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. 2
Installation frame (IF) PRI balancing plenum BDR plenum box Installation Concealed screw fastening (option) 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) The grilles are supplied with clips fastening as standard. Clips fastening is used with PRI, BDR and IF. 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. 3
K factor for installations with different safety distances (D= duct diameter) ØD PRI/S >8xD min 3xD 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. 125 200x100 10.1 12.6 160 300x100 17.0 21.7 160 400x100 17.0 21.7 200 500x100 27.7 33.9 200 300x150 27.8 33.9 250 400x150 47.2 55.5 250 500x150 46.2 50.1 250 600x150 45.8 51.1 315 800x150 80.8 83.3 250 400x200 51.2 55.5 315 500x200 92.9 83.3 315 600x200 82.7 93.1 315 800x200 79.3 83.3 BDR >6xD min 3xD 100 6 7 125 10 12 160 19 22 200 28 32 250 49 51 315 77 83 q v = k * p m Adjust the airflow rate by rotating the control spindle until the desired setting is achieved.

Pressure drop, throw pattern and sound data AWE or AWU, wall installation at a distance of 200 mm from the ceiling (with Coanda effect) 200x50, 200x100, 300x100, 400x100 500x100, 600x100, 800x100, 600x200 1000x100, 800x150, 1000x150, 800x200, 1000x200 1200x150, 1500x150, 1200x2000, 1500x200 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. 5
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 drop Pressure 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 Angle between vanes 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. Angle between vanes 6
