PMW-ADPerforated Multistream Di�user
The high momentum air streams discharged by the
nozzle plates remain substantially discrete (figure 3)
and a r e h i g h l y i n duc t i v e, i n duc i ng bo t h l ow
momentum ai r d ischarged by the fixed nozz les
around the per imeter of the d i f fuser, and large
quantities of room air.
Rap i d t empe r a t u r e equa l i s a t i o n and i n t en se
discharge velocity decay occur, bringing about low
ve loc i t y a i r mo t i on w i t h un i f o rm tempera tu re
distribution throughout the occupancy space.
The discharge direction of each nozzle plate may be
rotated via an Allen key inserted through the front
face of the diffuser into the centre of the nozzle plate
(figure 4).
Mode of Operation
The draught-free air pattern from the diffuser has
adjustable throw, spread and discharge direction (up,
down, left and r ight) via the rotatable hexagonal
nozzle plates (figure 2).
Four different hexagonal nozzle plate types are used,
each wi th a unique nozz le angle (angles flat ten
towards the diffuser left and right edges).
Each hexagonal nozzle plate may be rotated through
360 degrees to any one of six posit ions, thereby
providing six possible discharge directions for each
of the four nozzle plate types.
The SMARTEMP® Perforated Multistream Diffuser,
type PMW-AD (figure 1), is a side-wall diffuser that
provides high levels of draught-free thermal comfort
i n s uch spaces a s ho t e l r ooms, apa r tmen t s,
restaurants and commercial offices. The design is
both aesthetically pleasing and technically advanced.
Unlike standard side-blow air grilles, which produce
broad, low momentum air bundles that mix poorly
with room air, the PMW-AD discharges a multitude of
individual, high momentum air streams, each one of
which is highly induct ive. These produce largely
u n i f o r m t e m p e r a t u r e d i s t r i b u t i o n w i t h l o w
draught- r isk throughout the occupancy space.
Thermal comfort levels are high even when airflow
rates are high.
Figure 2
The Al len key shaft a l igns wi th the nozzle plate
stream axis to act as a visual indicator of the nozzle
plate discharge direction.
Due to its adjustable discharge direction, the diffuser
may be located symmetr ical ly or asymmetr ical ly
along the wall of the room. Throws of 3 to 9 m for a
d i ve rgen t a i r pa t te r n , and o f 6 to 18 m fo r a
convergent air pattern, are realised, depending on
the airflow rate and discharge direction. Thermal
comfort is high, due to the uniform temperature
distribution of typically ±1.5 K and low draught air
motion generally below 0.25 m/s in the occupancy
space.
Adjustable discharge elements are not included in
the return air variant of the diffuser.

Perforated Multistream Di�user 3
The PMW-AD consists of an aluminium mounting
frame surrounding a perforated metal front plate,
behind which are located adjustable nozzles, and
fixed nozzles. The nozzles are made of black plastic.
The fixed nozzles are located along the dif fuser
perimeter. The adjustable nozzles comprise angled
nozzles integrated into rotatable hexagonal nozzle
plates.
The mounting frame and perforated front face are
painted signal white (RAL9003) as standard, though
other colours are available on request. The PMW-AD
is available as standard in four heights (1, 2, 3 or
4-rows of adjustable nozzles) and in three nominal
widths. Bespoke widths are available on request.

PMW-AD : 112018
Perforated Multistream Di�user 11
The sound power level of the PMW-AD is low, even at high airflow rates. Owing to the lower pressure drop of the
diffuser, it is well suited for connection to fan-coil units; furthermore, it lowers the energy consumption of the
HVAC system.
Sound Power Level and Pressure Drop
The minimum mounting height (from floor to outlet lower edge) is 2 m. The minimum distance from the outlet
upper edge to the ceiling is 50 mm. The maximum difference in temperature between the supply and room air is
up to -12 K when cooling and up to +10 K when heating.
Layout Specifications
• Aesthetically appealing uniform perforated design.
• Low smudge risk – reduces cleaning costs.
• Uniform temperature distribution throughout the occupied space.
• Draught-free air supply.
• Quiet operation – suitable for hotel rooms.
• Improved heating performance.
• Suitable for 3 to 9 m throws (airflow rate and discharge direction dependent).
• Suitable for standard and low temperature supply air systems (ΔTsupply-room ≤ -12 K).
• Suitable for heating up to +10 K
• Suitable for constant flow and VAV systems turning down to 50%.
• Suitable for low pressure fan-coil applications operating at up to 20 Pa, as well as for higher pressure systems.
• Diffuser discharge direction adjustment via Allen key-avoids inadvertent adjustment (eg by cleaners).
