Modular Duct (MD) Panel

SEMCO® MD (Modular Duct) Panel Systems are an affordable way to connect double-wall, rectangular duct that requires higher pressures and longer spans to plenums or housings.

Key Differentiators​

  • Ease of installation provided by tongue-and-groove joint and factory-supplied cutouts
  • Independent testing for acoustical, thermal, and structural performance
  • Excellent cost-to-performance ratio

Product Overview  

Leveraging the FläktGroup® SEMCO MD Panel System using acoustical panels is much easier and more affordable than constructing double-wall rectangular duct in the field. It is the most efficient and cost-effective way of installing large double-wall rectangular duct extending beyond a plenum or housing.

SEMCO MD Panel Systems are designed with an integrated structure, eliminating much of the expensive structural steel and fabrication labor required when fabricating large, field-built double-wall duct. This design — combined with the “no screws” tongue-and-groove joint, factory engineered details, and complete assembly drawings — provides a complete and affordable pre-engineered “system.”

For engineered execution, time savings, cost reduction, and simplified project management, build smarter with SEMCO Panel Solutions.

Key Features and Benefits

  • Tongue-and-groove joint: Requires no screws in the joint, lessening installation time and leak potential
  • Fully insulated joint: Reduces labor compared to field-insulated joints while ensuring acoustical and thermal performance
  • Structurally sound: Allows for free span lengths up to 18 feet, reducing external and internal support steel required for large ducts
  • Factory-cut and framed openings: Decreases field labor
  • Design and construction ideal for high-pressure applications
