The FDA2-12 round fire dampers are designed for use in
general ventilation systems to seal off smoke and fire between
adjacent fire partitions.
The fire dampers are classified according to EN 13501-3+A1:2010P
(Fire classification of construction products and building
elements). The fire resistance was tested as per PN-EN 1366-
2:2015 (Fire resistance tests for service installations — Part 2:
Fire dampers). The entire manufacturing process meets the
requirements of EN 15650:2010.
The FDA2-12 fire dampers can be installed in horizontal and
vertical fire partitions to provide fire resistance of EI 120
(ve ho i↔o) S (which may depend on the actual fire resistance
of the partition).
