Pressure Surge Damper,
Type RK-F10
Preliminary notes
Pressure surge dampers shall protect rooms,
facilities and ductwork against pressure
blasts. Such pressure waves could be pro-
duced by chemical reactions, gas-explo-
sions or mechanical damages at pressure
vessels. They can reach in about 100 milli-
seconds a positive pressure of approx. 0.45
bar and their duration will take about 1 s.
(see graphic).

Application
In case of a requirement that single duct legs
or wall openings has to be open in normal
operation and to be closed in a pressure wave
resp. a pressure increasing situation, Krantz
recommend to use of their pressure surge
damper, type RK-F10.
According to the closing pressure an initial
tension will be adjusted at an installed spring
system. This initial tension ensures an open
position of the damper regarding wind blasts
and variation of pressure inside the duct sys-
tem. In open position and case of installation
outside of outer walls the damper also fulfils
the functions of a rain protection grille.

Pressure Surge Damper, Type RK-F10

Text for tender
Pressure Surge Damper,
Type RK-F10
For protection of rooms, equipments and air
ducts against shock waves.
The pressure wave can reach in about 100
milliseconds a positive pressure of approx.
0.45 bar and their duration will take about 1 s.
Pressure surge damper of sturdy design, di-
mensioned for shock waves up to 0.5 bar.
The function remains unreduced after a shock
wave.
Function
The requested closing pressure can be set
at a spring pull. The initial tension of the
spring pull is to be selected thus that the
blades are always open during normal op-
eration as well as in case of high wind pres-
sures or duct pressure fluctuations.
During normal operation the pressure surge
damper is open. In open condition the pres-
sure surge damper corresponds with regard
to appearance and functioning to a weather
and rain protection equipment.
In the event of a shock wave the pressure
surge damper closes suddenly. At pressure
drop the blades automatically jump back in-
to the position „open“.
The pressure surge damper requires no
accessory energy.
Design:
•Damper housing with connection frame
on both sides
•Built-in inclined blades with axis and bear-
ings
•Damper rods on both sides with spring
tensioning appliance
•Housing, blades and damper rods made
of special steel 1.4571
