DDR Dual-Duct VAV Terminal Units

Go beyond the typical dual-duct box

A dual-duct HVAC system increases precision, reduces cost, and can regulate temperature faster than a single-duct unit. A VAV terminal uses varying air volumes to heat and cool a space as needed. Together, you get the ultimate indoor air quality solution.

  • CFM: 100 to 4,100 CFM
  • AHRI 880 and ETL certified and labeled to meet industry performance and safety standards
  • Superior FlowStar air measuring probes provide for lower minimum cubic feet per minute (CFM) values, which reduces energy costs and noise while maintaining comfort in the zone
