  • Patent number: 7174709
    Abstract: A turboscreen for use with diesel exhaust systems comprises a plurality of parallel metal V-shaped wires joined with a peripheral band. The turboscreen is reversibly provided within a housing assembly that permits removal of the interior screen without detaching the housing assembly from the exhaust system. The interior screen can be removed from the housing by removing and/or loosening bolts that connect the plates of the housing and withdrawing the screen. Maintenance times and repair costs are thereby reduced.
