FC-BRV-21 high-performance blast dampers are developed for those applications where high air- flow-rate and perfect blast protection are required. It achieves unprecedented fast closing aiming the best protection by minimizing Rotational-Inertia blades thanks to Shaft-linkage-free design. It could stand blast overpressure reflected up to 5 bar and could maintain high-performance protection after multiple blast impacts.
FC-BRV-21 high-performance blast dampers could serve a wide range of applications, including OGP, energy, civil defense, and other applications where blast-resistant protection is required.
| Lightening speed in closing bringing perfect protection | Thanks to its innovative Shaft-linkage-free design, it can respond extremely fast to various blast waves and close the air passage with duration of only one half of average closing time of other alternatives in the market. |
| High-performance of blast resistance | The optimized blast resistant structure design enables it to withstand the blast peak pressure up to 5 bar reflected while assuring the perfect blast protection. |
| Automatic reset | It’s able to retrieve ventilation function automatically after the blast. |
| Double-acting function available | This product line offers double-acting option for special applications such as protection for nuclear power plants. |
| Customized large damper covering the whole wall for energy saving | Thanks to its modular design, a damper now could be as large as a whole wall to achieve high-air-volume at low-pressure-drop for energy saving. |
