  • Process for removing dust deposits from ductwork
    Patent number: 6129095
    Abstract: The present invention discloses a process for cleaning ductwork. The method includes introducing air to a tunable sound generator for producing air pulses, introducing the air pulses into an air conduit at its proximal end where the air pulse cause the conduit to resonant dislodging and entraining contaminants in the air pulses, and collecting the entrained contaminants at a distal end of the conduit.

  • Cleaning system for removing dust deposits from ductwork
    Patent number: 5860187
    Abstract: The present invention discloses a portable cleaning system for ductwork and a method utilizing the cleaning system. The system includes a sound or air pulse generator for producing infrasound air pulses for short duration and introducing the air pulses into an air conduit which causes the air conduit to resonate or vibrate at a given infrasound frequency. The induced vibration causes contaminants in the ductwork to be entrained in the air pulses and carried with the air pulses to an exit of the air conduit where the air is filtered to remove the contaminants.
