Application
In general, WPA-D-N/Ex fans have been designed for application in the areas of explosion risk, where explosive atmosphere (i.e. mixture of flammable compounds in the form of gas and vapour with the air) is likely to occur. Increased fan pressure make them particularly efficient within installations of local exhausts, filtering units and also within a system of significant flow resistances. The fan can be applied in a system with an air discharge of required dynamic uplift.
