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.
