F-B90
Description
Fire dampers represent passive fire protection and are designed to utilize compartmentalization to prevent the spread
of toxic gases, smoke and fire. The opening and closure of the damper blade can be activated remotely for actuator
versions. In case of fire when the air in the duct exceeds 72 °C or 74 °C, the thermal fuse melts in both actuator and
manual versions. The melting of the thermal fuse activates the closure of the damper blade automatically. The damper
blade is then mechanically locked in the closed position.
Highlights
• Short body without blade overhangs
• Can be used as Air-transfer grille with cold smoke tightness
• Duct connection from both sides always available
• Symmetric structure and mechanism accessible from both sides
• Fit installation, filling not visible
• Available with smoke detection
• One sided duct connection ended with Grille
Fire Resistivity
F-B90 fire dampers are CE certified following the Construction Products Regulation according to EN 15650:2010.
Dampers are tested according to EN 1366-2:2015 and classified according to EN 13501-3 + A1:2009. The fire damper
together with its installation form an inseparable part of the fire resistivity rating. F-B90 fire dampers are designed for
the installations listed and described in their Handbook.
