• Using our diesel powered, trailer mounted vacuum unit or portable equipment, we establish a high speed reverse air flow through the supply air duct system.
     
• This is accomplished by attaching a ten inch diameter suction hose from the vac trailer or portable negative air machines to the supply ductwork.
     
• This allows our powerful vac trailer’s airflow to lift and carry all the organic matter and debris we scrub from the interior of the supply ductwork out of the structure. This air flow also helps control any of the dirty material from being released into the home or workplace.

The next eight pictures illustrate this procedure.
