Operating principle
Microbubble air separation
The air and dirt separator uses
the combined action of several
physical principles. The active
part is the internal element (1)
and consists of a glass-
reinforced nylon mesh for
th e brass DISCALDIRTMAG
®
,
or for the steel DISCALDIRTMAG
®
an assembly of concentric metal
mesh (stainless steel) surfaces.
These elements create the
whirling movement required to
facilitate the release of micro-
bubbles and their adhesion to
these surfaces.
The bubbles, fusing with each other, increase in volume until the hydrostatic
thrust is such as to overcome the adhesion force to the structure. They
rise towards the top of the unit from which they are released through a
float-operated automatic air vent valve.

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 5461 brass and steel 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 DISCALDIRTMAG
®
NA546_M series (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.

Microparticle dirt separation
The dirt separating action performed by the same internal element (1) offers
little resistance to the flowing medium while ensuring dirt separation. The
particles collide with the concentric diamond pattern mesh surfaces and
then settle to the bottom in the dirt collection chamber (2), and not by filtra-
tion unlike mesh stainers; which, over time, get progressively clogged. By
contrast, the DISCALDIRT
®
's low-velocity zone dirt separator function
efficiently removes the particles to as small as 5μm (0.2 mil) with very low
head loss. The dirt can then be removed through the bottom drain port (3).
