COMPOSITION AND METHOD OF OPERATION
conduit
Structure
The DRS air diffuser is composed of a front
plate (1) with blades that are integrated into
the exit of the diffuser (2).The diffuser is held
up by a concealed central screw (3).
raccord adapté
(spigot)
Operation
The blades divide the airflow into numerous
single high-induction airflows. The blades
integrated into the exit of the diffuser
ensure a horizontal air flow even at a slow
rate, while cooling up to a minimum of 25%
in variable air volume (VAV).
MAINTENANCE
LThe diffuser DRS of NAD Klima requires no
special maintenance other than periodic
cleaning.
We recommend cleaning the diffuser with a
multi-filament brush or duster microfiber that
you will pass softly on the diffuser. Thermolacquered finish for easy cleaning of the diffuser
as dust does not stick to it.

INSTALLATION IN A CEILING GYPSUM
DRS-Q
A) Opening in the gypsum
Choose one of the three (3) options
instalation shown at right.
Option 1 et 2
Calculate the dimensions of the diffuser
- Add 13 mm (1/2 ") in width and
13 mm (1/2 ") in length
- Cut the square in the gypsum
corresponding to these measures
(Diffuser size + 13 mm)
- Around this hole, insert a plaster frame
and fix it
NOTE : Make sure the final square hole is
13 mm (1/2 ") wider than the diffuser.
Option 3
Calculate the dimensions of the diffuser
- Remove 13 mm (1/2”)
- Cut the square in the gypsum
corresponding to these measures
(Diffuser size - 13 mm)
- Around this hole, insert a plaster frame
and fix it
NOTE : Make sure the final square hole is
13 mm (1/2 ") smaller than the diffuser.
B) Install the plenum
The plenum will be suspended through
four (4) suspension holes provided for
this purpose and use a metal wire.
As indicated in the drawing to the right,
install the plenum by adjusting its
height ;
according to option 1 and 2, the base of
the plenum must enter 1/8 " in the hole
or, option 3, the base plenum will press
the drywall outside the hole

INSTALLATION IN A CEILING GYPSUM
DRS-R
Option 1
A) Opening in the gypsum
Choose one of the two (2) options
instalation shown at right.
Option 1
- Measure the diameter ( ØD ) of the
diffuser
- ADD 1/2 inch or (13 mm)
- Cut a circle in the gypsum equivalent to
this new measure [ ØD+1/2 inch (13 mm)]
- Around this hole, place the gypsum
guide and fix it.
Note : Make sure that the final diameter of
the hole is well from 6.5 to 10 mm (1/4 "to
3/8") wider than the diameter of the
diffuser.
Option 2
- Measure the diameter (ØD) of the diffuser
- REMOVE 1/2 inch or (13 mm)
- Cut a circle in the gypsum equivalent to
this new measure [ØD-1/2 inch (13 mm)]
- Around this hole, place the gypsum
guide and fix it.
Note : Make sure that the final diameter of
the hole is well 13 mm to 19 mm (1/2 "to
3/4") smaller that the diameter of the
diffuser.
