What is the function of the particulate deflector on a fabric expansion joint?

In certain conditions, a particulate deflector can be specified to reduce air-born particulate from falling down into the expansion joint cavity. This is most common on vertical ducting with the flow directions up and an upstream liner overlapping the downstream duct. The deflector presents an angled surface to the flow and eliminates a ledge for build-up.
