Abstract
Embodiments of the disclosure generally include a scan module configured to scan a filter for leaks. In one example, the scan module includes a housing having a plurality of scan probes disposed therein. A movement mechanism is coupled to the plurality of scan probes. The movement mechanism is operable to simultaneously displace the plurality of scan probes within the housing.

A scan module, comprising:
- a housing having a plurality of scan probes disposed therein;
- and
- a movement mechanism coupled to the plurality of scan probes, the movement mechanism operable to simultaneously displace the plurality of scan probes within the housing.
A filter housing assembly comprising:
- a filter housing having an inlet, an outlet, a filter mount, and a filter access port;
- and
- a scan module positioned between the filter mount and the outlet, the scan module comprising:
- a plurality of scan probes;
