Supply air is supplied without vertical deflection and with horizontal deflection (rear vanes) through the vanes into the space, mixing with room air in front of the grille.
The flow pattern is adjusted by changing the angle of the adjustable rear vanes.
Wall installation for horizontal supply or ceiling installation for vertical supply.
The grille can also be used as an exhaust unit.


The grille is connected to the circular duct using either a Halton PRL balancing plenum or a Halton BDR plenum or alternatively directly to the rectangular duct using the IF/AWU installation frame.

Clips fastening (standard)

The grilles are delivered with clips fastening as standard.
The clips fastening is used with Halton PRL, Halton BDR and IF/AWU.

Concealed screw fastening

Concealed screw fastening is possible when the grille is installed with an installation frame (IF/AWU) or with a Halton BDR plenum; not with a Halton PRL balancing plenum. Holes for screws are provided in Halton BDR.

For ceiling installation concealed screw fastening is recommended.

Visible screw fastening is not possible due to the reduced width of the frame (18 mm).

The dimensions of the installation hole are LxH when installation frame is used, and (L-5)x(H-5) without installation frame.


In order to enable airflow adjustment and measurement of airflow rate it is recommended to connect the grille to the Halton BDR plenum or Halton PRL balancing plenum equipped with the MSM/MEM module.
The supply flow rate is determined by using the measurement and adjustment module MSM and the exhaust flow rate, by measuring the static pressure of the plenum.
Detach the grille and pass the tubes and control spindle through the grille.
Measure the differential pressure with a manometer. The flow rate is calculated using the formula below.

Adjust the airflow rate by rotating the control spindle until the desired setting is achieved.
Lock the damper position with a screw.
Replace the tubes and spindle into the plenum and replace the grille.

Airflow adjustment damper OD

The airflow rate is adjusted by turning the damper blades behind the grille with a screwdriver. The measurement is carried out when grille is installed.


Remove the grille by gently drawing it out by the frame. Use a screwdriver if necessary.
Clean the parts by wiping them with a damp cloth.
Push the grille back into place so that the clips lock (or fix by screwing on the concealed screws).

With balancing plenum Halton PRL or Halton BDR + MSM/MEM

Remove the measurement and adjustment module by gently pulling the shaft (NB. not the control spindle or measurement tubes!).
Wipe the parts with a damp cloth, instead of immersing in water.
Remount the measurement and adjustment module by pushing in the shaft until the module meets the stopper.
Push the grille back into place so that the clips lock.


The grille has horizontal fixed vanes and vertical adjustable rear vanes, and an 18 mm wide flat frame, anodised or epoxy-painted with a white (RAL 9003) colour.
Flow pattern can be adjustable by rear vanes.

Alternative 1

The grille can be connected to the ductwork using a plenum, with mineral wool as sound attenuation material.

Alternative 2

The grille can be connected to the ductwork using a balancing plenum, which comprises sound attenuation material of polyester fibre with a washable surface or mineral wool. The plenum has an airflow measurement and adjustment unit.

The grille is removable, in order to provide access to the measurement and adjustment module in the plenum.
