FC-BRV-02-E rapid blast dampers are specifically developed for those applications where high air flow rate and blast protection are required. It could stand the overpressure up to 200KPa reflected with long duration and shut off in milliseconds. It could also stand multiple blast impacts and maintain full functions after blasts.
Compared with FC-BRV-02-S standard version, FC-BRV-02-E enhanced version carries a debris shield which adds extra safety margin regarding the high speed hits by flying debris.
Able to stand multiple blast impacts and maintain all functions after blasts.
Approximate 100% blast impulse block rate to assure the sufficient protection.
Completely closed within 8ms under 200KPa peak pressure reflected and this assures minimum passing through impulse.
High air flow based on normal open position. A 500*500 blast damper could provide exhaust air flow rate up to 3800 m3/h at pressure differential 100Pa.
Able to retrieve ventilation function automatically after blast.
Made of chemical-resistant material and fit all corrosive conditions.
Safely work in explosive atmospheres.
