Abstract
A filter system having in-situ scan capabilities is provided. In one embodiment of the invention, the system includes a downstream probe which may be rotated to scan the field of a filter installed in the system. The probe may be utilized for leak detection, velocity measurements, efficiency testing and the like. In one embodiment, one or more probes are rotated downstream of the filter to scan the downstream face of the filter.
Claims23
A filter system, comprising;
- a filter housing;
- a scan test housing coupled to the filter housing;
- a probe suitable for leak testing disposed in the scan test housing;
- and
- a mechanism for moving the probe in a rotational motion about a centerline of the filter housing while maintaining the probe in a radial orientation relative to the centerline.
2 more elements
A method of scanning a filter, comprising:
- flowing air through the filter;
- moving a probe in a rotational direction about a centerline of the filter while maintaining the probe in a radial orientation relative to the centerline to scan the filter;
- and
- testing the filter using samples obtained while moving the probe.
1 more element
A filter system, comprising;
- an upstream duct housing;
- a filter housing coupled to the upstream duct housing;
- a scan test housing coupled to the filter housing;
- a probe suitable for leak testing disposed in the scan test housing;
- and
- a mechanism for rotating the probe in a circle that scans an entire face of a filter disposed in the filter housing without opening the scan test housing, wherein the probe is maintained in a radial orientation relative to a centerline of the filter housing.
