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.
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.
It’s able to retrieve ventilation function automatically after the blast.
This product line offers double-acting option for special applications such as protection for nuclear power plants.
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.
