The DISCALDIRT
®
air and dirt separator uses a coalescing element that
consists of an assembly of concentric diamond pattern mesh surfaces.
This element creates 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 overcomes
the adhesion force to the structure. They rise towards the top of the unit from
which they are released through a fl oat-operated automatic air release valve.
The dirt separating action performed by the dirt separator is based on using
the internal element with concentric diamond pattern mesh surfaces instead
of an ordinary fi lter. The element offers little resistance to the medium fl ow
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 fi ltration; which, over time, gets progressively clogged.
By contrast, the DISCALDIRT
®
’s low-velocity-zone dirt separator function
effi ciently removes the particles to as small as 5μm (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 that the collected
dirt particles are not affected by the swirling fl ow through the mesh element.
The dirt can then be removed through the bottom drain port.
The fl uid velocity at connections for DISCALDIRT
®
546 and NA546 series
air and dirt separators is recommended to not exceed 10.0 f/s (feet per
second). Above this speed, heavy internal turbulence and noise can occur
and air and dirt separation effi ciency begins to fall signifi cantly. Optimal air
and dirt separation performance occurs at fl uid velocities of 4.0 f/s or less.
See the fl ow capacity chart above.
