Flamgard-Calidair Pressure Relief &
Backdraft Dampers
Flamgard-Calidair Pressure Relief and Backdraft damper
products are identical dampers, each cam be fitted
with an adjustable spring or counterweight system to suit
the individual application of each product. Pressure relief
dampers can be used for over pressure overpressure
situations or in the dynamic control of air pressure within a
space or room. Backdraft dampers are used to prevent
recirculation 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
can provide low leakage performance on return airflow.

CBD-01 Description:
The type CBD-01 Backdraught Damper has
been
designed to give maximum efficiency
under
arduous conditions and is suitable for
fitting with
the air flow in one direction only.
The dampers
may be installed vertically or
horizontally with
the air flow upwards.
CBD-02 Description:
The type CBD-02 Backdraught Damper has
been designed to give maximum shut-off
under
back-flow conditions and is suitable
for fitting
with the air flow in one direction
only.
The dampers may be installed
vertically or
horizontally with the air
flow upwards.
CBD-02C Description:
The type CBD-02C Circular Backdraught
Damper has been designed to give
maximum shut-off under back-flow
conditions and is suitable for fitting
with
the air flow in one direction only.
The
dampers may be installed vertically
or
horizontally with the air flow upwards.
CPR-01 Description:
The type CPR-01 Pressure Relief Damper
has
been designed to give maximum
efficiency
under arduous conditions and
is suitable for
the air outlets of electrical
equipment rooms,
control rooms and living
quarters. These areas
are maintained at
a higher pressure than
surrounding areas
to prevent the ingress of
hazardous gases.
The differential pressure is
usually 63 N/m²
although this may be increased
to provide
a greater safety margin. The dampers
may be installed vertically or horizontally
with
the airflow upward.
