Presentation and b ene�ts
Areas of application- Rooms with average ceiling heights- Situations where the di�user must adapt to the contours
and colours of the room- O�ces with partitioned workspaces- Clean rooms- Call centres- Closed o�ces- Computer (server) rooms- Meeting rooms- Multi-purpose rooms- Systems with constant or variable air�ow rates- Entrance halls (vertical air streams)- Fenestrated walls- Theaters
Bene�ts- In�uence on the method of induction (di�use
mode), extension of jets (divergent mode) and a very long vertical stream in heating mode (diver-gent nozzle rollers)
- Rapid reduction of �ow speed and temperature variations caused by high induction
- Low acoustic power for high air�ow rates- Stable laminar air�ow and a variety of air�ow
directions available - Eccentric rollers allowing 180° air�ow adjustment- Possibility of adjusting air�ows, even after installa-
tion- Possibility of reducing total air�ow rate as much as
25% in VAV- Approximately 3 times more induction than a
conventional linear di�user- Approximately 3 times less temperature variation in
occupied area than a traditionnal di�user- Possibility of eliminating external heating sources
due to the di�user‘s heating abilities- Adaptable to systems requiring constant or variable
air�ows- Areas with high air movement and low air velocity in
the occupied zone
The SAL 35 di�user is composed of extruded aluminum surfaces with eccentric rollers, which slide inside and are mounted on the plenum, as well as linear slots with 35 mm pro�les. Each di�user is supplied with a stabilising chamber, allowing for a uniform and silent air�ow.
The SAL 35 is available with one or multiple slots, depending on the application and required amount of air. The di�users can be installed in series, one behind the other, creating a continuous e�ect to the ceiling.
The SAL enables optimal con�guration of the ventilation system to meet a room’s require-ments. Due to the eccentric rollers, a variety of airstream con�gurations can be achieved, even after the unit has been installed.
The SAL 35’s technology provides high speed discharge of air with low acoustic power.
The laminar �ow, the stability and the high induction generated from the very start of the outlet vent make the SAL the linear di�user of
choice for high air �ow rates and variable air volumes.

Con�guration and mo de of op eration

Con�guration
The SAL linear di�user slots are composed of extruded aluminum (1) with additional wide or narrow �nishing pro�les (2), eccentric rollers (3), which can rotate on 360 degrees and a plenum (4).
The 100 mm long eccentric rollers (3) o�er a low acoustic level and optimal aerodynamics. They possess on their axis multiple air guiding planes (5), a display and adjustment dial (6) on which are alphanumeric characters, allowing the user to de�ne and reproduce the roller settings.
The nozzle roller is the same dimension as the eccentric roller, with a larger e�ective surface. It is designed for application in locations with high ceilings.
The pro�les are attached to the plenum with screws for suspended ceilings and with central screws for gypsum ceilings.
The di�user is powder coated with a polyester TGIC-free paint, providing a smooth, easy-to-clean, chip and fade resistant �nish. The colours are available from the RAL colour chart.
Indexing- range
Mode of operation
The eccentric rollers and nozzle rollers form, combined with aluminum air guiding slots, an optimal air �ow.
A drop in pressure occurs when approching the surface of the rollers. As the air leaves the slot, it is stable and generates a low level of acoustic power. The �ow maintains a powerful induction of ambient air.
The positioning of the eccentric rollers allows an adjustment of the air jet’s direction, with or without reduction in the exit area.
Rollers have small plates to guide the air, which support a dense air�ow and maintain the air �ow direction perpen-dicular to the rollers’ axis.
Adjustment of the air jet direction
Thanks to the shape of eccentric rollers and adjustment dial with alphanumer-ic characters, the direction of the air jet at the di�user’s outlet can vary up to 180°. For each direction, there are two (2) roller positions (“reduced” or “not reduced”), as illustrated in �gure B.
For a ceiling installation, a horizontal air�ow is generated by the Coanda e�ect, with the rollers in positions EF, F6, 1A, AB and 21, 32, 54 and 65. The length of the rollers is adjustable up to 100 mm.
As a result, the combinations of air�ow are almost in�nite. During manufactur-ing, rollers are normally set alternately in position 21 and 65 (di�usion mode). This setting produces a strong induction �ow, which is e�ective even in high cooling needs and mixed air rates.
The nozzle roller can only be set in open and closed positions.

Controlling the direction of air�ow
The diagrams below illustrate the di�erent relationships between the position of the eccentric rollers and the air jet’s direction at the roller’s outlet.
Notes : The adjustable side of the roller must be to the left of the collar. During assembly, the NAD label is placed on the same side as the collar of the plenum.
When the air inlet is on the top or a wall installation, follow the directions on the workshop design.

5. NC value and acoustic power LWA
4. Loss of pressure ∆P t
Solution:3/h and 4
1535 x 4 = 384 m 3
We divide by the number of slots: 384 m3/h ÷ 3 = 128 m3/h. Each slot of 1500 mm = 1.5 m in
128 m3/h ÷1.5 = 85 m3/h/m 2. From the sizing diagram, a wall
distance x = 2 m and a trajectory after they meet y = 3 m – 1.8 m = 1.2 m,
in the occupied zone of: Vmax = 0.25 m/s
3. For the cooling mode of -15°C, we can determine the critical distance Xcrit = 8.5 m
5. The NC Value and acoustic power for air�ow per meter of slot of 85 m3/h/m
are: LWA diagram = 28 dB(A)
From the values shown in the table we calculate: NC diagram = 13 +7 = 22 LWA = LWA diagram + I = 28 + 4.7 + 7.8 = 40.5 dB(A)
40.5 dB(A) - 10 dB(A) = 30.5 dB(A)
slot we read: ∆Pt = 13 Pa 4. For an air�ow by meter of 85 m3/h/m

1. Description and physical characteristics
1.1 The high induction linear di�user shall be made of extruded aluminum pro�les.
1.2 The 100 mm long eccentric rollers shall have an alphanumeric identi�cation, which will allows an adjustment of the air �ow pattern over 180 degrees.
1.3 The di�user shall be adjustable to �t regular North American suspended ceilings, classic gypsum ceilings or wall installations.
1.4 The di�user shall be supplied with a wide or narrow pro�le.
1.5 The di�user shall be powder coated with a polyester TGIC-free paint, providing a smooth, easy-to-clean, chip and fade resistant �nish. The architect or client shall choose a standard colour from the RAL colour chart.
2. Performance
2.1 The performance shall be guaranteed by using performance curves or simulation software for critical areas. These curves shall indicate the pressure drop, acoustic power generated as well as showing a cross-sectional view, illustrating the critical air�ow path in cooling, isothermal and heating modes.
2.2. Parameters of guaranteed comfort 2.2.1 The performance statistics of the di�user shall re�ect a maximum air speed of 0.15 m/s (30 ft/m), in occu-pied zone at 1.3 m (4 ft) from the �oor. The performance guarantee shall be demonstrated with performance curves showing the path of the air stream.
2.2.2 The di�user shall ensure a maximum tempera-ture di�erence of -1°C between the air jet and the occupied area 4 ft (1.3 m) above the �oor. To achieve this, the ratio of temperature di�erential shall perform at a minimum of ΔTxy / ΔT0 ≤ 0.1 (for an initial di�erential of ∆T0 = -10˚C).
2.2.3. In cooling mode, the di�user shall guarantee, in variable volume (VAV), a critical distance (Xcrit) of at least the value is indicated in the following table:
3. Plenum
3.1 The di�user shall include a plenum provided by the manufacturer. The plenum shall be made from 24 gauge galvanised steel and comprise suspension points at the four corners. The inlet collar shall be centered on the side and adapted to the air �ow. The interior joints of the plenum shall be assembled by clinching and sealed with silicon.
3.2 When required, the plenum shall be supplied with a damper adjustable through the �nished side of the front plate, in order to adjust the air volume. This damper shall be available in two options:
3.2.1 Radial damper: Key with circular pivoting blades on a �exible metallic cable, which is adjustable through the front plate of the di�user, allowing for air �ow adjustment from 0% to 100%. 3.2.2 Spring key: Pivotally perforated plate at the inlet, adjustable with a spring mechanism through the front of the di�user.
4 - Balancing
4.1 The balancing shall be executed by a ventilation balancing technician with a recognised professional certi�ca-tion.
4.2 The technician shall take into account the volume correction factor using a balometer (FCB factor).
5 - Required quality: NAD Klima, SAL 35 model.
