Dynamic Air’s Multi-Port Switch automatically diverts granular materials from a single source, such as a pneumatic conveying system, to as many as fifteen different bins, hoppers or silos. The full-bore design permits unrestricted material flow to minimize material degradation and pressure drop for improved performance and to reduce the energy required for conveying. The unique design uses a Geneva drive system for reliability and exact trouble-free positioning. In addition, wearing parts can be replaced quickly with ease. There are no dead spots for material to collect, making the Multi-Port Switch ideal for applications where cross-contamination is a major concern.
