Technical description
Design
IBIS duct air diffuser with discs has a diameter that is
compatible with standard duct sizes. IBIS is equipped with
aerodynamically designed discs that have a high induction
capacity. The 160 mm dia. and 200 mm dia. IBIS duct air dif-
fusers are equipped with Swegon’s small discs. The standard
duct diffuser is available in a number of sizes as shown in
Figure 12 as well as in the Dimensions and weights table. There
is an aluminium profiled bracket along the top of the duct. The
bracket runs longitudinally and serves as a flexible mounting
bracket for hanging the duct diffuser from the ceiling.
Materials and finish
The duct air diffuser with discs is made of galvanized
sheet steel and is painted in Swegon’s white standard
colour, RAL 9010. The discs are made of recyclable ABS
plastic. The air diffusers are also available in alternative
standard colours: RAL 7037 dusty grey, RAL 9006 white
aluminium, RAL 9005 jet black, RAL 9007 grey aluminium
and RAL 9003 signal white (NCS 0500).
Customizing
In addition to the size specified, the duct diffusers are available
in alternative sizes, number of discs, etc. For more info, get
in touch with your nearest Swegon representative.
Project planning
The discs are rotatable through 360°. This makes it pos-
sible to achieve an infinite number of horizontal or vertical
air diffusion combinations without altering the airflow,
sound level or pressure drop.
The duct diffusers are well-suited for installation in the
junction of a ceiling with a wall without reducing its
flow capacity. The discs on the back side are then set for
upward air discharge enabling the duct air diffuser to oper-
ate as a air diffuser with one-way air discharge. See Figures
1 and 2 for examples of principle air diffusion patterns.
Normal hanger length is 200 mm. The smallest permit-
ted hanger length is 100 mm which generates slightly
increased throw.
Commissioning
An IBIS C (see under accessories) or a flow measuring damper
installed in the duct system upstream of the duct diffuser is
recommended for commissioning and airflow measurements.
The Methodic errors table and Figure 3 describes require-
ments on straight duct lengths for upstream obstructions.

IBIS B: 45° and 90° bend painted white.*)
IBIS T: T-piece painted white.*)
*) Available for sizes 160-400. For 500 and 630, standard acces-
sories are recommended.

Maintenance
The air diffuser can be cleaned, if necessary, using luke-
warm water with dishwashing detergent added or by
vacuum cleaning using a brush nozzle.

Installation
The duct diffuser is suspended by hangers from the cei-
ling. The air diffusers can be installed as in the following
examples:
Phase A
s While the duct section (1) is lying on the floor, insert a
size M-8 bolt (2) approx. 100 mm from the end on the
longitudinal profiled bracket (3). Do the same in the
other end of the profiled bracket.
s Secure the bolts in the profiled bracket with long nuts
(4). Screw a threaded rod (5) of appropriate length into
each long nut.
s Secure the Z-profiled brackets (6) with bolts to the cei-
ling to serve as mounting brackets for the duct-shaped
air diffusers with discs.
s Hang the duct air diffuser with discs (1) in the Z-profiled brack-
ets (6) and join it together with the connecting supply air duct
(7) using the standard duct joint (8) included in the supply.
s Adjust the duct diffuser using the nuts (9) until the air
diffusers are horizontal and have the correct height
above the floor. Fit the white plastic covering supplied
(15) onto the threaded rod.
Phase B
s Remove the end cover (13) and move it to the outmost
section if more sections are to be installed. Press the
distribution joint supplied (10) in the mounted section
of the duct diffuser (1).
s Insert the guide pin (11) in the free end of the installed
section.
s Repeat phase A to install the next section (12). Now it
is sufficient to use one bolt in the other end when the
second duct diffuser section is to be secured across the
joint to the section that you’ve already installed. Secure
the distribution joint (10) with self-tapping screws in
the sections. Repeat Phase B for last section.
Phase C
s Install the inactive IBIS D duct sections (14) in the same
way as the duct air diffuser sections with discs. Note
the use of supplied joints (8) and distribution joints (10)
included in the supply.
s In all deliveries, the end cover (13) supplied is already
fitted to the first section. The end cover is always moved
to the last section (except when only 1500 mm long
ducts are installed), see Phase B in Figure 4.

Technical data
s Sound level dB(A) applies to rooms with 10 m2equiva-
lent sound absorption area (4 dB room attenuation).
s Throw l0.2 is measured for isothermal air discharge and
applies to installation 200 mm from the ceiling.
s A max. permissible temperature below room temperature
of 8 °C is recommended for standard setting of the discs.
s The recommended highest permissible air velocity in
the duct upstream of the air diffuser is 3-4 m/s.
s For calculating the air stream propagation, air veloci-
ties in the occupied zone, or sound levels in rooms
with other dimensions, we refer to our ProAir Web and

Figure 5. 2-way air discharge with short throw. All the discs are
set for discharging air upward toward the aluminium strip.
Figure 7. 1-way air discharge toward a wall. The uppermost row
of discs on the air diffuser half facing the room should discharge
air downward; the other discs should discharge air upward.
Throws
2-way air discharge, short
The throws for 2-way air discharge, short, are specified on
the following pages in the sizing diagram.
Example:
IBD-315-3500-8 produces a flow of 260 l/s at 30 dB(A). A
throw of 4.3 m is specified.
2-way air discharge, long
To calculate the throw for "2-way air discharge, long"
multiply the throw in the relevant diagram by 1.75.
Example:
IBD-315-3000-8 produces a flow of 260 l/s at 30 dB(A).
A throw of 4.3 m is specified. The throw for 2-way air
discharge will then be: 1.75 x 4.3 m = 7.5 m
1-way air discharge
To calculate the throw for 1-way air discharge, multiply
the throw in the relevant diagram by 2.0.
Example:
IBD-315-3000-8 produces a flow of 260 l/s at 30 dB(A).
A throw of 4.3 m is specified. The throw for 1-way air
discharge will then be: 2.0 x 4.3 m = 8.6 m
For the calculation of throws for air that is below or above
room temperature, refer to our ProAir air diffuser selec-
tion program which is available at www.swegon.com.

row of discs on both sides of the aluminium strip should be set
for downward air discharge.
