Abstract: A filter includes a first edge structure forming a first ring about an axis. A second edge structure forms a second ring about the axis, axially spaced apart from the first ring along the axis. A filter medium extends from the first edge structure to the second edge structure. The first and second edge structures are configured to engage an internal surface of a main bore of a valve housing. The filter medium is configured to allow air flow through the filter medium from the main bore radially outward through the filter medium to filter particulate out of an airflow from the main bore passing radially outward through the filter medium.
