EI120S MFUSP 400 x 400
Rectangular fire dampers with a fire resistance of 120 minutes. When the temperature in the damper rises above 72 C the fusible link will break and the damper will close. When closed, the expanding material around the fireblade will swell and assure a fire and smoke-tight seal against hot air and smoke. The thin blade is made out of fire resistant calciumsilicate and ensures a relatively high net opening in the damper.

L (mm) = 400
H (mm) = 400

Y = (H-6)/2-230
