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.
