DIMENSIONS

With flow control damper OD total depth = 48 mm +

45 mm.

Special dimensions

In addition to standard sizes, other sizes can be

specially ordered. The maximum size is 1500x500 mm

(LxH).

It is possible to have a continuous grille of modular

design when the installation length is greater than

1500 mm. The maximum total length is 20 m.

Function

Supply air is supplied with vertical 15° angle 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.

In wall installations, the recommended distance from

the ceiling is 200 mm, when the supply air is directed

to the ceiling.(AWE)

The grille can also be used as an exhaust unit.(AWU)

Installation

The grille is connected to the circular duct using

either a PRI balancing plenum or a BDR plenum or

alternatively directly to the rectangular duct using the

IF installation frame.

Clips fastening (standard)

Installation frame (IF) PRI balancing plenum BDR plenum box

The grilles are supplied with clips fastening as

standard.

Clips fastening is used with PRI, BDR and IF.

Concealed screw fastening (option)

Concealed screw fastening is possible when the grille

is installed with an installation frame (IF) or a BDR

plenum, though not with a PRI balancing plenum.

Holes for screws are provided in the 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).

Size of the installation hole is LxH when installation

frame is used, and (L-5)x(H-5) without installation

frame.

Adjustment

In order to enable airflow adjustment and

measurement of airflow rate it is recommended that

you connect the diffuser to the BDR plenum or PRI

balancing plenum equipped with the MSM module.

The supply flow rate is determined by using the MSM

measurement and adjustment module.

Detach the grille and pass the tubes and control

spindle through the grille.

Measure the differential pressure using 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 in the plenum and

replace the grille.

K factor for installations with different safety distances

(D= duct diameter)

Airflow adjustment damper OD

The airflow rate is adjusted by turning the damper

blades behind the grille using a screwdriver. The

measurement is carried out when grille is installed.

Pressure drop, throw pattern and sound data

AWE or AWU, wall installation at a distance of 200

mm from the ceiling (with Coanda effect)

Note :

• When there is no coanda effect (installation greater than 200 mm from ceiling) the throw pattern must be multiplied by 0.7.• For exhaust use, adjust supply data by adding + 5 dB(A) and DPs= DPs x 1.2.

Sound power level with OD damper

Use of an OD opposite blade damper, will result in

increased pressure loss. The resulting increase in

sound level is computed from the selection chart value

and the formula below:

LpA = DLp + LpA

Kp= Adjusted pressure dropPressure drop in selection chart

Example :

ALE-1000x150 + OD/ALE

qv = 300 l/s

LpA = 31 dB(A) without damper OD/ALE

DPs= 50 Pa (desired pressure drop)

Kp = 50/11 = 4.5

LpA = 31 + 14 = 45 dB(A)

Throw length correction factor

When the throw length is adjusted with the rear

vanes, the actual throw length is obtained by

multiplying the value obtained from the selection chart

by the correction coefficient K1.

L0.2 (a) = K1 x L0.2

The correction coefficient K1 is the average for the

various grille sizes.

Pressure drop correction factor

When the throw length is adjusted with the rear

vanes, the actual pressure drop is obtained by

multiplying the value obtained from the selection chart

by the correction coefficient K2.

DPs (a) = K2 x DPs

The sound level increases when pressure drop is

increased. The correction coefficient K2 is the average

for the various grille sizes.

immersing in water.

Reassemble the measurement and adjustment

module by pushing the shaft until the module meets

the stopper.

Push the grille back into place so that the clips lock.

Suggested Specifications

The grille shall have horizontal fixed vanes with a 15°

angle deflection:AWE, no deflection: AWU and vertical

adjustable rear vanes, and an 18 mm wide flat frame,

anodised or epoxy-painted with a white (RAL 9010)

colour.

Flow pattern shall be adjustable by rear vanes.

Option 1

The grille shall be connected to the ductwork using

a plenum with mineral wool as sound insulation

material.

Option 2

The grille shall be connected to the ductwork using

a balancing plenum, which comprises polyester

fibre with a washable surface as sound attenuation

material.

The plenum shall comprise an airflow measurement

and adjustment unit.

The grille shall be removable in order to provide

access to the measurement and adjustment module

in the plenum.
