Other colours available upon request
Composition
Deflection: fixed 0°
Single row of horizontal blades painted in white RAL9016
Frame made of mitre cut aluminium profiles painted black RAL9005
Individually adjustable vertical blades mounted at the back of the grille painted black RAL9005
Mounting
To be placed between two plasterboards in walls or ceilings and can be finished with stucco or plasterwork
Concealed fixing by means of specially designed frame to facilitate wall mounting and finishing with plasterboard paste or similar.
The horizontal fixed blades can be removed from the frame for easy mounting, cleaning and inspection.

Text for tender
Linear grille for supply or return air with concealed perimeter frame, type ALG-GYP, dimensions LxH (mm), with fixed horizontal blades (0º deflection), for installation in suspended ceiling or wall. Blade block that can be detached manually by means of pressure clips to access the interior of the unit or duct for cleaning, inspection or to access the filter etc.
Characterised by the absence of a visible profile, with only the horizontal blades of the grille visible, providing an overall pleasing aesthetic appearance. A control damper and individually moveable vertical blades can de fitted optionally to provide secondary deflection.

Vk = Average effective velocity through the grill in m/s
X0.25 = Horizontal throw in m at an endvelocity Vt of 0.25 m/s
Ps = Static pressure loss given in Pa
Lw(A) = Acoustic power in dB(A)
The throw X0.25 is given without deflection of the airstream at an end velocity of 0.25m/s. The distances are given for a smooth ceiling and installation distance of the center of the grille at 300mm from the ceiling surface. When mounted at a distance of 400 to 600 mm from the ceiling, a horizontal deflection towards the ceiling of 15° is advised. When mounted at a distance larger than 600mm from the ceiling, the throw distance X0.25 will be smaller than mentioned due to the missing coanda effect. In these cases and for all other special requirements, please contact our engineering office.
The values are given for isothermal supply air. Throw distances for cooling conditions at -11K can be calculated by dividing the X0.25 values with factor 1.1. For heating purposes at Dt of +11K a multiplier of 1.1 should be applied to the given X0.25 value.
Advised mounting distance between centers of multiple grilles in the same wall should be greater than 1/3 of the throw length X0.25 (without spread)
The pressure losses Ps are given for grilles without damper of with fully opened damper.
The acoustic powers Lw(A) are given for grilles without damper of with fully opened damper without room attenuation. Acoustic powers below 20dB(A) are mentioned as "<20" in the tables.
