If the negative pressure is not greater than 60% of the rated opening pressure, installation of a domed vent has no extra benefit. For this application the KE style vent is an alternative to the domed GE. The KE provides long durability and aerodynamic advantages compared to the domed type, for example in cyclones. Pressure spike tolerance, integrated flange gaskets, cross rib and folded edges are standard KE design features.
**Below are common size events which are available however our state of the art manufacturing facility has the capability to produce this vent style in any custom size which your specific process may require. Please contact us directly to review your specific application needs.
