Abstract: A system for in line in situ validation of an air filter of an exhaust filter system including a scan head, a means for facilitating movement of said scan head in the XY plane, a means for externally controlling the movement of the scan head from outside the plenum of the exhaust filter system in the XY plane, and a means for coupling the scan head to the means for externally controlling the movement of the scan head, is provided. The system can also include a scanning arm, inside and outside magnetic couples, and rolling means to facilitate movement of the inside and outside magnetic couples. A method for in line in situ validation of an air filter in an exhaust filter system is also described, which involves the use of the system for in line in situ validation of air filters of an exhaust filter system.

Abstract: An analyzing probe for insertion into numerous different environments to determine at least one characteristic of particulate matter suspended in a fluid stream of a test sample. Preferably, the analyzing probe includes a minimal amount of optical elements such as lenses that are subjected to the conditions of the environment of the fluid stream to be tested. Further, the analyzing probe is preferably designed so that it can be readily manufactured, operated and installed by relatively unskilled laborers.

Abstract: A modular pre-filtration apparatus may be beneficial to extend the life of a filter. The apparatus may include an impactor that can collect a first set of particles in the air, and a scroll filter that can collect a second set of particles in the air. A filter may follow the pre-filtration apparatus, thus causing the life of the filter to be increased.
