Description, Areas of application and Benefits
Linear diffuser SAL 35
The SAL diffuser has linear slots with
35mm profiles. It is composed of
extruded aluminum surfaces with ABS
eccentric drums which slide inside and
are mounted on the plenum.
The SAL 35 is available with one or
multiple slots depending on the application and the required amount of air.
The elements can be mounted one after
another to create a diffusion wave.
Areas of application
- Rest areas with average ceiling
heights.
Benefits
- Adjustable without reducing the
speed of the exiting air flow thanks to
the section of variable drums.
- Areas with levels of elevated and high
- Influence (e.g. extension) on the
speed air movement.

- Situations where the diffuser must
adapt to the contours and colors of
the space.
- Influence on the method of induction
(diffuse mode).
- Systems with variable flow.
- Adjustment of the penetration of the
air jet.
- Offices, conference rooms, computer
rooms, white rooms, shopping malls,
cinemas, theatres etc.
- Optional suppression of the Coanda

- Change of the direction of the jet.
- Reproductive diffusion setting.
- Factory default setting.
- Adjustment of the diffuser still

The SAL linear diffuser slots are
composed of extruded aluminum (1)
with additional wide or narrow profiles
(2), the eccentric drums (3), which can
rotate 360° and a plenum (4).
The eccentric drums (3) offer an acoustic level and optimal aerodynamics,
and possess on their axis multiple air
guiding planes (5), a display and
adjustment dial (6) on which are alphanumeric characters, allowing the user
to define and reproduce the drum
settings. The profiles, with a powder
coated paint are attached to the
plenum with the aid of rivets for applications in a suspended ceiling and by
central screws for the gypsum ceilings.

1.1.3
SAL 35
Mode of operation
The eccentric drums form, with the aid
of the aluminum air guiding slots a flow
of optimal air.
The design of approach to the drums
causes a drop in pressure as the air
enters. As the air leaves the slot it is
stable and generates a low level of
acoustic power. The flow maintains a
powerful induction of ambient air.
The positioning of the eccentric drums
allows an adjustment of the direction
of the air jet, with or without reduction
in the exit area.
To maintain a dense airflow and maintain the direction of the air flow
perpendicular to the axis of the drums,
the drums have small plates to guide
the air.
Mode of operation
Adjustment of the air jet direction
Thanks to the shape of the eccentric
drums and adjustment dial with alphanumeric characters, the direction of the
air jet at the outlet of the diffuser can be
directed changed up to 180°. For each
direction there are two (2) drums
positions (“reduced” or “not reduced”
positions) as illustrated in the diagram
above. The direction of the jet is indicated on the diagram if the diffusers are
freely suspended. For a ceiling installation, a horizontal airflow is generated
by the Coanda effect with the drums in
positions EF, F6, 1A, AB and 21, 32, 54
and 65. The length of the drums can
each be adjusted up to 100mm.
As a result, the combinations of airflow
are almost infinite. During manufacture, the drums are normally set
alternately in position 21 and 65 (diffusion mode). This setting produces
airflow with a strong induction which
can be used even in areas with high
cooling needs and mixed air rates.

Outlet airflow
The diagram below shows the ratio
between the airflow exiting the diffuser
and the drum position; the pressure of
the system remains unchanged. On the
other hand, through an increase of
pressure upstream, the speed of exiting
air can be noticeably increased while
maintaining the same airflow even with
the drum in the “reduced” setting.

Controlling the direction of the air jet
The setting produces airflow with
strong induction which can be adjusted
to the cooling or heating needs of the
room in areas with high airflow.
When all of the drum of the first slot are
adjusted to 2 1 and in the second slot
are adjusted to 6 5, the adjustment
produces a flow in two directions
(divergent).
The diagrams below illustrate the
different relationships between the
position of the eccentric drums and the
direction of the air jet at the outlet of
the drum.

As a result, the combinations of airflow
are almost infinite. For the diffusion
mode, the drums must be set alternately to the configuration illustrated in
the diagram in positions 2 1 and 6 5.
It doesn’t matter if multiple slots are
mounted parallel to one another; any
airflow or direction of air can be achieved through different drum combinations.
max. 4 m (13 ft)
Due to the zone of low air pressure and
the level of the eccentric drums, the
direction of the air flow can be altered
by up to 180°.
During assembly the NAD label
must always be placed on the same
side as the collar of the plenum.

2. From the sizing diagram, a wall

after they meet y=3m – 1.8m = 1.2m, 3
we can find the maximum air speed
in the occupied zone of :

can determine the critical distance
Xcrit = 8.5m 6
4. The acoustic power diagram and
airflow by metre of slot of 85m3/h/m
we read the acoustic power diagram
LWA = 28 dB(a). 7
From the values shown in the table
we calculate the level of power
generated: LWA = LWA diagram + I =
28+4.7+7.8 = 40.5 dB(A)
40.5 dB(A) - 10 dB(A)= 30.5 dB(A)

Solution:
1. For a total air flow of 1535m3/h and 4
SAL35 diffusers, we find:
1535 X 4 = 384 m3/h by diffuser.
We divide by the number of slots:
384 m³/h ÷ 3 = 128 m³/h.
Each slot of 1500mm = 1.5m in
length, we divide by 1.5 to find the air

Specifications
1 - Description and physical characteristics
2 - Performance
1.1 The NAD Klima SAL 35 ceiling air diffuser is composed of
extruded aluminum blades with one, two or multiple slot
combinations. A width of 35mm and with plastic (ABS)
eccentric drums in either matte black or white.
2.1 The SAL 35 diffuser assures a strong rate of induction
even in highly variable areas in order to maintain an
acceptable temperature differential in the air jet. That is
to say, the difference between the designated temperature and the temperature of the air projected by the
diffuser into the occupied zone.
1.2 The 100mm long NAD Klima eccentric drums are individually adjustable with an alphanumeric codification and
can be rotated through 360°. Accordingly the diffuser
remains fully adjustable throughout the range of diffusion
(in height and through 180°).
1.3 The diffuser is supplied with a wide or narrow profile.
2.2 The performance of the SAL 35 diffuser is guaranteed by
a software simulation which indicates the loss of
pressure and the acoustic power generated. It also
provides a cross-sectional view of the critical trajectory
of the air and the nominal speed in the occupied zone in
cooling mode, in heating mode and isothermal mode at
1.8m from the ground or at the request of the engineer.
3 - Adjustment
3.1 The diffuser includes a plenum provided by the manufacturer. The plenum is made from 24 gauge galvanised
steel and comprises suspension points at the four
corners. The inlet collar can be centred on the side and
adapted to the air flow. The interior joints of the plenum
are sealed with silicon.
3.2 The SAL 35 diffuser includes a perforated airflow
stabilizing (equalizing) frontal plate.
4 -Balancing
4.1 The balancing must be executed by a ventilation
balancing technician with a recognised professional
certification.
4.2 The technician must take into account the factor of
correction for the volume of air using a balometer (factor
FCB).
5 - Certification
5.1 The linear diffuser SAL 35 meet the standard of ASTME
162 "Surface Flammability of Materials Using a Radiant
Heat Energy Source"
6. Required quality : NAD Klima SAL 35 model.
