COLIBRI Ceiling
Technical description
Design
The square supply air diffuser consists of a diffuser back-
ing box and a diffuser face. The diffuser face is equipped
with aerodynamically shaped, adjustable discs. The dif-
fuser face is hung on hinges on one side and secured by
springs on the opposite side. This Quick Access fastening
system makes it simpler and quicker to open and close the
diffuser face for installation, commissioning and cleaning.
air diffuser is also available in a low version for installation
in a ceiling void where low installation height is required.
The air diffuser is then supplied without sleeve coupling.
Materials and surface treatment
The backing box and diffuser face are made of sheet steel.
The connection branch is made of galvanized sheet steel. The
interior and exterior of the air diffuser is painted in our white
standard colour, RAL 9010. The air diffuser is also available in
alternative standard colours: Dusty grey RAL 7037, white alu-
minium RAL 9006, jet black RAL 9005, grey aluminium RAL
9007 and signal white RAL 9003 (NCS 0500).
The discs are made of ABS plastic.
Accessories
Commissioning box:
ALS. Made of galvanized sheet steel. Contains removable
commissioning damper, fixed measurement tappings and
sound absorbing material with reinforced surface layer, to
Fire Resistance Class B-s1,d0 according to EN ISO 11925-2.
The commissioning box is also available in a low version for
installation in a ceiling void where low installation height
is required. The air diffuser is then supplied without sleeve
coupling. The commissioning box is available with 1 or 2
changes in dimension between the inlet and outlet.
Frame:
SAR K. For aesthetic installation of a lowered diffuser.
Adapter:
ADAPTER, for adaptation to various variants and makes
of systemized false ceilings: Ecophon, Gyproc, Dampa etc.
Also used for adaptation to optional sizes of lay-in ceil-
ings, for instance 625 x 625 or 675 x 675. Specification in
separate product sheet for ADAPTER.
Planning
The COLIBRI Ceiling is available with square dimensions of
595 x 595 mm in all connection sizes. This makes COLIBRI
Ceiling very easy to install in 600 x 600 suspended ceiling
modules. Position these directly down in the T-bar frame-
work, and then secure them to the duct system or to the
commissioning box. COLIBRI Ceiling is also available in a
low version for installation in ceiling void where low
installation height is required. See Figure 2.
Installation
To dismantle the face (see Figure 1) prior to installing
the air diffuser, insert a thin object, such as a Quick
Access card or similar card, between the air diffuser face
and backing box to release the springs. Then slide the

card from the centre outward toward the corners. The
inlet spigot of the diffuser backing box can be secured to
the connecting ducting by means of self-tapping screws
or a blind rivets. For flush-mounting in fixed ceiling con-
structions, secure the diffuser by means of screws into
place in the framework through either the sides or top of
the diffuser backing box. The face and backing box in the
version for low installation height must be centred and
jointed together using the locking strip supplied. Secure
the air diffuser in the correct position by means of self-
tapping screws to the underside of commissioning box.
For mounting in modular suspended ceilings, it is advis-
able to select air diffusers with outer dimensions of
595 x 595 mm. Position these directly down in the T-bar
framework, and then secure them to the duct system or
to the commissioning box. If an ALS commissioning box
is used, it must be secured to the building structure by
means of hangers or mounting brackets.
The distance between the air diffuser and the commis-
sioning box can be increased by as much as 500 mm with
an ordinary circular duct without having to lengthen the
measuring tubes and damper adjustment cords.
See Figure 2.
Commissioning
Commissioning must be carried out with the diffuser face
mounted. Pull out the measuring tubes and damper
adjustment cords through the diffuser face discs. Connect
a manometer to the measuring tubes. The desired com-
missioning pressure can be computed by applying the
rated coefficient of performance of the air diffuser. Set
the damper blade in the correct position and tie the
damper adjustment cords in a commissioning knot to
indicate the damper position.
The rated coefficient of performance (K-factor) is specified on
the identification label of the product and the relevant commis-
sioning instructions are also available at www.swegon.com.
Maintenance
The air diffuser can be cleaned, if necessary, using lukewarm
water with dishwashing detergent added. The duct system
can be accessed after opening the diffuser face. If an ALS
commissioning box is used, pull the distributor plate aside and
then grip and twist the damper unit from of its mounting.
