NEW AT-FSD Series
Air Transfer Fire Smoke Dampers
For use above protective doorways and extended fire separations, often within ceiling voids, to allow the movement of air typically between the stairwell to the lobby and is intended as an unducted installation.
The optional purpose designed non-vision grille provides a discrete appearance.
Requiring access from one side of the fire separation wall only, the damper when installed maintains fire compartmentation in the event of a fire.
NEW LD and LDN Series
Lobby Dampers
designed for smoke evacuation and control within lobbies and are installed into extract shafts in multi-level buildings, to maintain tenable conditions in the common escape routes in the event of a fire.
LD series dampers are designed to work in fan power extract systems. Air is pulled through the damper and into
the extract shaft.
LDN series dampers work in natural draft (stack effect) ventilation which requires a minimum free area of one
metre square to comply with current standards and Approved Document B specification.
ETD Series
Elevated Temperature Volume Control Dampers Dampers
Designed for the control of air through the connecting ductwork and is suitable for continuous elevated temperatures up to 300°C.
In addition to operation at elevated temperatures, the ETD Series damper can also be used in conventional ducted systems where manual or motorised control dampers are called for.
A60 Series
Marine Fire Dampers
For use in marine applications to protect the integrity of fire rated bulkheads and decks.
Each A60 damper is controlled by an electrical failsafe spring return actuator combined with a thermoelectric tripping device (thermal fuse) and volt free contacts for remote status indication.
VC Series
Volume Control Dampers
For use in low to medium velocity H&V systems. Can also be used to perform actuated control functions where low closed blade leakage is not a requirement.
FSD-TD Series
Fire and Smoke Dampers
For use in heating, ventilation and air-conditioning (HVAC) systems at fire boundaries to maintain compartmentation and protect means of escape in case of fire. Also has the advantage of having reduced smoke leakage characteristics. They can respond to a smoke alarm input as well as having a failsafe thermal fuse.
