Door-Fan-Test for gas extinguishing systems

If gas extinguishing systems are a building block in the protection concept, it is important to know how tight the space to be protected is. VdS has developed a so-called "door fan test" for this purpose. In this test, different pressure conditions are generated in the protected area and all outflows are measured. In this way, one knows exactly how large the leakage area is in each location.

The VdS experts precisely calculate the expected holding time of the extinguishing gas used in each case. The "door-fan test" reduces costly and time-consuming test flooding to a necessary minimum.
