2 Series 100-200 100 Series Regulating Dampers Description Regulating damper with opposed and aerodynamic vanes, manufactured in aluminium (AOBD-102-E). The body of the damper has built-in air tight gaskets all around its inner perimeter to ensure a tight seal. The movement of the vanes is ensured by means of gears, achieving a proper friction, with manual or motor-driven operation.
Series 100-200 3 21 Models. Dimensions The dimensions indicated below are standard for regulating dampers. Regarding the length and height, they can be manufactured using intermediate dimensions, with 50mm vane axis distances.
4 Series 100-200 Load loss and air tightness graphs for aluminium regulating dampers Note: The air leak at damper AOBD-102-E is not greater than 2% in the closed position, with a static pressure of 1250 Pa. Example of Selection Knowing the air flow to be regulated by the damper, and using, for example, a front velocity of 6 m/s, the front surface of the damper can be obtained. This can be calculated using the following formula: Af(m2) = qv (m3/h) / Vf (m/s) β’ 3600 With an air flow rate (qv) of 10.
Series 100-200 Load loss graphs for steel sheet regulating dampers 5 Air tightness graphs for steel sheet regulating dampers Note: The air-tightness graphs for the steel sheet regulating dampers are based on a differential pressure of 250 Pa through the damper.
6 Series 100-200 Fresh air intake grilles 200 series Description Fresh air intake or extract grille, model 210-TA. Constructed in extruded aluminium. The design and shape of the blades make it completely sight-proof. As it is designed mainly for outdoor installation, it also prevents rainwater, snow, etc. from entering. Includes anti-bird meshes (12.5 mm standard mesh). On request with anti-insect mesh (1.6 mm mesh) or without protection and with or without filter.
Series 100-200 7 Fresh air intake grilles 200 series Installation Grilles are supplied with fixing plates in the frame to be built in to the wall. If specified on order, grilles can be supplied either with holes drilled in the frame to allow fixing via screws or with a mounting frame.
Series 100-200 8 Technical data 210-TA Table for forced ventilation based on a corrected face velocity of 2.5 m/s, which corresponds to a sound power level of 48 dB(A) when functioning as an extract grille and 52 dB(A) as an fresh air intake grille, considering an area of 1 m2 (use table 3, Sound Power Level Correction Table, to calculate other areas). Table 1.

Series 100-200 11 Technical data 210-TA Selection example Next, a selection example is shown in order to pre-select the specific dimensions of an air intake or extract grille. The starting point is the design flow rate, for example, 3000 m3/h. First of all, the frontal area required to give a face velocity of around 2.5 m/s is calculated, i.e. (3000m3/h)/(3600s/h) = 2.5 m/s*Afrontal(m2) ; Afrontal(m2)=0.

Series 100-200 13 Circular weather louvres TAC-200 Description Weather louvre, model TAC-200. Finishes Painted in white RAL 9010. Special finishes available upon request. TAC-200 Circular weather louvre, constructed in extruded aluminium. Its design and blade shape avoid vision through the louvre. It avoids penetration of rain water, snow, etc., since it has been principally designed for outdoor installation.
14 Series 100-200 General dimensions In the following general dimensions for the TAC-200 louvres are given in two tables : from Γ315 to Γ710 with insectscreen and from Γ800 to Γ1250 with birdscreen. Accessories In standard finish the TAC louvres incorporate an insectscreen from size 315 to 710 and a birdscreen from 800 to 1250.
Series 100-200 15 Graphs for pressure loss of TAC-200 In the following graphs the pressure loss is given for the TAC-200 louvres. For a given air flow rate (m3/h) the pressure loss (in Pa) can be obtained. In all graphs the effect of the insectscreen or birdscreen (according to louvre size) are already incorporated.

Series 100-200 17 Overpressure dampers serie 200, type 230 SP Description Overpressure damper model 230 SP. Finishes Natural aluminium (without anodising). Special finishes are available upon request. General dimensions See page 17. Other dimensions according to the drawings on the left. 230 SP Overpressure damper constructed in extruded aluminium. Incorporates a strip on the blades to obtain a higher shutter efficiency and noise reduction.
18 Series 100-200 Example of selection Standard dimensions For a known air flow rate which should pass through the damper (e.g. 3000 m3/h), and setting, for example, the face velocity at 4 m/s, the frontal area (Af) of the damper can be obtained by using the following equation: The following dimensions are normalised for overpressure dampers. With respect to the width, it is possible to provide intermediate dimensions. A(f) = Q(m3/h) / Vf (m/s) β’ 3600 = 3.
