How is the Air Duct Cleaning done?

Power Vac uses a system of high volume suction combined with high pressure compressed air cleaning. The vacuum system is hooked up to the main duct runs. This puts the system under negative pressure and provides the capture location for the material removed from the system. The cleaning is done by tools on the inside of the ductwork driven by high pressure compressed air. These tools agitate the inside of the ductwork and move the dust and debris back towards the vacuum capture system.
