The KER style vent is perfect for standard applications in powder handling and storage. The KER is suitable for plant equipment with static over/under pressure conditions up to 50% of the rated rupture pressure. A unique feature with the KER is that edge reinforcement in its design allows the KER to be mounted without an outlet flange thus reducing installation costs. Cross rib and folded edges are other standard KER 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.
