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.
