA.
The 2800 static mixer resists fouling and requires little to no maintenance for many decades of trouble-free service.
The 2800 Static Mixer can be NSF certified in 316 Stainless Steel, PVC, CPVC or Hastelloy C-276®
