| Shut Off Dampers
Flamgard's Shut Off / Isolation dampers are designed
to provide low leakage levels when subjected to high static pressures.
The rigid twin skin trafford aerofoil blade design has enhanced
stiffness which permits individual blade lengths of 1200mm to
be used without the need for center mullions. Ideally suited for
fan shut-off duty, these dampers are often installed with vertical
blade axis when positioned directly at the discharge of a centrifugal
fan scroll, to minimise turbulence and pressure losses. Tolerant
of arduous duct conditions, these dampers perform with minimal
maintenance within hot gas airflow systems

Heavy Duty Shut-Off Dampers
Flamgard-Calidair
types CCD-01 and CCD-02
Generally this type of damper is used to either balance or control the flow
of air through ducts. The final application of this type of damper will often
define the damper's description, these may include:
• Volume control
• balancing
• modulating
• shut-off
• smoke control
• bypass
• isolation.
The CCD -01 control damper is basically the same design as the CFD-01 fire damper
and shares many components. The only major difference is the Firelock blade
design of the CFD-01.

| Pressure Control
Dampers
Flamgard's Pressure Relief and Non Return damper
products are identical dampers, each fitted with an adjustable
counterweight system to suit the individual application of each
product. Pressure relief dampers can be used as a static relief
flap for overpressure situations or in the dynamic control of
air pressure within a space or room. Non return dampers are used
to prevent recirculation or back-flow of ventilation air. Particularly
useful as a low cost solution to prevent air recirculation through
an idle standby fan of a duty and standby ventilation fan configuration.
Both styles of this improved damper design provide low leakage
performance on return airflow.

| Blast Dampers
Flamgard's Blast dampers 'BLD01' (1Bar)
& 'BLD-02' (0.4Bar) are designed to prevent
blast forces entering ventilation duct systems. They are rigidly
constructed for this purpose and comprises of two sections. An
'eggcrate' section directs the blast onto the blade pack, which
consequently closes under blast pressure, isolating the blast
force and preventing blast damage or loss. The blade open position
is adjusted and held by a 'blast break' mechanism.

| Inlet Vane
Dampers
Flamgard's Inlet Vane dampers are rigidly designed
to meet the industry demands of zero downtime and low maintenance.The
use of I.V.D.'s at fan inlets saves energy in two ways:
1. At fan start-up a closed I.V.D. isolates fan
inlet, allowing the rotor to turn without air loading when at
speed the I.V.D. is opened.
2. During running the optimum angle setting of
the radial vanes causes the incoming air to 'swirl' in the running
direction of the turning fan rotor. |
