The Hepa-Aire portable power vacuum is attached to the ductwork so that when it is in operation the dirt and debris dislodged by the aire-sweep is pulled into the Hepa-Aire.  The multi-stage filtration system uses Hepa filters as the final stage to assure that the exhausted air is "operating room" clean.

The Aire-Sweep portable air compressor is used to power the Aire-Sweep nozzle through the entire duct system.  As it is pulled back, compressed air is shot thruogh the nozzle loosening the debris and "sweeping" it back toward the Hepa-Aire portable power vac.
