In the DISCALDIRTMAG
TM
air and dirt separator with
magnets ferrous impurities are
captured by a concentrated
magnetic field created by a
stack of neodymium rare-earth
magnets positioned inside a
brass dry-well which is below
the flow stream. Non-magnetic
dirt particles are separated by
colliding with an internal element
in the flow stream and settling to
the bottom. The deep collection
chamber keeps the dirt from re-
entering the flow stream. The
dirt and ferrous impurities are
flushed out while the system
is operating, by removing the
magnets and opening the purge
valve.

Low head losses and high performance are maintained over time. The dirt
separating action performed by the DISCALDIRT
®
air and dirt separator is
based on using the internal element with concentric diamond pattern mesh
surfaces instead of an ordinary filter. The element offers little resistance to
the medium flow while ensuring dirt separation. This occurs due to the
particles colliding with the concentric diamond pattern mesh surfaces
and then settling to the bottom, and not by filtration; which, over time,
gets progressively clogged. By contrast, the DISCALDIRT
®
low-velocity
zone air and dirt separator efficiently removes the particles to as small
as 5 μm (0.2 mil) with very low head loss. The dirt collection chamber
at the bottom of the DISCALDIRT
®
is at the right distance from the inlet
and outlet connections so that the collected dirt particles are not affected
by the swirling flow through the bottom drain port, even with the system
running, by opening the drain valve with the handle.
