  • Features and More


  • Low velocity zone and large dirt capture area - Pipe velocity slows by a factor of 9 as fluid enters chamber, unlike strainers which clog and cause increased pressure drop, debris is removed from the flow path and captured in lower bowl area, simplifying and reducing frequency of cleaning
  • Robust mesh construction - Unique dirt separation mesh uses deflection and gravity to separate dirt particles as small as 5 microns from flow stream, concentric pattern design has low flow resistance resulting in 85% less pressure drop compared to same size y-strainer
  • Powerful neodymium rare-earth magnets - Magnetic field attracts and captures microscopic ferrous oxide impurities, removes 2-1/2 times the ferrous oxide compared to other dirt separators
  • Clip-on magnetic ring and convenient purge valve - Opening purge valve and removing magnetic ring releases captured magnetic impurities and purges all dirt without shutting down the system
  • Top access port - 1/2 in NPT top provides convenient chemical additive dosing port
  • Corrosion resistant - All components highly resistant to hydronic chemical additives or unstable pH fluid
