VariAire™ is a versatile machine for duct cleaners and other indoor air quality professionals who demand clean and not just clean looking results. The system reuses HEPA filtered indoor air to prevent inflow of contaminating outside air.  

The variable airflow capability enables VariAire™ to provide negative air flow for duct cleaning and containment fields or to act as an air scrubber to continuously filter the air during cleaning procedures.  Suction power is readily increased by connecting multiple VariAire™ units in parallel to increase air flow.
