In heating and air conditioning control systems, the circulation of water containing impurities may result in rapid wear and damage to components such as pumps and control valves. It also causes blockages in heat exchangers, heating elements and pipes, resulting in lower thermal efficiency within the system. The dirt separator removes these dirt particles, collecting them in a large collection chamber from which they can be flushed even while the system is in operation. This device is capable of efficiently removing even the smallest particles, with very low head loss. The DIRTMAG® magnetic dirt separator removes both ferrous and nonferrous impurities continuously, featuring powerful removable magnets that remove up to 100% of the ferrous impurities, including magnetite, that can form in a hydronic system. The DIRTMAG® has 2 1/2 times the removal performance of a standard dirt separator. Insulation shells are available separately for brass models.
  • 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
