Blast dampers are used to protect occupants and equipment of a structure against overpressures resultant of an explosion. The blast dampers normally protect air inlets and exhaust penetrations in an otherwise hardened structure. See the animation of Halton BDH blast damper in action.  

Halton BDH Blast Damper, 3D model

Halton BDH blast dampers protect against overpressure in offshore, onshore and heavy industry ventilation systems.  The BDH can be installed in rectangular ducts or wall openings.
When the blades are in the open position, the device does not cause significant pressure loss, noise or flow disturbance. The BDH has an adjustable arming mechanism. An open-closed indicator is visible on the outside of the damper.
