Procedure- Any Size Facility

   A technician connects the power vacuum to the facilitie's air handler with an 8" hose. Then he inserts the high-velocity air sweeper into the ductwork. He controls it with a hose connected to the truck's air compressor which supplies up to 200 pounds of air pressure.

   Another technician works inside the facility using a high-velocity blower at the registers. This works in conjunction with the vacuum and the appropriate air-driven tool, providing additional blasting power to remove particulate matter.

   Duct Doctor's patented vacuum truck is the industry's most powerful. With the vacuum and cleaning apparatus, all contaminants are removed from the ductwork and stored outside in the truck's debris collector for safe disposal.
