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. Vanes are available with 75 and 100 mm vane axis distances, to complete the entire range of standard duct dimensions Manually Operated Model AOBD-102-E Flat parallel-vane (SOBD-105) or opposite-vane (SOBD106) regulating dampers,...

Motor-driven LOAD LOSS TYPE AOBD-102-E Opposed aerodynamic vanes Opposed aerodynamic vanes Leaks % of maximum flow 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...

Weather louvres serie 200 Description Weather louvre for intake or discharge, model 210 TA In natural aluminium (without anodising). Special finishes available upon request. 210 TA Weather louvre for intake or discharge, 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. It can be provided with bird screen or insect screen. Fixing The louvres incorporate fasteners in the frame for installation. Upon request the frame can be delivered...

- As an accessory the weather louvres 210TA incorporate a birdscreen or an insect screen. Free area: (L-14)*(H-109) mm = [(1000-14)* (650-109)]/ 106= 0,53 m2 Face velocity (Vf) = 5000/0,53/3600= 2,6 m/s Pressure loss at intake for louvre with birdscreen: 30Pa. Pressure loss at discharge for louvre with birdscreen: 35Pa. - Can be built as a single module upto maximum dimensions of 3000 x 2000 mm (width x height). For widths above 1000 mm central reinforcements are incorporated as shown below. Example of selection For a known air flow rate which should pass through the louvre at, for example,...

Circular weather louvres TAC-200 Description Weather louvre, model TAC-200 Finishes Painted in white RAL 9010. Special finishes available upon request. Bird screen 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. Its circular shape makes it ideal for those installations where, for architectural reasons, conventional rectangular louvres are not acceptable. Fixing The louvre frame is provided with holes for...

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.

Graphs for pressure loss of TAC-200 TAC-200 Ø800 Example of selection For a known air flow rate passing through the louvre, the size should be selected such that the pressure loss corresponds to the requirements. For example, for an air flow rate of 3000 m3/h a selection can be made from: TAC-200 Ø630 with 85 Pa TAC-200 Ø710 with 55 Pa TAC-200 Ø800 with 14 Pa
