"NEW" Nex Flow Air Edger Flat Jet Air
Nozzle, provides a powerful force while reducing compressed
air use for a variety of blow off applications. The unit is
2" wide and the gap is maintained by a shim. Changing or
stacking various shim sizes allows you to set the force that
you need for any particular application - from a light blow
off to a powerful blow off force.
The Air Edger Flat Jet Air Nozzles are easy
to mount and maintain, reducing both compressed air consumption
and noise levels.
The Air Edger Flat Jet Air Nozzles work
by producing a laminar flow of air along its 2" length
using the "Coanda" effect which entrains a large volume
of air from the surrounding area along with a small amount of
compressed air from the Air Edger Flat Jet Air Nozzle
itself to produce an amplified output flow. Made of cast zinc
aluminum it is a rugged unit applicable for many applications.
Units may be placed side by side to provide an efficient and
strong blowing force over wide lengths.
Compressed air enters the flat jet at the rear
port at (A). Air is entrained at point (B) and (D) by the compressed
air stream that leaves the flat jet from a small gap at the
end. The entrained air follows the profile that directs the
airflow in a perfect straight line to create a uniform sheet
of air along the 2" length of the Air Edger Flat
Jet Nozzle. The amplified air stream maximizes velocity and
force to produce a well-defined sharp edge laminar flow with
minimal wind shear for reduced energy use in blow off and cooling.
Two screws at (C) allow you to vary the gap with a variety of
sizes of shims (.004", .008" or .020"). One or
two shims may be used.

Air Edger Flat Jet Air Nozzles
Model 47011 Air Edger Flat Jet is an extremely
efficient flat jet air nozzle designed to provide a powerful
stream of high velocity laminar flow and high force for blow
off and cooling where air knives may not be enough.
When bench tested against several other flat jets, even those
with special designed holes or shims, the Air Edger Flat
Jet outperformed them all despite whatever claims others may
make. Air consumption and noise levels are minimized with its
special design and configuration.
The Nex Flow Air Edger Flat Jet is
available with various size "gaps" all set by a flat
shim. Three standard shim sizes are available - .004" (.10
mm), .008" (.2mm) and .020" (.51 mm). One, two or
more shims can be "stacked" for a larger gap and greater
47011-4 - Air Edger Flat Jet with .004"
47011-8 - Air Edger Flat Jet with .008" gap setting
47011-12 - Air Edger Flat Jet with .012" gap setting
47011-16 - Air Edger Flat Jet with .016" gap setting
47011-20 - Air Edger Flat Jet with .020" gap setting
47011-24 - Air Edger Flat Jet with .024" gap setting
47011-28 - Air Edger Flat Jet with .028" gap setting
If you are not sure of which level of power you
need, we recommend a Model 47211S Shim Set consisting of 2 -
.004" shims, 2 - .008" shims and 1 - .020" shim
and any two shims (or more) can be stacked to set the gap best
suited to your application.
Air Consumption And Force
(SLPM) at 80 PSIG
- Measured at entrance to jet
in ounces (grams) at 12`from target
It is not always clear how tests and measurements
are made by competitors and therefore validating claims can
be difficult since such values depend on how tests are done.
Therefore we measured a competitive unit under the same conditions
as we measured our units. The flat jet of the competitor is
of a similar type except that they are using a saw tooth shim
design and different internal dimensions. We obtained the following
readings when measured using the same parameters as for Nex
22 SCFM - 22 oz force 25.1 SCFM - 15 oz force
The force/SCFM is a ratio of .54
One measure of efficiency is the ratio of Force/Air
Consumption. The higher the ratio the better the efficiency.
If we compare to that of the Nex Flow Model 47011-4
the ratio is 12/20.5 = .58
And for the Model 47011-8 the ratio is 21/31.3 = .67
In both cases the efficiency of the Nex Flow units
are higher in the comparative tests done. Under the same conditions.
