  • Publication number: 20120276286
    Abstract: The present invention relates generally to a patch including a micro fiber glass and a polymeric binder, where the mixture forms an in situ porous patch that allows for active filtration after application to a leak or hole in an air filter. The mixture can be pressurized with a propellant within a housing prior to application to a leak or hole in an air filter. The mixture can also be applied manually to a leak or hole in an air filter, without the need to be pressurized with a propellant within a housing.

  • Publication number: 20100116031
    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.
