Abstract
Embodiments of the invention generally related to a method and apparatus for scanning a v-bank filter. In one embodiment, a method for testing a v-bank filter includes providing an aerosol challenge to an upstream side of a v-bank filter, scanning a downstream side of the v-bank filter with a probe having one or more rectangular sample ports, and providing samples taken through the probe during scanning to a test instrument. In yet another embodiment, a probe for scanning a v-bank filter is provided that includes a body having a plurality of rectangular sample ports. Each sample port is tapered to a port configured to connect to a sample tube. The long sides of the rectangular sample ports are arranged in a stacked parallel orientation.

9. A method for testing a v-bank filter, comprising:
-
providing a challenge to a v-bank filter having at least two adjacent banks of filter media arranged in a Vee configuration;
scanning a probe across an opening defined between the adjacent banks of filter media, wherein the probe is moved in a direction predominantly perpendicular to a short side of a sample port of the probe;
sampling air passing through the banks of filter media and into the probe; and
determining if a sample is indicative of a leak. - View Dependent Claims (6, 10, 11, 12, 13, 14)

15. A method for testing a v-bank filter, comprising:
-
providing a challenge to a v-bank filter having at least four adjacent banks of filter media arranged in a Vee configuration;
scanning an opening defined between at least one pair of adjacent banks of filter media with a probe having a plurality of rectangular sample ports, wherein the probe is moved in a direction predominantly perpendicular to a short side of one of sample ports of the probe;
sampling air passing through the banks of filter media and into the probe; and
determining if a sample taken through on of the sample ports is indicative of a leak through the filter. - View Dependent Claims (16)
