| Stand strong blast impulse | Able to stand multiple blast impacts and maintain all functions after blasts. |
| Unparralled rapid response speed | Completely closed within 8ms under 200KPa peak pressure reflected and this assures the safety by minimizing the passing through impulse. |
| High ventilation volume | High air flow based on normal open position. A 500*500 blast damper could provide exhaust flow rate up to 3800 m3/h at pressure differential 100Pa. |
| Manual-reset | Maintain at closing position through self-lock mechanism to provide extra safety. |
| High corrosion resistant performance | Made of chemical-resistant material and fit all corrosive conditions. |
| ATEX certified | Safely work in explosive atmospheres. |
