Type XARTO swirl diffusers meet
the most demanding requirements
of technical function, comfort, and design.
Diffuser faces come in classic, modern
and flamboyant styles and can be creatively
integrated with all types of ceilings. They form
in fact an attractive design element for building
owners and architects.
The combination of swirl unit, newly developed
equalising element and innovative plenum box
provides high volume flow rates, a low sound
power level and low differential pressure.
The air control blades of the swirl unit have
three-dimensionally profiled contours to create an
efficient swirl. As a consequence, the air velocities
and temperature differences in the occupied zone
are very low, and the level of comfort is excellent.
A spigot with double lip seal provides
a low-leakage connection of the plenum box
to the ducting, and a damper blade for volume
flow rate balancing simplifies commissioning.

Function
XARTO
Functional description
Ceiling swirl diffusers in air conditioning systems
create a swirl to supply air to rooms. The resulting
airflow induces high levels of room air, thereby
rapidly reducing the airflow velocity and the
temperature difference between supply air
and room air. Ceiling swirl diffusers allow for
large volume flow rates. The result is a mixed
flow ventilation in comfort zones, with good
overall room ventilation, creating only very
little turbulence in the occupied zone.
Design ceiling swirl diffusers are characterised
by a diffuser face plate with a particular pattern.
The swirl unit required for the swirling
air discharge is situated inside the plenum box
and hence not visible from the room.
Type XARTO ceiling swirl diffusers have fixed
blades. Air discharge is horizontal omni
directional. The supply air to room air temperature
difference may range from –12 to +10 K.
A damper blade simplifies volume flow rate
balancing for commissioning.
To give rooms an aesthetic, uniform look,
Type XARTO diffusers may also be used
for extract air.

Quick sizing
XARTO-Q*-Z
(supply air)
Quick sizing tables
provide a good overview
of the volume flow rates
and corresponding sound
power levels and
differential pressures.
The minimum volume flow
rates apply to a supply air
to room air temperature
difference of –6 K.
The maximum volume
flow rates apply to a
sound power level of
approx. 50 dB (A) with
damper blade position 0°.
Exact values for all
parameters can be
determined with our
Easy Product Finder
design programme.

Design ceiling swirl diffusers with square
or circular diffuser face, for comfort zones with
particularly demanding requirements of aesthetics
and design. Supply air and extract air variants.
Excellent aerodynamic and acoustic function
due to swirl unit with optimised aerofoil contours,
for horizontal swirling air discharge, creating high
levels of induction. For installation into all types
of suspended ceilings.
Ready-to-install component which consists of the
casing, diffuser face, swirl unit, spigot, and a cross
bar to which the diffuser face is fixed.
The diffuser face is fixed to the cross bar
with a central screw.
Spigot suitable for ducts to EN 1506 or EN 13180.
Sound power level of the air-regenerated noise
measured according to EN ISO 5135.
Special characteristics
– For the most demanding requirements
of technical function, comfort, and design
– Diffuser face in many different designs
– For all types of ceiling systems,
and with an extended border also suitable
for freely suspended installation
– Horizontal duct connection

Sizing with the help
of this catalogue
This catalogue provides convenient quick sizing
tables for ceiling diffusers.
The tables give supply air volume flow rates
for all nominal sizes. The maximum volume flow
rates are for an open damper blade. A smaller
opening of the damper blade results in higher
sound power levels and a higher total differential
pressure. The tables show values for damper
blade positions 45° and 90°.
Sizing data for other volume flow rates
and damper blade positions can be
determined quickly and precisely using
the Easy Product Finder design programme.
Sizing example
Given data
 = 300 l/s (1280 m3/h)

Four-way air discharge

The Easy Product Finder

Volume flow rate balancing
When several diffusers are connected to just
one volume flow controller, it may be necessary
to balance the volume flow rates.
– AIRNAMIC, XARTO, FLEXTRO:
The diffuser face can be removed to access
the damper blade; the damper blade can
then be set in 15° intervals between 0 and 90°
– Ceiling diffusers with universal plenum box
and damper blade (variant -M):
The diffuser face can be removed to access
the damper blade; the damper blade can
then be set to any position between 0 and 90°
– Ceiling diffusers with universal plenum box,
damper blade and pressure tap (variant -MN):
The diffuser face need not be removed since
the damper blade can be set with two cords
(white and green).

Volume flow rate measurement
Ceiling diffusers with universal plenum box,
damper blade and pressure tap (variant -MN)
allow for volume flow rate balancing even
with the diffuser face in place.

– Connect the measuring tube
to the digital manometer
– Read the effective pressure
– Read the volume flow rate off
the characteristic or calculate it
– If necessary, adjust the damper
blade position with the cords
A characteristic is included
with each AK-Uni plenum box.
