| High performance of blast resistance | Being able to stand multiple blast impacts with peak pressure reflected up more than 20 bar by long duration and maintain all functions after blasts. |
| High performance of protection | Being able to completely close in very short time to assure approximate 100% impulse block rate. |
| High ventilation volume | Ensuring the high air flow efficiency with the streamline design. |
| Automatic-reset | Being able to retrieve ventilation function automatically after the blast so as to minimize the maintenance. |
| Double acting | Providing protection from both positive pressure hit and sucking phase. |
| High corrosion resistant performance | Being made of chemical-resistant materials and fit for all corrosive conditions. |
