Product Overview

Geometric structure and large dirt collection chamber
The geometrical structure of DIRTMAG
®
reduces the flow media velocity
to help separate dirt particles. The dirt collection chamber has the
following features:
• It is located at the bottom of the device at such a distance from the
connections that the collected dirt is not affected by the swirl of the
flow through the mesh element.
• It has enough capacity to increase the amount of dirt stored and
therefore decreases the frequency of emptying it compared to filters
that need to be cleaned frequently.
• It is easily inspected, by unscrewing it from the dirt separator body for
servicing the internal mesh element when large debris are trapped in it.
Separation of ferrous impurities
This series of dirt separators, complete
with a magnet, offer greater efficiency in
the separation and collection of ferrous
impurities, including magnetite. The impurities
are trapped inside the dirt separator body
by a strong magnetic field created by a
removable rare-earth magnet around the
body below the flow line for fast and effective
capture of ferrous impurities.
The magnetic ring can also be removed
from the body for discharge of impurities
while the system is still running. Since the
magnetic ring is positioned outside the
dirt separator body and causes no added
system pressure drop, high performance
hydraulic characteristics are maintained.
Ferrous impurities, including magnetite, form
in hydronic systems when iron or steel corrodes. The abrasive, extremely
fine sediment is difficult to remove and can deposit onto heat exchange
surfaces and accumulate in pump cavities causing reduced efficiency
and premature wear. The DIRTMAG
®
accomplishes 2 1/2 times the
ferrous impurities removal performance of standard dirt separators,
delivering up to 100% elimination efficiency. Captured impurities are
easily flushed by unclamping the ring and purging - even with the
system still operating.
Adjusting the body to horizontal and vertical pipes
Featuring a special coupling
between the locking nut and the
tee pipe fitting, the DIRTMAG
®
dirt separator can be adjusted (1)
for installation to either horizontal
(2) and vertical (3) pipes, while
maintaining the same operating
performance.
