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-rein-
forced nylon mesh for the
brass DISCALDIRT
®
or for
the steel DISCALDIRT
®
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.

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).

The geometrical structure of
DISCALDIRT
®
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.
