Operation:
Complete with thermal fusible link set at 74ºC.
They are designed to be fail-safe, allowing the dampers to close automatically when the temperature in the duct reaches
the fuse design temperature..
Fire dampers with fusible link, FLD-S-U /
FLD-S-UD. Approval UL
Installation:
The dampers are designed for the lowest possible pressure drop. The technical department deals with each order
individually and supplies the client with a blade width for the desired height and ensures that the dampers have the
greatest free area when open and, therefore, the lowest pressure drop.
Blade width may therefore differ and can protrude outside the damper frame on one or more sides,
up to a maximum of 69 mm.
