Torque Per Module (Nm) Calculation

NON-SPRING RETURN (ON/OFF)
e.g : a) 200 x 200 (mm) [Damper Size (Net)] = 0.2 x 0.2 = 0.04 M2
        x 10 (Factor) = 0.4 Nm

MFD-S (Motorized Fire Damper) Fail Safe Fast Running (SPRING RETURN)
e.g : a) 1,200 x 600 (mm) = 1.2 x 0.6 = 0.72 M2
         x 10 (Factor) = 7.2 Nm

         b) 1,500 x 1,200 (mm) = 1.5 x 1.2 = 1.8 M2
         x 10 (Factor) = 18 Nm

         c) 2,500 x 1,000 (mm) = 2.5 x 1.0 = 2.5 M2
         x 10 (Factor) = 25 Nm
