Microparticle dirt separation
The DISCALDIRT
®
 and DISCALDIRTMAG
®
 dirt removing element separates and collects any 
impurities present in thesystem.
Impurities in the fluid upon striking the surfaces of the DISCALDIRT
®
 and DISCALDIRTMAG
®
’s 
internal element (1), get separated and drop to the bottom of the body in the dirt collection 
chamber (2) where they collect.
In addition, the large internal volume slows down the velocity of the fluid thus helping, by 
gravity, to separate the particles it contains.
The collected impurities are discharged, by opening the drain valve (3), even with the system 
operating.
Ferrous impurities separation
Non-ferrous and ferrous impurities, including magnetite, in 
hydronic systems can deposit onto heat exchanger surfaces 
and accumulate in pump cavities causing reduced thermal 
efficiency and premature wear. The small and often microscopic 
magnetic particles, called magnetite, form when iron or steel corrodes. 
Highly abrasive, the extremely fine particles are difficult to remove 
by traditional means. DISCALDIRTMAG
®
 separators offer highly 
efficient separation of typical dirt as well as magnetite. The versatile 
DISCALDIRTMAG
® 
magnetic air and dirt separator removes 
both ferrous and non-ferrous impurities continuously. In addition 
to removing typical dirt particles with an internal element in a 
low-velocity-zone chamber, the DISCALDIRTMAG
®
 features 
a powerful removable magnet below the flow line for fast and 
effective capture of ferrous impurities.The magnet removes up to 100% of the ferrous impurities, 
including magnetite, that can form in a hydronic system.
For the brass and steel 5461 series DISCALDIRTMAG
®
(A, B, D), the ferrous impurities are captured 
by a strong neodymium rare-earth magnetic field created by a powerful removable magnet around 
the body below the flow line. 
For the steel 546 and NA546 series DISCALDIRTMAG
®
(C), the ferrous impurities are captured 
by a concentrated magnetic field created by a stack of neodymium rare-earth magnets positioned 
inside a brass dry-well below the flow stream.
